Wounds: Healing from the Inside Out

I love wounds. My love for wound care began when I was a brand new nurse working in the ICU. Wounds are challenging to care for. Despite many innovations, wounds can be difficult to heal. I like a challenge it seemed natural for me to find wound healing fascinating. I am always amazed by the bodyā€™s capacity to heal itself. But more than the challenge of wound healing, I enjoy the always-advancing treatment options in wound medicine. Wound treatment continues to look for more effective and efficient methods for wound healing.

In human medicine, we have sophisticated options for wound treatment. Ā These technologies are being utilized in vet medicine as well. Dogs do seem to have an upper hand on us humans–they are better a healing. Their bodies seem well prepared to deal with wounds and more resistant to infection. However, dogs can get some nasty wounds that need intervention.

Today I want to talk about topical agents that are most commonly used in wound treatment. Ā By now we have all heard of honey and sugardene dressings and antibiotic dressings but how do the work? How do these treatments advance wound healing and are there any other options to help wounds heal?

First, let’s talk about wounds. There are many different types of wounds but the pathophysiology is similar in all. The first stage of wound healing is the inflammatory stage. This is when inflammatory markers are attracted to the wound through vasodilation. These cells are working to stop the bleeding and rid the body of any infections. In the second stage of wound healing, collagen fibers are forming. These fibers need oxygen and vitamins to create granulation (new) tissue. A wound must have granulation before epithelialization or the connection of epithelial cells occurs. In the final phase of wound healing, the body continues to lay down college fibers, creating a scar.

One key part of wound healing is oxygenation of tissue. Generally speaking oxygenation of our tissue comes from our blood via the arterial system. The same thing occurs in wounds. The goal of wound management is to dress the wound with a material that will aid in oxygenation. That seems easy enough but there is one problem, necrotic tissue. The necrotic or dead tissue is kryptonite for wound healing–sometimes this has to be manually removed or debrided. The goal of wound care is to select a dressing to cover the wound that will prevent tissue death, keep the wound bed moist, and support healing.

Now letā€™s talk about antimicrobial dressings. Antimicrobial dressings generally contain iodine. Ā Iodine prevents infection. Sugardene is a mixture of sugar and iodine and an example of this. While these agents prevent and treat infection, they do little to aid in re-epithelialization. Antimicrobial dressings would be great for an abscess or dirty wound. This dressing aids in healing by preventing infection.

Another popular dressing that has gained a lot of attention is Manuka honey. Manuka honey is a raw honey made by bees that pollinate the Manuka bush in New Zealand. This dressing is thought to both be antimicrobial and anti-inflammatory. There are some that reports that suggest wounds do heal faster with Manuka Honey than antibiotic mediums. Ā The use of honey as a wound dressing has been practiced for many years and considered an effective treatment. Honey is also cost effective.

The last dressing that I want to mention is Zinc. Zinc is not an antimicrobial it is a trace element found in the human body. Zinc is an antioxidant that helps with oxygenation of the wound bed. This increased oxygenation in the wound bed is thought to help with re-epithelialization, aiding in wound healing.

I have used all of these topicals for wounds at one time or another. I am a fan of zinc for pressure ulcers in Greyhounds. As you can see in these photos above, Zinc increased granulation tissue, allowing the wound bed to close. Ā Zinc was a game changer for us.

All of these dressings have their purpose. It is hard to compare them head to head as their properties are different, what might work for a large leg ulcer may not help a minor abrasion or infected wound.

Wounds are challenging. The points to remember when dealing with wounds is to keep the wound bed oxygenated by preventing/removing necrotic tissueā€”selecting the appropriate wound dressing is essential. When in doubt or if a wound is not healing see a soft tissue vet. I have been blown away by the knowledge of our soft tissue vet as well as their continued patience for wound healing.

In addition to using the best wound dressing for the wound at hand, ensure that your Greyhound is using an appropriate bed. If pressure ulcers are a concern make sure bony prominences cannot be felt on the underside of the bed, I am a huge fan of these beds to prevent pressure sores. Finally, ensure that your Greyhound is receiving the best nutrition possible as wounds heal from the inside out!

Here is a video of Jethroā€™s bandage change. I hope you all find it helpful. And yes, Jethro is a very good boy!

Amateur Running Sports: Open Field Coursing

Today’s post is from guest writer Audrey Hsia. Ā Audrey is a Greyhound enthusiast. Ā She owns Greyhounds, Hungarian Greyhounds or Magyar Agars, and Dachshunds. Ā Audrey’s knowledge on Greyhounds and running sports is extensive. Ā She has been a wonderful resource to me as I have expanded my knowledge on the caring and keeping of Greyhounds. Ā I hope you all enjoy this post as much as I did.

Open Field Coursing, or OFC as it is called by most participants, is a competitive field sport for sighthounds in which the dogs are set on live, wild jackrabbits and judged on their ability to pursue the hares. Although competitive coursing in the United States dates back to about the 1860’s, modern open field coursing originated in the 1960’s with the founding of the National Open Field Coursing Association (NOFCA). NOFCA was and remains the primary sanctioning body for open field coursing in the United States, but there are several other smaller groups organizing coursing events as well. These include the North American Coursing Association (NACA) and The Coursing Conservancy (TCC).

No matter which group is putting on the coursing meeting, the format is largely the same. OFC meetings can be either one of two types: breed stakes or mixed stakes. Breed stakes, as the name implies, are stakes where only breed is competing against itself. Mixed stakes are open to all sighthound breeds that are recognized by the sanctioning body, and dogs entered are competing against each other regardless of breed. Stakes are advertised as either breed stakes or mixed stakes prior to the running of the meeting; that way participants can choose to run their dogs only in breed stakes, only in mixed stakes, or both types as they please. In order to make a valid stake of either type, there must be at least five dogs entered to fill all of the placements.

Before the coursing meeting begins, all participants will meet at a designated location, usually a restaurant or gas station located near the field where the dogs will be running. At that point, roll call will be conducted and if the stake is large enough (15+ dogs), dogs will be divided into separate fields with separate judges. Once roll call is complete the courses are drawn into trios or braces at random. Each dog in a course is assigned a colored blanket (yellow, pink or blue), which the judge will use to identify the dogs during each course.

After all that prep work is done, everyone gets in their cars and drives out to the field. With few exceptions, the courses will be run in the order they were drawn. The course that is up is called to the front, while all the other participants line up behind to form a gallery, which will help to flush out the hares as the line moves forward.

Once a hare is raised, the huntmaster will assess whether or not all the dogs are sighted on it and/or whether or not it is likely to result in a viable course. Assuming all dogs are sighted and everything else is promising the huntmaster will yell “Tally ho!” signaling to the handlers that they may release their dogs. The judge, who is either walking alongside the gallery, or perched on top of a hill or tall vehicle will then observe the course and score the dogs on their performance. The dogs are scored using a category scoring format with each category being worth a certain amount of points. Categories include things like speed, agility, and endurance, with extra points being awarded to dogs who touch, take or attempt the take the hare. Unlike traditional English or Irish coursing, American open field coursing places a fair amount of value on dogs making kills during their courses. In fact, most if not all American OFC titles require that the dog make at least one kill during its career in order to make champion.

Preparation for open field coursing is very labor intensive for the dogs and handlers. Due to the unpredictable nature of the sport, it is imperative that the dogs be as physically fit as possible. Courses can go on for several minutes, and theĀ haresĀ frequently lead the dogs into terrain that can be difficult to navigate safely. As such, the best thing a handler can do to prepare a dog for open field coursing is to bring it up from a young age in preparation for the sport. This means giving their puppies ample opportunity to explore and exercise on varied terrain so that they can learn how to use their bodies safely and efficiently while they are still young and haven’t reached their peak speed. As adults, daily conditioning is essential especially if your dog is not competing on a regular basis to help maintain their fitness. Brisk walks, road work, and opportunities to gallop are all very good ways to keep a dog conditioned for open field coursing.

Besides preparing your dog physically for an OFC meeting, there are many other things you need to prepare for a day in the field. Comfortable walking shoes are a must, as OFC meetings can go from sun-up to sundown if hares are not plentiful. Depending on the terrain, you may also want to invest in chaps or gaiters to protect your legs from thorns and weeds which you may encounter while trying to flush the hares from their hiding places. Dressing in layers is also advisable, as temperatures can fluctuate throughout the day. Investing in a comfortable backpack or hunting vest is also a must, as you will need to carry plenty of water for you and your dog, as well as snacks, a first aid kit, coursing blankets, extra leashes, slip leads, and a GPS or other tracking device if you choose to use one.

Overall, Open Field Coursing is a challenging sport, but for those who make the effort it is guaranteed to be rewarding in a way that no other sighthound sport can be.

Why performance matters: What Racing Gives Us

Last week I discussed why performance is historically important to the Greyhound.Ā Ā WithoutĀ performanceĀ we would not have the Greyhound we know and love.Ā Ā I also discussed that coursing was where all Greyhound sport originatedĀ and explored some of theĀ historyĀ of the breed.Ā Ā This weekā€™s blog is about the recent history of the Greyhound in the U.S.

In the late 1800ā€™s the Irish created park coursing, which used similar rules of coursing that were used in Britain; however, the size of the course was smaller.Ā Ā Many feel that this is when folks decided that even with shorter courses the greyhound was still exhilarating to watch.Ā Ā The Irish developed their coursing club in 1916.

The first mechanical lure was used in 1876.Ā Ā It was used in a 400-yard straight course.Ā Ā This was not found to be exciting and many spectators did not enjoy this type of sport.Ā Ā It took about 30 years for the mechanical lure to become popular.

In theĀ meantimeĀ Greyhounds were coming into the United States.Ā Ā For the mostĀ partĀ these dogs were settled out west to help with jackrabbit population control.Ā Ā Even General Custer was a fan of the Greyhound, using them as scouts prior to battle.Ā Ā You bet these Greyhounds wereĀ coursedĀ out west!

In 1906 the National Greyhound Association (NGA) was organized.Ā Ā The NGA was responsible for registering Greyhounds in America and keeping up with Greyhound breedings.

In 1919 the first Greyhound track was opened in Emeryville, CA.Ā Ā This was designed by the entrepreneur OwenĀ P.Ā Smith and financed by George Sawyer.Ā Ā The track used a mechanical lure that was propelled by a motorized cart on the inside of a rail.Ā Ā The total length of the track was about 3/16thĀ of a mile.Ā Ā These early races were poorly attended but Sawyer had an idea on how to fix this.

Sawyer encouraged Smith to introduce wageringĀ and they began allowing wagering on races.Ā Ā While attendance increased, they were still unable to make money and the track ended up going bankrupt.Ā Ā Smith took his mechanical lure and went to Florida.

Tracks were popping up throughout Florida in the 1930ā€™s.Ā Ā These tracks were helpful for tax income throughout the Great Depression.Ā Ā More and more states allowed Greyhound racing to flourish.Ā Ā At Greyhound racingā€™sĀ heightĀ it was the sixth most popular sport in America.Ā Ā Ā However, often times when money changes hands undesirable attention comes.

There were speculations of illegal actives associated with greyhound racing. Ā These speculations did not come to anything and did not hurt American Greyhound racing; it was at its height in the late 1980ā€™s and early 1990ā€™s.

In 1987 The American Greyhound Council (AGC) was created.Ā Ā The AGC oversees Greyhound welfare from puppyhood to retirement.Ā Ā The AGC inspects Greyhound farms to make sure they are within their guidelines for proper Greyhound care.Ā Ā Once the Greyhound arrives at the track there are state regulation in place for Greyhound welfare as well as track contracts that kennels must comply with to continue racing.Ā Ā The AGC follows the numbers of greyhound adoptions.Ā Ā They also follow the economic impact of greyhound racing.

The early 2000ā€™s were a hard time for the racing.Ā Ā There were reports of mistreatment of Greyhounds throughout the news. Ā There was also a decline in live betting. Ā This caused multiple tracks to close their doors.

During these hard times, the people of Greyhound racing did not tuck their tails and run.Ā Ā They worked tirelessly with the AGC, adoption groups, and state regulatory bodies to ensure the welfare of the Greyhound and the integrity of racing.Ā Ā CurrentlyĀ 90% of all retired racing greyhound are adopted or returned to farms as pets or for breeding purposes, a much higher percentage than that of other dog adoption organizations in the U.S. Ā Ā The goal of AGC is to expand adoption efforts and increase that to 100%.Ā Ā This percentage is sure to increase as more and more people want Greyhounds as pets and more adoption organizations are willing to take on complex cases.

In addition to creating wonderful pets, Greyhound racing is important economically.Ā Ā It is estimated that the racing industry employs 14,000 people with an annual payroll of 194 million dollars.Ā Ā The racing industry also pays an estimated 86 million in taxes to federal, state, and local governments.Ā Ā The racing industry donates an estimated 6 million dollars to charities, including greyhound adoption groups.

Greyhound sports have always been the essential component of the Greyhound.Ā Ā Without coursing and racing, the dog that we love would most likely not be in existence.Ā Ā Continued support of athletic activities of the Greyhound is needed to promote this breed.Ā Ā Continued recognition of performance is essential to for us to be the best stewards of our breed.Ā  Thanks to the great work of AGC, adoption groups, and the NGA we are able to welcome these professional athletes into our homes to be wonderful companions. Ā We all know that greyhounds give us fulfillment but we must remember that our Greyhounds need fulfillment as well.Ā Ā Greyhounds can find fulfillment in multiple ways but the most specialĀ isĀ in their passion for the chase!

Why Performance Matters: A Simple History of Greyhound Coursing

Feature image from The Greyhound & the Hare

 

For many years it was thought that the Greyhound originated in Egypt and the Middle East.Ā Ā However, there were written accounts in the 1800ā€™s stating that the Greyhounds originated from Celtic lands.Ā Ā In 2004 this was proven.Ā Ā The paper titled ā€œThe Genetic Structure of the Purebred dogā€ evaluated the molecular structure and differences in 85 breeds of dog.Ā Ā This study proved that the Greyhound, along with the Borzoi, Irish wolfhound, and other herding breeds, were of European descent and in fact were genetically different from the African and Middle Eastern sighthounds.

There are accounts of the Greyhound noted throughout British history.Ā  In Shakespeare’s playĀ King Henry V, Shakespeare uses the Greyhound in the King’sĀ monologues priorĀ to battle. Ā Henry V said to his men, ā€œI see you stand like greyhounds in the slips,Ā straining upon the start.Ā The game’s afoot.ā€Ā Ā Shakespeare compared Henry V’s armies to Greyhounds because he knew the keenness, tenacity, and passion of the Greyhound.

The Tudor family was also fond of the Greyhound.Ā Ā Henry the VIIā€™s coat of arms included bothĀ a red dragonĀ as well as a white Greyhound.Ā Ā Henry the VIII had a great love of coursing, then called hunting.Ā Ā It is noted that he converted some of his landĀ into a course and it was used by two coursing societies.Ā Ā However, that land has now been repurposed into a golf course.

From The Greyhound & the Hare

In the sixteenth century QueenĀ ElizabethĀ I and Lord Norfolk developed the first coursing rules, ā€œThe laws of the leash.ā€ These rules formalized the rules for coursing, focusing on the scoring of the Greyhoundā€™s performance, rules for the slipper, and the handling of theĀ hare.

Coursing focuses on the Greyhoundā€™s greatest skill, the speediness of the chase.Ā Ā More points are awarded to the Greyhound for speed and ability to pass another Greyhound than actuallyĀ taking-out theĀ hare.

Throughout the Tudor reign, the Forest Laws were in effect; these laws were established in the middle ages and strictly enforced by William the Conqueror. Ā People and dogs caught breaking these laws were mutilated and often times killed.

Coursing continued to be a sport of the nobles, waxing and waning in popularity throughout the reigns of Charles I and II.Ā Ā During the reign of George the III, in the eighteenth century, coursing no longer was a private sport for the nobles but a sport for gentlemen.Ā Ā Most of the participants coursed either Greyhounds or Whippets and made wagers on their hounds.

In 1776 The Lord of Orford in Swaffham, England created the first coursing club.Ā Ā The original ā€œlaws of the leashā€ created by Lord Norfolk were still in effect and used.Ā Ā Interest in coursing grew and more and more clubs originated.

From The Greyhound & the Hare

 

By the time of the industrial revolution, more people had free time and money to participate in hobby sports.Ā Ā Coursing was also much cheaper than foxhunting.Ā Ā Greyhounds and Greyhound coursing took off. Participants of the sport realized that if they had a winningĀ hound there was additional income for breeding and selling puppies.Ā Ā While these breedings were documented within the kennels, there was not an official Greyhound stud-book until 1882.

So why is this a big deal?Ā Ā Coursing gave us the modern day Greyhound. The competition of coursing created a well-engineered dog that was thrilling to watch and fast.Ā Ā The history of our beloved Greyhound gives us more insight into why people continued to breed Greyhounds and created the Greyhound that lives with us today.

There is still more to the story.Ā Ā With the invention of the mechanicalĀ lure Greyhound Racing was created.Ā  I will talk about racing in part two of this series, stay tuned!
