Other Causes of Cheesy Smelling Breath in Dogs
Here, you’ll find some of the most common reasons a dog’s breath may smell like cheese:
Toxic plants: dogs are famous for eating just about anything that attracts their attention, which can include plants in the house or in the garden. Dogs are not discerning when it comes to eating plants. They sometimes choose to eat plants that are toxic to them. Some plants may cause a dog’s breath to smell rancid, cheesy, or yeasty.
Yeast infection: can cause a dog’s breath to smell cheesy or rancid. The yeast may be in your dog’s mouth or system or even on his skin. As with other infections, a yeast infection can become serious if left untreated.
Allergic reaction: dogs that are having an allergic reaction may also have breath that smells like cheese or yeast. The allergies can be environmental or seasonal, and even food-related. Just like an infection, an underlying allergy needs to be treated, or it can become worse.
