A lump containing several small bumps on a dog's skin

Sorry, English is my second language, so I may not be precise in terminology and sentence construction. Today I noticed my dog ​​has a lump near his elbow. The lump rises above the skin and 3 more smaller lumps are formed in it and are white in color. The lump does not bother the dog when palpated. Physiological parameters are normal. Appetite and mood are normal. The dog is on a natural diet. We are currently traveling and will be able to see a veterinarian upon arrival home. Perhaps someone has encountered something similar? I would appreciate your feedback, thank you.  

Hi - there is a lot that I don't know about this lump from looking.  Furthermore, you don't say where home is, or how long it is before you expect to arrive. It may be that your vet would like to aspirate or biopsy the lump to rule cancer in or out, so it may be preferable to have a consultation sooner rather than later.

@connections puzzle You should see a veterinarian to have your dog's tumor removed.

@burrito crafMaybe the little dog has a skin-related disease? How do you clean it every day?
