My friends have recently bought a Border Collie from a breeder here in Nebraska. He seems to have an aggression issue with his own tail whenever he eats or has a bone. It isnt allergies, he actually growls at it and bares teeth while he is eating and bites his own tail. He has no fur left on the last half of his tail and has actually bitten the tip, 1/2 inch to an inch off his tail!! They have taken him to the vet and the vet is completly at a loss as to why he is doing it.
He isnt just chewing on his tail while he is bored or anything, it is only when he eats or has a bone and he is actually "fighting" his own tail as if he thinks it is going to take his food. He has no aggression twards anyone or anything else, not even when he is eating, it is only his tail. They have been applying medicine to the tail and keeping it wrapped to try to let it heal. They do not let him eat without supervision, and have stopped giving him bones. They have talked to the breeder who has never heard of this issue before, and the vet is unsure of what to do besides one of those shade things around the neck while he eats to prevent him from biting himself. He is currently 4.5 months old. Has anyone ever heard of such a thing or have any advice for them. Thank you so much in advance!! Jayne Duncan
