Hello, I just noticed a line on his tooth and it looks like it might be cracked? He is still eating and playing just fine. This is something that I should get checked out or just keep an eye on it?
I would recommend having your dog checked out by your veterinarian. Depending on if the tooth is fractured or cracked and how it is fractured or cracked it may require them to remove the tooth. Right now it may not be causing your dog an issue right now but it can cause a problem at any time. This can not only create pain when eating but also a tooth rooth abscess.
