Are the spots on my 3-week-old puppy's mouth puppy acne or strangles?

Updated on September 23rd, 2025

Pet's info: Dog | Perro de Presa Canario | Male | unneutered | 20 days old | 2 lbs

Hi, I have noticed that some of my 3 week old puppies have spots on their mouths. Some only have the one spot whilst some have quite a few and others have non whatsoever. One of the pups at first the spots were quite inflamed and red but now have gone down and look white. Can they get puppy acne at this age? I know strangles can be a worry but their lymph nodes are not swollen and they do not have spots anywhere else and are all fine in themselves feeding and playing etc. thank you

Hello, thank you for using PetCoach.

These bump are pustules, so yes, sort of like acne but it is really inflammation of the hair follicles. It can be the beginning of puppy strangles so still continue to look out for that. You have two options:

1. Do nothing and just monitor them and let their immune systems take care of it as long as they are otherwise fine.

OR

2. You can use these medicated pads once daily on the affected areas until the issue is resolved.

Sometimes these get very infected and inflamed, in which case, you will need to take them to the vet as oral antibiotics will be needed.

Hope this helps. Best wishes.
