Practice Search for Buster in Federal Way

Trails laid in training exercises often lack some of the common features of scent trails of lost dogs.  This exercise covers two of those aspects: doubling back and circling.  We train our dogs to follow the strongest scent, which is not always the freshest scent.  If a dog takes a given path multiple times, he will leave more scent on that trail than he would simply moving from A to B.  When we are working cases, we often dip into yards and down dead ends, only to come back out and resume the direction of travel.  Dogs on the run would not know that a certain trail was a dead end before trying it, so this makes sense.  When dogs circle around a particular area, this seems to have been difficult for Kelsy to sort out in past cases.  She followed the strongest scent, which looped, and the trail out of the circle was just a single layer of scent, weaker than the scent in the loop.

Bonnie walked Buster on the trail shown at the top of the page.  She walked him on several double-backs, or feints.  By this I mean that Buster went down a path for about 40 feet and then came back and went the other way.  In the middle of this trail, Buster went around a loop several times.  Where the practice trail comes out onto the walking path under the power lines, the BPA trail, Bonnie and Buster could have gone one of two ways, either continuing on the BPA trail, or going out into the neighborhood and back.  I knew most of the trail in advance, which is useful because I can watch Kelsy's behavior seeing how she reacts to the presence or absence of scent.  The option of choosing one of two trails in the middle accomplishes two things.  First, it prevents me from steering Kelsy, either consciously or unconsciously.  By varying the tension on the leash, the handler can steer the dog instead of the dog steering the handler.  In training, you want to do this somewhat, rather than just allowing the dog to continue a mistake or search for coyotes.  Out on a case, you want to avoid steering your dog unless you are sure she has been distracted.  The second purpose of the optional trail is that it is a true test of the dog and handler, forcing them to work blind instead of knowing the trail in advance.

Kelsy did follow four of the five dead-end feints.  She skipped the one by the loop.  She also added a new dead end that she followed.  It turns out this was probably because she caught a direct air scent of Buster before continuing the trail to his hiding place.  Interestingly, Kelsy did not follow the loop.  She choose the single, freshest trail instead of looping on the strongest scent.  I predicted she would go around the loop once before finding the path out.  Kelsy had no problem choosing the correct trail on the A/B option where I did not know in advance the path chosen.  She went toward the neighborhood without hesitation, which was where Buster had gone. This video of a segment of the trail, where Kelsy first enters the BPA trail and checks out a feint, illustrates several things.  First, you see the tension that I put on the leash.  I don't just let her run when she gets a scent of something.  I keep a certain amount of tension as my way of asking, "Are you certain this is the right way?"  Second, you see her head come up, and she starts using her eyes instead of her nose when she has lost the scent.  Third, when she has the scent, she will get into a groove, with her head tipped slightly below horizontal, and the tips of her ears will flop in a signature mode.  When I see the tips of her ears waggle like that, I feel confident we are on the scent.  She also breaks into a gallop at the end, which is another strong sign she has the scent.  Fourth, she is distracted by a drunk on a park bench trying to get my attention, but you see that her body is still moving along the scent, and she quickly forgets about him. 

The single most important part of training is the reward.  You want to make the reward so extraordinary that your dog will remember that moment and make positive associations.  I have seen signs that Kelsy likes finding the dog, and that the find is the reward in many respects.  Still, we add other rewards to ensure that she loves her work.  She gets her treats, of course, but then we find a stick and play fetch.  Of course, we play fetch every day, but training day fetch is especially fun.  On this day, she found a rotten stick that crumbled when she chewed it, her favorite kind.  Kelsy did an excellent job on this extensive test, and she especially enjoyed her fetch at the end.

Search for G in Burien


G is very friendly with all people and animals.  He is 8 years old, in perfect health, 65 pounds, not neutered, with a collar but no tags, and with a microchip.  He wandered away from his home at 2nd Ave South and about 135th in the middle of the day.  He often wanders a few houses away, but this time he didn't come back.  I advised his owners that a search dog was probably not necessary because he was most likely with someone, based on his very friendly personality.  A couple of days later, the owner learned that G was seen playing with a black pit bull and its owner in the street on the afternoon that he disappeared.  Based on new information, I agreed to bring Kelsy out to work the scent trail, even though it was a little over two days old at that point.  Kelsy started at their house, and worked north along 2nd, dipping into yards and down a couple of dead end streets.  I still thought it was going to be a short trail, leading to a point where G was picked up.  I didn't even start recording the trail on GPS because I thought it was unlikely to go on very far.  After a mile, I started the GPS recording.  Kelsy followed a path into someone's yard, with permission, where G had checked out the smell of dozens of oyster shells in the yard.  She followed G's trail through an empty field at an abandoned church.

At a house with a couple of dogs chained in the yard, Kelsy thought the scent was very strong.  My guess is that G spent some time visiting with these dogs, so his scent collected there, stronger than the trail leading up or leading away.  I thought the trail might have ended there, but Kelsy picked it up again, leading south.  At a field where a school used to be, Kelsy got distracted by the scents of wild animals.  I asked the owner to present the scent article to Kelsy again so that she could get back on track.  Kelsy followed the scent down next to the freeway, down the off ramp, to 146th.  At the car dealer on 146th, a salesman said he had seen G running around the area for at least a couple of days.  We're not sure if this reported sighting was actually G, or a similar dog that had been turned in to animal control. We followed the scent to a dead end behind a grocery store.  At that point, Kelsy was tired, and the scent trail was still two days old, not a fresh scent.  If we had kept going, we could just continue to be two days behind forever.  I decided to stop the search for the night, and pick it up again if we had a sighting.

G's owners did get a sighting two days later, two miles east of where I stopped Kelsy.  They went there and found G.  It was surprising to me that he did not get picked up sooner because G was described as the friendliest of dogs, who  would happily jump into anyone's car. In hindsight, we probably would have found G if we had started searching sooner.  I gave the advice not to use the search dog at first based on the described personality of the dog.  The odds were greatly in favor of G being picked up the first day.  Probabilities are not certainties, though, and sometimes dogs defy the odds.

Practice search for Rita in Tukwilla



Kelsy and Komu swam in Lake Washington at Luther Burbank Park today after training.  Kelsy likes to find dogs, but she likes fetching balls in the lake better.  This was a great reward for her, hopefully enhancing her search performance.  She found Rita this morning on a short trail in Tukwilla.  Kelsy did not follow the exact trail, which is not unusual.  For the last fifty yards, she just ran straight toward the building where Rita was hidden.  She worked into the wind, which is best for her, but not something we can always count on. It's been so hot and dry for such a long time that I haven't been able to give Kelsy any proper trails to work.  I am looking forward to the rainy season, when it is easier to work Kelsy.

Practice Search for Buster again

At Bicentennial Park in Tukwila, we did a short wagon wheel trail after Komu's certification test.  The day was warming up quickly, so I didn't want to have a long trail.  I took a scent article from Buster, and then Buster, Sage, Rita, and Kody walked straight north.  In about 100 yards, they fanned out in several directions, west, north, northeast, and east.  Buster went east, leaving the common trail first.  When Kelsy followed a few minutes later, she overshot Buster's trail.  She looked back, giving her negative signal, but she also went up to the other dogs before going back to where Buster's trail branched off.  Once on Buster's trail again, she followed right up to his hiding place.  The temperature and humidity listed below were a couple hours earlier.  It was much warmer and drier when Kelsy worked.

Practice Search for Buster

This trail was about an hour old, three quarters of a mile long, with several turns and branches.  Kelsy pulled me along at a gallop most of the way.  When the scent trail entered the parking lot, Kelsy followed about thirty feet to the right of the actual scent trail.  The wind seemed to be from the north or northwest.  I notice that the wind is often from a different direction than the weather app says.

Practice search for Chachi in Puyallup.

This was a short, fresh trail. 
This was just positive reinforcement for Kelsy, letting her find Chachi on an easy trail.  The trail wound around several houses, about a quarter of a mile.  Kelsy had no trouble, and she seemed to appreciate an easy find.

Cleo in Discovery Park


Although we set out for Discovery Park at around 4 PM, communication difficulties with the foster of Cleo resulted in our not starting until almost 8 PM.  The trail led us on a loop through the woods, where it is unlikely any person would have gone on purpose, and then the trail dropped over a cliff.  This bluff falls about 250 feet over 500 lateral feet as the land falls toward the beach.  The top is sandy and unstable, and springs pop out of the hillside near the bottom.  I followed Kelsy down.  At the beach, the tide was high, completely covering the beach, leaving no place to search.  It seems Cleo must have gone down the bluff in search of water because the uplands are very dry.  Kelsy performed well, eagerly following a scent trail 24 hours old.  I did not receive any independent confirmation that she was on the right trail.  My sense, based on past experience, is that Kelsy was on the correct trail.
