We cannot answer your question here....Get your puppy to his Vet and let the Vet do what's necessary...Bacterial infections setting in would be my first thought of complications.....Your Vet will be able to tell you if it's a defect or not.....Good luck & let us know.....Karla
There is absolutely NO WAY to answer this question online, the dog must be examined by a veterinariay to determine not only the extent of his injuries but also whether or not he may even need surgery to repair the damage. The fact that he can urinate without a problem NOW means nothing, if the injury doesn't heal correctly it can lead to problems later on in life because of a build-up of scar tissue. This seemingly minor problem could end up being a huge problem later on if you don't see to it ASAP.
