Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 1 year and 9 months old | 45 lbs
Hi, my dog has a bump on her ear for 6 months or so. We visited our vet when we found the bump. That time, our vet said if it gets bigger then we should come back. I saw some blood from the bump a few weeks ago(after she went to a beach and swam). The bump area's skin is hard. I don't think it's getting bigger. It doesn't look itchy. But I'm afraid that it might be a mast cell tumor. Are the chances high that it's just Lipoma or Histiocytoma?

By it's look only it's not possible to tell what type of tumor it is. this lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Sunny 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.
