My dog has a lump near his Achilles. Will it go away or grow?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Male | 3 years and 10 months old

Trick had a lump removed and tested it's been diagnosed as a round cell tumor a benign histiocytoma he has another lump which they want to remove as well and test it's near his Achilles tendon and the vet doesn't want it to get bigger as it's harder to remove it's been there 7 weeks so is it likely to go the other one didn't go

Any lump has the potential to get bigger, and it may be a different kind of tumor from the lump he previously has removed. Given it's location, I agree with your vet that it's a good idea to have this lump removed from Trick before it gets bigger. I hope this helps!
