314 Hi Dave,
Welcome to then forums! How great that you are taking in Kayle, especially since you already had a bond with each other.
The starting point would be at the first layer of the Triangle working your way from the bottom up.
To answer your questions:
1. Kayle can definitely still respond to training, she is not too old. I would start from the beginning building a strong bond with her. There is a section on establishing a relationship in the aggression rehab section of this website Also begin training at Phase 1. Even if she knows some basic obedience it never hurts. You want to be certain that she knows all of Phase 1 before moving on to Phase 2 and same for Phase 3.
2. She is not too old to re-socialize with other dogs. I would start by teaching her to wear a muzzle comfortably. (see video in aggression rehab section)
3. Have you read through the Pack Structure layer of the Triangle? Are you following the rules closely? Following the rules in Pack structure can help increase motivation in dogs who are otherwise lacking. You didn’t mention if she is motivated by toys (ball/ tug etc) These can also be great motivators for dogs.
Remember to start in Phase 1 in the video section and the first layer of the Triangle and work your way up.
Keep posting your questions as you have them!Best,
Teresa
