My dog has a growing white bump on his tongue. Should I be worried?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 1 year and 6 months old | 27 lbs

My dog has a small white sore/ bump on his tongue. It is maybe a millimeter in diameter, and has grown (slightly) in the past month. I thought maybe he hurt it playing but since it has grown I ruled that out. He is a year and a half (give or take) and I've had him just over a year. He already had canine papilloma, what could it be? He is behaving completely like his normal self- eating, drinking, playing with toys, going outside, energy levels are all normal. Should I be worried?

Any lumps which grow in size are a concern and should be assessed by a vet. Sedation may be required to fully check the size and depth and possibly sample a mass on the tongue so keep him fasting before the appointment
