Losing her beloved English bull terrier Jester in a beaver trap in February hit Becky Barber of Afton hard. Months later, she still canāt go back to the spot where it happened.
But she decided to channel her sadness and anger over Jesterās death toward something positive ā training other dogs to avoid traps in the Wyoming outdoors.
āI decided that, you know, I could be angry, I could be hateful. But before his heart stopped beating, I made a promise to Jester that his death would not be in vain,ā Barber told Cowboy State Daily.
In what could very well be a first in his profession, trainer Mike Parmley ran about a half-dozen dogs from the Afton area through a course this week ā with the aim of conditioning them to avoid traps.
Parmley runs Rattlesnake Alert dog training, based in Utah.
For seven years, heās taught dogs to have a negative association with the sight, sound and scent of rattlesnakes, and thus avoid them.
And so, inspired by what happened to Jester, why not apply the same methods to teach dogs to steer clear of traps?
Judging by the preliminary results, it looks promising, said Barber. She took her surviving dog, a year-and-a-half old English bull terrier named Kaia, through the course on Sunday.
āShe did very well. Itās amazing seeing the results with the dogs, Iām fairly confident this will make a difference,ā she said.
āJesterās Legacyā
Barber calls the training program part of āJesterās legacy.ā
It all started one terrible day in February.
Barber took Jester, 8, and Kaia for a romp up a road in the Swift Creek drainage near Afton.
The road is plowed during the winter to allow municipal crews access to water supply infrastructure. But itās closed to public vehicle traffic, so Barber and other townspeople figured it was safe place to take their pets for off-leash walks.
However, Jester got caught in a beaver trap that was placed just off the road, and despite Barberās efforts to free him, he died in front of her.
The Wyoming Game and Fish Department issued a citation in connection with an incident in Swift Creek Drainage east of Afton, spokeswoman Breanna Ball told Cowboy State Daily at the time. The agency didnāt release the name of the person who was cited, but the incident seems to match up with what happened to Jester.
Barber said sheās continued to take Kaia for walks in different places. She hasnāt mustered the courage to return to the Swift Creek Drainage road.
āItās still too fresh and too raw for me,ā she said. āI believe that the trap (avoidance) training was very successful and that it works. Itās my own trauma that keeps me at bay.ā
Rattlesnakes Make Good Dog Trainers
Whether teaching dogs to avoid snakes, traps or other hazards, the approach is simple, Parmley said.
For the rattlesnake avoidance training, he uses live snakes, which he keeps in enclosures on his property though a special permit with the Utah Division of Wildlife Resources.
Rattlesnake avoidance training takes place during the warmer months, because the snakes canāt handle cold weather.
At the beginning of each training season, he de-fangs the snakes, so that they canāt bite the dogs and inject them with venom during the training.
The snakesā fangs grow back, he said.
āTheyāre kind of like sharks are with their teeth, the snakes have backup fangs that come in,ā he said.
He begins by āintroducing the dogsā to the snakes, so the dogs get a clear idea of the snakesā appearance, the sound of their rattles and their scent.
Then he puts the snakes on the ground, and whenever the dogs get to close āIāll nip themā with an electronic collar.
āPeople call them āshock collars.ā I donāt love the term shock collars. I donāt shock the hell out of the dogs, I just give them a little nip,āā Parmley said.
Merely repeating that exercise with the snake in the same place wonāt work, he added.
āWhat many people donāt realize about dogs is that theyāre āplace specific,āā he said. āThat means, whether good or bad, if something happens to them in a certain place, they associate it with that place.ā
By moving the snakes around to different locations, the dogs learn to associate the snakes, not the locations, with a bad experience.
The final test is to put the snakes into a mesh bags, with their rattles constricted. That way, the dogs canāt see or hear the snakes ā they have to go on scent alone.

Same Negative Association Concept
That approach has been used by trainers to avoid not only venomous snakes, but porcupines and other hazards, Parmley said.
But as far as he knows, nobody else has used that method to get dogs to avoid traps.
Getting dogs to associate the sight of traps with bad experiences was one thing. But since smell is the strongest sense for most dogs, scent association is vital.
Parmley solved that quandary by reaching out to trappers in the Afton area. He quizzed them about the scents they use to bait their traps.
Then, he applied those scents to his training course. It seems to have worked, he said.
Even so, heād like to come back in the spring and run the dogs through more scent-based tests, to see if the lesson sticks over the long term.
Because trappersā baits vary by region, training would have to be tweaked by region to include the right scents.
Parmley isnāt sure where it will lead, but heās hopeful that he can run trap avoidance courses for dogs during the colder months, when itās too chilly for his rattlesnakes.
āWell see, I donāt know what kind of interest this will get,ā he said.
