About 6 months ago I rescued an 18 month old male Lab from a family that didn't want him. The dog came from an Amish breeder in Indiana known for supplying puppies to Chicago area pet shops. This family bought him from a pet shop when he was 12 weeks old. As he began to get big the family had two small children and apparently he became too much for them so they chained him in the backyard.
When I got him 6 months ago he was wild, had never been neutered, socialized with other dogs, people or on a leash. He is afraid of everything and everyone. Our walks are torture for him. He immediately urinates all over if anyone approaches him or tries to pet him. He also continues to mark in the house. I have crate trained him and put him through a very structured and thorough housebreaking routine. I started from the beginning as if he were a puppy. I also immediately had him neutered and checked by my vet and he is in perfect health. He has been through obedience training and he knows and responds to all his commands yet he keeps doing the submissive urination and lifitng his leg in the house as if he's out in the park. There's no warning that he'll lift his leg at all, just walks by something and let's go.
I've had trainers and a behaviorist evaluate him and one said that he had a genetic anxiety disorder.
My vet has now put him on anti-anxiety meds. He's almost 2 now and when inside, he can never be out of my sight unless he's in his crate. When outside he is terrified if anyone cames near him.
He is a great dog but seems unable to relate to his environment.
Can these behaviors be changed ?
Any thoughts??
