These sound like fatty cyst deposits, if they move and don't appear to be attached thats a very good thing! (not cancer), therefore you can not treat like a cancer. If they are not overly large as to inhibit the mobility of the dog, leave them. Taking them off, just because, is risky. If you want to treat the dog homeopathically, this would only be one very small symptom to work from, without any others, there is nothing to do about it. One of my females has them as well, they are non painful and really not large, she is also otherwise healthy.
