Another updated bio on Tyson. This guy has worked through a lot of challenges in his life. He was rescued from a shelter way back in March of 2009 and spend his first 6 months in a foster home that had some minor issues with him but loved him to death. He did have some separation anxiety and onlead reactivity at the time; the reactivity wasn't too serious but he was barking a lot when alone and peeing in his crate. Over the next three months he made progress and we were happy when he was adopted on trial in November of the same year to someone who wanted a dog that needed work. Things started off well and he attended a Desensitization and Counterconditioning workshop that winter. He did very well in class and wasn't even too bad as far as reactivity. However, his adoptors only attended some of the workshops and reported an increase in his reactivity once the sessions were concluded. Long story short, he spent 8 months in this home before they told us they no longer wanted him, and back he came.

He went to a foster home that was in a low density suburban area, and fostering with other dogs. We were disappointed that he'd been put on Prozac by his owner against our recommendation, and we immediately weaned him off. His separation anxiety was definitely improved, and we watched him on lead to see the severe onleash reactivity that the adoptor had reported. Initially, we didn't see it. Dogs who have sat with us for a while tend to not get any interest, and he sat for a year and a half in this foster home before he finally got a great adoption application. As always, we disclosed his past behavioural problems. His new adoptive parents quickly came to love him, but we soon saw a return of the onleash reactivity. His behaviour is not 'typical' onleash reactivity in that he's in a worked up state most of the time that he barks at strangers. Sometimes there isn't even tension in the leash.If instead of giving the food reward when the trigger appeared as is the premise of counterconditioning a dog out of reactive behaviour, they instead waited until he became reactive and THEN tried to distract him with the food reward - they would've inadvertently been rewarding the behaviour, and making it more deep seeded. Based on the reactivity we saw when he went to an adoptor in a more densely populated suburb, and on all of his behavioural reports since he's been with us, we believe that that is what took place, and his adoptors inadvertently were missing the correct timing for food rewards to countercondition what was mild to moderate leash reactivity, to where he was now highly leash reactive with people and other dogs.

For safety reasons, and with broken hearts on both ends, his adoptors and Barlee's agreed that he was not the right dog to live in a condo in a high-traffic suburb. He's back in foster care, but we are now tackling the challenge of reversing what's now a deep-seeded onleash reactivity towards people and dogs. Due to the high level of reactivity, and because as a result walks are stressful for Tyson, we have chosen to discontinue walks until we can get him to a better place and make some headway on this. He's fostering with another graduate of our DSCC course and will be getting one on one support to the best of our ability.

About Barlee's Angels Rescue Network

About Our Rescue Group...

Please see our website at for full information.

Barlee's Angels Rescue Network (BARN) is a non-profit, all-breed animal rescue based in Guelph, Ontario, Canada. We are a group of volunteers dedicated to helping animals in need. We do this by taking in homeless animals, fostering them in the homes of our foster volunteers, tending to their veterinary needs, and adopting them into carefully screened homes. We work on any behavioral problems while they are in foster care as well as basic house manners, crate- and housetraining.

Barlee's Angels are usually abandoned, unwanted, abused or stray animals. These animals come primarily from shelters. Barlee's strongly supports responsible pet ownership and therefore will try to help people to keep their pets rather than accept the pet as a first option. As with all rescues, space is limited and if we can help some pet owners through the problems that are causing them to feel they must give up their pet, we can use that space for other animals in trouble.

Only if we are able to, BARN will accept an owner surrender into the rescue and rehoming program, but the pet must be vaccinated, altered, accompanied by all of it's possessions (eg bed, toys, blanket) and a surrender fee may be required to offset some of the substantial costs of caring for and rehoming an animal.

BARN provides foster care for our companion animals, evaluates temperament and personality, provides veterinary attention as necessary, spays or neuters and then matches the animal with a home that is suitable for that individual animal. This can often take months and it can be very costly. An adoption fee is charged for the pet and followups are ongoing to monitor the success of the placement. Wildlife are rehabilitated and released when possible.

Our Adoption Process...

Please see our website at for full information.

The adoption process for Barlee's Angels and for most rescues is a thorough process that involves an adoption application, reference checks, and discussion about the potential adoptive home, including a home visit. We appreciate your patience and understanding during this time - and we'd like to stress that this is a necessary part of our job. We feel that when we rescue an animal we have a responsibility to ensure that we place it in a home that is equipped and committed to caring for the pet for the rest of its' natural life.

Please understand that filling out an adoption application or complying with any of our approval procedures in no way guarantees the acceptance of an adoption application. We reserve the right to refuse an applicant for any reason, at our discretion. We also reserve the right to investigate for the purpose of verification information given in adoption applications, and not to disclose any such information revealed in such investigations.
