Hi! My 11.5 yrs old blk lab have a lot of lipomas all over his body, 90% There's 2 big ones the size of a grapefruit on his chest and one near his groin area. His vet isn't concern about them but I am. Is it normal for him to have so many lipomas? Why is he getting so many of them? He has new ones next to the old ones. What causes lipoma? Thank you!

Lipomas are just accumulation of fat and are very common in older dogs. As they age they develop more if they are prone to them. Dogs that are overweight are more prone to them but I see them very commonly on dogs that are an ideal body weight. I usually do not worry about them unless that are causing issues with mobility or they are bothering the dog. If they are causing issues, I would talk to your vet about having them debulked. When they are this large, it is impossible to completely remove them and they will likey regrow, but debulking them will allow him to be more comfortable. If they do regrow, they will likely never get as big as they are right now, but of course I cannot guarantee that. I hope this helps!
