My puppy has a growing watery lump under its chin. Should I see a vet?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 7 days old

My one week old puppy has a huge watery lump under his chin. I'm getting worried because it gets bigger and bigger each day. My other dog had this type of lump already but it's gone now without any medications. Should I be worried or just let my puppy on its own just like my other dog?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Tootsie! I would worry it is an abscess. The skin looks red and bruised and the "water" you feel may be puss. Since Tootsie is so young that makes him more fragile than older puppies, meaning he may deteriorate quickly. I suggest you take him to the Vet for an exam and if they think it is an abscess then antibiotics can be provided. I hope this helps and I wish you all the best!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This may represent an abscess for example. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. If this is the case, your veterinarian may choose to treat him locally with cleaning and drainage as he is a bit too young for antibiotics. Good luck!
