Research Thuja oil. I've read many posts about dogs with lipomas that had good results. I am using it myself and believe it is having an effect for me. I am also taking thuja orally at a low dose. Not sure you should use that on a dog though? But definitely the thuja oil mixed with carrier oil, I use castor oil, rubbed on 2 to 3 times a day. I hope you have good results. Go on Amazon and search Thuja oil and read reviews you'll find some good info there.
