Why does my dog smell bad again quickly after a bath? Is it yeast?

Updated On September 23rd, 2025

Pet's info: Dog | Dogue de Bordeaux | Female | unspayed | 5 years and 1 month old | 97 lbs

Any advice on smelly dogs? Bella is a French bull mastiff, she gets a bath usually twice a week because of her horrible odor, once I bath her, she smells alright for about a day and a half, and then right back to smelling bad. I want her to remain an inside dog, just don't want a house that smells like dirty dog. Any advice would be awesome!!

One of the most common reasons that dogs will produce a "doggy odor" quickly right after a bath is if they have an overgrowth of a normal yeast on their skin called malessezia. This is more common in dogs that have skin problems or allergies, but is very common in mastiffs. Often, the first place you start to notice the smell is the face because yeast loves the moisture of the eyes and mouth, so it will often start to overgrow there first. There are a number of prescriptions antifungal shampoos that you could use as well as wipes that you can use for the face. A non-prescription option might be to use Zymox shampoo which can help prevent yeast from regrowing as quickly after a bath. https://www.zymox.com/zymox-shampoo-itchy-inflamed-skin-12-oz If that does not seem to help or Bella becomes itchy, then I would certainly have your veterinarian evaluate her skin for a recommendation. Good luck! I hope that was helpful. Thanks for using PetCoach.
