My rescue dog has a sinus infection. Will it heal naturally?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 42 lbs

My new rescue dog, a 14mo old lab mix, has a possible sinus infection. we've only had her home about 4 days. (She spent Almost 2 weeks at the shelter.)Almost yellow drainage, almost blood tinged. She breathes easy when shes awake but sneezes a lot. Still eating/playing. I haven't owned a dog in almost 10 years, are dogs like humans? Will she get over this without antibiotics? We aren't into going to the doctor without it being what would seem to be more serios.

You can try some Benadryl twice a day to see if this helps. See link below. You can also put her in a small bathroom with a hot steamy shower going to allow the steam to help break up the mucus. If it isn't improving, then I would have your vet take a look at her. Unfortunately, a lot of dog end up needing antibiotics to help get rid of these upper respiratory infections. I hope this helps!
