If your house smells like wet dog, it could be due to a number of factors. Here are some common causes of a wet dog smell in the home and how to address them:

1. Wet dog smell in carpet or upholstery: If your dog has been playing outside in the rain or has gotten into a puddle, they may track water and mud into the house on their fur. This can lead to a wet dog smell in your carpet or upholstery. To remove the smell, try using a carpet cleaner or an upholstery cleaner specifically designed to remove pet odors. You may also want to consider using a dehumidifier to help remove excess moisture from the air, which can prevent the smell from returning.
2. Wet dog smell in your dog’s bed: If your dog’s bed smells like wet dog, it may be because it is not being laundered often enough. Dogs can sweat through their paws, which can lead to a wet dog smell on their bedding. To prevent this, be sure to wash your dog’s bedding at least once a week, or more often if it starts to smell.
3. Wet dog smell in the laundry: If your laundry room or clothes smell like wet dog, it could be because your dog has been sleeping on your laundry or because you are washing your dog’s bedding with your own clothes. To prevent this, be sure to keep your dog off of your laundry and wash your dog’s bedding separately.
4. Wet dog smell in the air: If you can’t pinpoint the source of the wet dog smell in your home, it could be that the smell is simply in the air. This can happen if your dog has been outside in the rain or if there is high humidity in your home. To remove the smell from the air, try using a commercial odor eliminator or making your own natural air freshener using essential oils. You may also want to use a dehumidifier to help reduce excess moisture in the air.

In conclusion, a wet dog smell in your home can be caused by a number of factors, including wet or muddy dogs tracking in water, dirty dog bedding, wet laundry, or high humidity in the air. To eliminate the smell, be sure to clean any affected areas, wash your dog’s bedding regularly, and use a dehumidifier to help reduce excess moisture in the air.
