My puppy is sneezing, tired, and cranky. Could it be allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Male | neutered | 4 months and 14 days old | 33 lbs

My puppy has been sneezing very often for the past 3 days. Doesn't matter if we're inside or outside. His appetite hasn't changed, but is a little more tired and cranky. He is also teething though, can see he has lost about 4 teeth in last 2 weeks. Could it be an allergy? We haven't changed food or treats in the past 3 days...

Hi there. Sneezing could be caused by allergies, or an upper respiratory infection. If he's acting fairly normal otherwise (eating and drinking fine, active, etc.) you could opt to monitor him for now and see how things go for the next few days. The problem may resolve on its own, similar to when we get a minor cold or allergy flare-up. If there is no improvement in the next 2-3 days, or if your pup develops other symptoms such as coughing, thick green or yellow nasal discharge, or begins acting very lethargic or not eating, then I would recommend having him seen by a veterinarian for treatment.
