My new puppy has an underbite. Should I be concerned about it?

Updated On September 23rd, 2025

We are about to adopt a puppy but we were not able to meet the puppy’s parents when we saw him. He is a springer spaniel/border collie/husky mix and we noticed he has a pronounced underbite. Should this be concerning or are there any questions we should ask?

While an underbite is certainly not normal, it is not likely to cause any major problems for your dog in the immediate future. Some very small percentages of dogs with an underbite or overbite will develop some difficulty eating or with dental problems. However, this typically happens sooner than later. The great majority of them live perfectly normal lives and just look a little more unusual that the average dog. You are likely not going to get any useful information from the adopters regarding this, since the presence of an underbite is not necessarily genetic or hereditary. Hope this makes sense.
