Hamsters get lumps under there bums that are the same as the skin color even if there not male. The bumps are commonly found below the tail.
I have some in my thighs, under the skin. My doctor told me not to worry about them, they don't hurt, just annoying. I have done some research and they are probably lipomas, just fatty lumps. I'm not a doctor but it's my two cents.
Possibly canine cushings disease.
These are systs , your vet should check these out in case they are malignant or benign
That dog really, really needs to see a vet ASAP.
Hmm I think these are lymph nodes
Ask your doctor about Erythema Nodosum. Erythema nodosum is a type of skin inflammation that is located in a certain portion of the fatty layer of skin. Erythema nodosum (also called EN) results in reddish, painful, tender lumps most commonly located in the front of the legs below the knees. The tender lumps, or nodules, of erythema nodosum range in size from 1 to 5 centimeters. The nodular swelling is caused by a special pattern of inflammation in the fatty layer of skin. Erythema nodosum can be self-limited and resolve on its own in three to six weeks. Upon resolution, it may leave only a temporary bruised appearance or leave a chronic indentation in the skin where the fatty layer has been injured.
