My puppy is sneezing, coughing, runny nose, and snoring. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | West Highland White Terrier | Male | unneutered | 3 months and 1 day old | 3.7 lbs

My puppy started sneezing more than usual 2 days ago (maybe 5 times a day). He has a little bit runny nose and coughs sometimes (especially after sleeping). He snored the night before last. He is still active and has a good appetite. Do you know what might be causing it and how serious is it likely to be? Attaching the photo of his face after sleeping (clearly something dropped off his nose during the night)

Poor Julian! Dogs can get respiratory illnesses and allergies, both of which can cause sneezing, coughing, and discharge like you've seen. In the case of infections, the discharge may become cloudy or yellow/green, whereas allergies tend to stay clear. In either case, since this has been ongoing a few days, it's a good idea to bring Julian into your vet. They can provide allergy medications or other treatments as needed depending on the cause. If you notice him worsening, the discharge changing color, fever, or changes in behavior or appetite, that's a sign that he needs to be seen sooner. Until then, keeping his eyes and nose clear with a clean washcloth can help keep him comfortable and prevent any debris from getting stuck and crusting his nostrils or eyes shut. Keeping him eating and drinking and in an area free of dust and dander can also help.
