Hello, my dog has a few squidgy but hard lumps, they do not seem to bother him when we touch them but they are getting bigger. They appear like perfect circles.

These are mostly likely a benign tumor called a lipoma which is basically just fat accumulation. But since they are getting larger I would strongly recommend have your vet do an aspirate of them to ensure they aren't anything more serious. Occasionally some cancerous tumors will look like these lipomas which is why aspirating them at least once is important. I hope this helps!
