My dog has a growing red bump with a black hole. What is it?

Updated on September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | 12 years and 9 months old | 14 lbs

My dog has a red bump on his back leg and a black hole in the middle. And it got bigger. Within a week. About the size of a dime now.

This bump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Tank to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.
