We would be happy to answer any specific questions you have about fatty tumors on dogs :) In general, I can tell you that they are quite common in older dogs, and most often occur on the sides, chest, and abdomen. They should feel soft and squishy, and are usually freely moveable under the skin - not attached to the underlying tissue. They are benign, and typically do not cause any clinical problems.

If Freddie has some lumps that you think may be fatty tumors, it would be best to have them checked by your vet to make sure. If they are fatty tumors, they would not be expected to cause any problems in most cases.

    Hi and thanks for your post on Petco Pet Education Center, formerly Petcoach!

    If the masses have been diagnosed as fatty tumors by your veterinarian, then there is no need to worry too much. These fatty tumors do grow but typically do not cause a lot of problems. Sometimes they can grow quite large and impede mobility but unless that starts to occur, there is no need to worry.

    I hope this helps and I wish you and Odie the best!
