Why does my dog have a pink bump with a hole in the middle?
Hello, my name is Dr. Shines and I am happy to help.
Dogs can get all kinds of skin masses as well as things like pimples and ingrown hairs. Most of these lesions will be benign but a few will be cancerous. Unfortunately, you can't always tell from looks alone.
If the bump doesn't seem to hurt or bother Bentley, you might try applying a warm (not hot) compress every couple hours for 10 minutes. If this is an ingrown hair or pimple, this might help it to come to a head.
If it seems to bother him, have him examined.
If the bump is still there in 2 weeks, I'd go ahead and have Bentley examined. There's one type of skin cancer called a Mast Cell Tumor and they commonly look red/pink, hairless and raised. If the doctor is concerned, they'll test it.
I hope this helps and please feel free to reach out with any additional questions.
