Speaking of shock collars and dogs doing inexplicable things...my buddy's neighbours have a pair of dogs, both female, that have lived together for years without incident. Just recently though they went at each other in all out battle and severely injured each other. They had to use shovels to separate them. It was mentioned they have an invisible fence with shock collars on both dogs and have them turned up to maximum output and I was wondering if they thought the shocks they were receiving were somehow because of the other dog and decided it was time to settle it in the way dogs do?
I've can't recall hearing about two dogs getting into a potentially to the death fight when they've lived together incident free for years. Any ideas?
