Lump with open sores.

Species: Dog
Breed: Rottweiler
Age: 8-11 years
Hello. My dog has a very large lump on his leg with open sores which bleeds occasionally. The lump is very warm and developed over a months time. I suspect that it might be a hot spot but was wondering if I could send you a picture to help confirm. Thank you for your time.

lump on dog's leg

I can't give you an official diagnosis over the internet, but what I see on this photo has me very concerned. This looks like it could be some sort of a cancerous tumor. Unfortunately rottweilers are quite prone to getting cancers.

I have seen some benign tumors that looked like this and then started to ulcerate once they grew too big. But I think that we need to prepare ourselves that this could be something serious.

Another thing that I have seen that could look like this is something called a lick granuloma. This is something that starts off as a wound and then as the dog licks it more and more it can become an ugly mass. But I can't say that I have seen one get quite this big though.

It really would be a good idea to have your vet take a look. They will likely do a fine needle aspirate of the lump which should tell us exactly what the problem is. It's possible that surgery could be done to remove the lump.

I hope everything is ok.

Dr. Marie.
