Why Your Dog Smells Like Sour Milk

It can be quite concerning when your dog’s body suddenly smells of something bad such as sour milk. Here are the most common reasons why your dog may have a rancid smell. Some of the causes may require immediate vet attention so be sure to contact your vet for consultation if you aren’t certain.

Your Dog Has an Infection

The sour milk smell from your dog’s body could be due to an infection. One painful condition that could lead to this is urinary tract infection. Your dog could be licking himself constantly and the smell of the urinary infection could be lingering from the dog’s mouth.

Urinary tract infection, however, isn’t the only type of infection that may cause the sour milk smell. It could also be due to things like yeast infection, which you will know of if your dog starts to scratch himself constantly. In such cases, it’s important to get your dog checked out before the condition potentially worsens.

Smell from the Dog’s Collar

When was the last time you washed the dog’s collar? Some people forget that the bad odor can also come from accessories like dog collars and harnesses, especially when these accessories get damp. Don’t forget to wash these accessories regularly. Washing the collar with home ingredients like vinegar for example could make it smell nicer.

Your Dog Has Anal Gland Issues

The sour milk smell could also be coming from your dog’s anal glands. These glands are located on both sides of the dog’s rectums. Some dogs have trouble expressing (emptying) the anal glands on their own so may need some help from us to get them properly expressed from time to time. The fluid is usually watery in consistency and have a yellow tan color. Expressing the anal glands may help eliminate the sour milk smell from your dog.
