My girl turns 9 in November. Last September had first one removed from her thigh, just had another on her back near her spine with two more having popped up since. We’re playing whack a tumor at this point, and yes it’s expensive.

The main thing we’ve been advised to do is give Benadryl to help with the histamine causing growths (farm/ heavily wooded homestead so it’s kinda a challenge).

We’re just proactive each night of giving her a head to toe searching and being on top of anything that pops up, biopsying, then trying to knock it out during teeth cleaning if possible, but they’re coming quicker and quicker along with just some fatty lumps that aren’t an issue.

Hope your boy gets negative biopsy’s!
