How to get a solid recall

By now you have probably noticed there are a lot of pictures of my dogs running and playing without leashes. I want to make it clear that generally speaking my Greyhounds are leashed.  However, when we are in the country we allow our Greyhounds to be off leash.  Our dogs are familiar with our property and understand their “boundaries”.

My Greyhounds did not come with off-leash manners and it took a lot of work to train off-leash manners.  So how did I go about teaching my Greyhounds to come? Recall training is not a once and done type of command.  Recall training has to occur frequently and you have to be ready to give you Greyhound a huge payload when they come to you vs. following that amazing coyote scent or chasing an armadillo. 

At first we did a lot of work in the backyard.  I would send a Greyhound out and allow them to start their sniffing.  I would watch on the deck and when I noticed they were very interested in something I would call them and give them a high value treat—think canned dog food, mac&cheese, or raw tripe in a small container.  After they had successfully completed this on a small scale I increased the distraction and the distance. 

After mastering the backyard we would begin working on recalls at our local private dog park. This was a good location because it was safe but also full of new exciting smells and distractions.   Again I would wait until they became interested in something and then call them giving them a huge payload. 

We continued with this exercise until I felt they were ready to head to our country fields. 

The boys were relatively easy to teach a recall to.  Both Sashi and Jethro are huge momma’s boys.  They are not going far from me.  I can’t put on make-up without Sashi watching!  The cord was not cut with the boys.  Training a recall took a few huge payloads in a few different locations and they were hooked. 

Darla was not that simple.  Darla is a complicated Greyhound.  She is very independent and when I first got her she could take me or leave me.  However, she did want to hang close to Jethro and she loves food.  The issues with her recall came when she wanted to do more independent activities and realized that she could wonder off from Jethro.  This caused some stress—we thought all of our Greyhounds had great recalls but Darla did not.

Darla was deemed a flight risk and leashed.  Clint and I wanted Darla to enjoy the independence of sniffing and hunting around our fields.  We began reworking her recall and giving her another chance at off leash activities. 

We took her to the fields and the first time she did well and stayed with me, I thought that she had it!  The second time was not so pleasant.  As soon as we unleashed her she was off. Fortunately she was with Sashi and he has an excellent recall.  We called him and she remembered what she was supposed to be doing.  And came running back to us for her reward.  I want to note how important it was that we were happy and rewarded her when she came back.  She did not do exactly what we wanted her to do but we want her to associated coming to us with happiness and rewards, not us being frustrated.

After this experience we knew we had more work to do. We tried her off leash again this past week in our fields.  She did much better.  I have learned that once she is off leash she is going to run like crazy. The difference this time was that when we called her she did a turn-face and came back to us, ready for her jackpot reward. 

We will continue to do more and more off leash training with Darla and we will allow her more and more off leash time.  Hoping to balance her training with her positive experiences. 

No matter if you are considering allowing you Greyhound off leash or not, training your Greyhound to a recall is one of the most important things you can do.  We have to remember that accidents do happen and the better prepared you are the better chance you have a good outcome. Good solid recalls take time.  It is important to start slow and practice often.  Sometimes regression is part of the learning process and should not be considered a failure but an opportunity for learning.  Training you Greyhound should be a fun positive process for you and your Greyhound.

The Fovea has it

Science really gets me excited.  What is most exciting is when something new is discovered.  This could be a new treatment, new technology, or revisiting of a previously thought notion or idea.

Eyes are one of the coolest organs in the body.  They are windows to the brain and some would say to the soul.  In humans the vital sign of the eye is visual acuity—you know, when you have to cover one eye and read the eye chart.  20/20 vision means that you see the same as a normal eye would see at 20 feet.  20/100 vision means that you see what a normal eye would see at 100 feet.  As you might imagine it’s much more difficult to test the visual acuity of a dog’s eye—they can’t tell us what they see.  Due to this, some scientists believe that the visual acuity of the dog has been underestimated.

We know that dogs see differently than humans do.  For many years we have known that dogs can see much better in low light than us; they have rapid vision that allows them to detect rapid changes in the light, and, due to the placement of their eyes in their skulls, they have wider visual fields than we do (Miller & Murphy, 1995).

All of these qualities aid the dog, a predator, in its ability to hunt.  However, the acuity at which the dog can focus was thought to be diminished, as the dog is known to lack a fovea (Miller & Murphy, 1995).  Fovea centralis (fovea) is a structure in the human eye.  The fovea is a depression within the retina that contains a large number of densely packed cones type cells that are responsible for visual acuity (Beltran et al., 2014).

For years scientists have felt that the dog’s visual streak was responsible for their visual acuity.  The visual streak is an area in the retina with increased amounts of photosensitive retinal ganglionic cells and cone cells (Miller & Murphy, 1995).  However, in 2014 things changed.

In 2014 the canine retina was evaluated with in vivo (in life) and ex vivo (in death) imaging (Beltran et al., 2014).  The researchers found an area in the retina very similar to a non-human primate fovea, which they deemed the area centralis.  This area was tiny but full of densely packed cone cells (Beltran et al., 2014).  This area was not a fovea-like depression but was very similar from a histologic standpoint to what is seen in the center of the human fovea, the foveola (Beltran et al., 2014).

You may be asking why is she so excited about this? This information is incredibly important.  This indicates that a dog’s visual acuity is actually better than previously thought.  The visual acuity of a dog was thought to be about 20/50 (Miller & Murphy, 1995).  Based on the findings in this study, the visual acuity of the dog would be between 20/24 and 20/13 (Beltran et al., 2014).  That means that dogs could be able to see at 20 feet what a normal eye would see at 13 feet!

The canine eye is an important structure for multiple reasons.  For our Greyhounds the eye is important for racing, lure coursing, coursing, hunting, fetching, running through agility obstacles, and their everyday lives.  Just imagine having better than perfect vision and then adding a wider visual field, the ability to detect rapid changes in light, and the ability to see in low light—I would be overwhelmed with that much stimuli going through my brain all the time!  Dogs are complex animals and the more we learn about them the more I amazed by all they do!

Do Greyhounds think like us?

Have you ever wondered what makes a Greyhound happy?  Or even if your Greyhound experiences any emotion like we do?

I have.  Jethro recently had a spontaneous injury to his back.  He was paralyzed from the pelvis down.  We were lucky and he was able to have surgery to fix the issue.  He is getting better but he still has a long road ahead of him.

Jethro is a high-strung Greyhound that does not like to be still; he has “extra personality.”  He has been miserable while he has been sick.  He whines and seems listless.  He is only happy when he is eating, outside, cuddled up to Clint or me, or playing nose work.  We have ben playing a lot of games and that has made this experience better for the both of us.  Jethro may be the best trained of the bunch at this moment!

This experience made me think about the emotions dogs may feel.  I wondered how Jethro’s brain was processing his condition.  This experience made me want to know more about dog cognition.

Dog cognition is an up-and-coming field.  There are several centers around the U.S.  studying dogs.  We have learned that dogs are special compared to other animals.  Dogs are able to learn our cues even better than chimps and other non-human primates.

I was shocked that a dog could understand what I want him to do more quickly than a non-human primate.  A study published in Interactions Studies in 2009 looked at New Guinea Signing Dog (NGSD), along with four breeds of dogs registered with kennel clubs—the the Siberian Huskie, the German Shepherd Dog (GSD), the Toy Poodle, and the Basenji (Wobber, Hare, Koler-Matznick, Wrangham, & Tomasello, 2009).  The researchers tested three types of cues on these dogs—they set out two bowls of food, the first cue was pointing and turning toward one bowl, the second was handling a block and then setting it in front of a bowl, and the third was covering the dogs’ eyes and sitting the block in front of one bowl (Wobber et al., 2009).  In experiments with the NGSG and the kennel club dogs both reacted to these cues (Wobber et al., 2009).  This is incredibly interesting, as wolves do not do this (Hare, Brown, Williamson, & Tomasello, 2002; Virányi et al., 2008).  Furthermore, the NGSD is a breed that has had very little human involvement in their breeding and they still picked up on these cues similarly to the pure breed kennel dogs (Wobber et al., 2009).

This does not prove that dogs experience emotions as we do, but it does show that dogs are very in tune with humans.  They are paying attention to us and respond accordingly.  For instance, when I get my camera case out, my Greyhounds know we are about to go run.  Dogs pay attention to what we do.

There continues to be a lot of research focused on the dog’s cognitive system.  Hopefully someone will eventually be able to answer our question about the emotions our Greyhounds feel or don’t feel.

For now we have to do our best to not anthropomorphize our Greyhounds.  We understand that they are in tune with us but do not necessarily feel what we perceive that they feel.  We have to remember they are dogs and sometimes what makes them happiest is a nice run in a field, a good beef neck bone, an ear rub, or a nice game of nose- work!

Collars: To Martingale or not to Martingale

Besides poop-bags, the other most commonly used product for the greyhound is a collar.  When you adopt your greyhound most likely they will be equipped with a muzzle and a martingale collar. 

When I got my first greyhound I read a lot about the martingale collar.  Everyone seemed to recommend this as greyhounds have skinny necks and can “back out of their collars.”  What I was not clear on was that martingale collars should only be used for training or walking.

Unfortunately I found this out the hard way.  One day Jethro and Darla were playing.  They both had on martingale collars.  Something happened and Jethro got Darla’s collar wrapped around his mouth.  He was struggling to free himself and choking Darla in the process.  Both Greyhounds were squealing and I was freaking out.  I knew I had to act quickly.  The saving grace was that Darla’s collar was too big and by a miracle I was able to pull Jethro close enough to Darla to give the collar some slack and pull it over her head.  Darla and Jethro were OK; however, this could have ended in disaster if I had not been right there.  I vowed only to use a Martingale collars while training.

Greyhounds can be flight risks and per their adoption agreement they need collars on all the time.  I was frustrated with what I was going to do. 

I first ordered leather fishtail collars.  These collars are beautiful and I love to see Greyhounds sporting these collars, as they look so regal.  Overall they are very effective but there was one drawback.  My hounds are quite rambunctious and they have been known to take a notion to jump in the pool with a collar on.  Their leather collars were quite worn at about a year.  Sashi has been banned from leather.  He chewed through one collar and did some damage to another.  There had to be a better product.

One day I was watching a Greyhound race and noticed that the Greyhounds were being walked to the starting box with plastic buckle collars. I found Gun Dog Supply online and ordered a TufFlex collar for Sashi.  These collars also included a brass nameplate that is riveted to the collar.  They gave off a plastic smell when I first opened the package, but it dissipated overnight.

I love love love these TufFlex collars.  Now all three Greyhounds wear these collars.  They are easy to clean, pick up no odor from the dogs, and fit incredibly well.  My Greyhounds cannot back out of these collars as long as they are adjusted in the correct position.  I have been using these collars for about one year and can’t say anything negative about them. 

However, for most Greyhounds the safest walking collar is a martingale.  If you are concerned that you will forget to take it on and off, I highly recommend buying a martingale with a buckle.  I have used these collars in the past and they are effective but get dirty quickly–or maybe Sashi just gets dirty quickly!

 

I hope that one of these collar options suits you and your Greyhound!
