a friend has a jack russel
it pees in house not outside
it will hold it all day out side and as soon as it gets inside it pees.one vet says it is seperation anxiety???How do you treat that if you agree?
Wel this sounds like a training problem. basiclly, your friend has not trained the dog properly. In the dogs mind, he is doing right. You have to reverse this thinking. Your friend can find 100's of books on dog training at a local library or bookstore. good luck, vetcare
