What foods should dogs avoid with yeast infections?

Yeast infections in dogs can be tricky, so it’s essential to ensure your pup is eating foods that won’t exacerbate the problem. The most important thing to remember when feeding your pup food with a yeast infection is to avoid sugar and carbohydrates. Yeast infections feed off sugar and carbs, so eliminating them from the diet is essential. This prevents sweet treats like cookies, cakes, and other sugary snacks. It also means avoiding starches like rice, potatoes, and pasta. In addition to avoiding sugar and carbs, it’s essential to avoid foods with high yeast content. This includes bread, beer, and anything made with yeast or yeast extracts. Any food with high-fat content should also be avoided as it can be difficult for your pup to digest. Finally, ensuring your dog gets enough vitamins and minerals in its diet is vital. A balanced diet is key for keeping yeast infections at bay. Aim for foods high in essential vitamins and minerals like calcium, phosphorus, magnesium, and vitamin A.

What kills a yeast infection in dogs’ ears?

The vet may prescribe a topical antifungal cream or ointment and oral medications to help clear up the infection. You can also try home remedies to help treat the disease. Cleaning your dog’s ears regularly with a mild cleaning solution can help keep yeast infections at bay. Additionally, adding plain yogurt to your dog’s diet can help to restore the natural balance of bacteria in their gut and reduce the chances of yeast overgrowth. You can also use ingredients like apple cider vinegar and hydrogen peroxide to flush out the ears and reduce the amount of yeast. These solutions should be used with caution, though – make sure you dilute them with equal water before using them.
