There is really only one viable solution to the Chum and Champ problem. That is to separate the two dogs.
Having read most of the articles about this issue, I am surprised that no one has apparently even thought about it.
These two dogs have obviously developed a “pack” mentality. So long as they are kept together they are going to continue to behave in this manner.
My daughter had the very same problem.
She had purchased two shepherd cross seven-month-old pups from a breeder. They terrorized the neighbourhood, barking constantly, chasing other animals, trying to get through the fence separating them from the next door family’s pets and generally being a problem.
When the City threatened to take them away, she solved the problem by giving the female dog to a friend who lived in another city. Both dogs became trainable and are now valued and loved pets.
As I see it, the solution is to let the one dog go to Mr. White and return the other one to the breeder in Saskatchewan, thus breaking up the “pack” permanently.
To those who will no doubt say that it would be cruel to separate these two who have always been together, I say it is a heck of a lot better than killing them!
