The vet said it’s unusual to see it so young, and then also said he had never seen a case so bad, even in adults. His gums looked like hamburger meat and it broke my heart. He had given no indication that it was painful to eat the dry food. We’ve had to get steroid shots every month since we started and the vet said THAT can lead to diabetes, so we need to get the teeth out and hope that’s the last of it. Surgery is on the 7th, so hopefully that’ll be the end of it. I hope your girl fares much better!
