My 10 yr. old chocolate lab just developed a large plum-sized lump on his outer left hind leg. It isn’t hindering his walking or his getting up or down. It’s not a lipoma. What can it be?

Without an aspirate or biopsy we cannot say exactly what the growth is. I do recommend if it is large and not a lipoma consistency to have it removed by your veterinarian. They then at that point can send it out to a pathologist to review and see what it is exactly. Thank you for using Petco Pet Education Center, formerly Petcoach.
