how very sad for you and for poor mum, i hope she is coping with the others, and they are all fine.
many tears rescue had a poodle x pup with a very small anus a little while ago, nicknamed billy no bum....he had to be kept on a special diet, thats all i remember im afraid. I assume this happens in crossbreeds alot, especially if the 2 breeds are different sizes, they take on different features??
