Stop using bosutinib and call your doctor at once if you have: 1  severe or ongoing nausea, vomiting, stomach pain, or diarrhea; 2  black, bloody, or tarry stools, coughing up blood or vomit that looks like coffee grounds;  fever, chills, body aches, flu symptoms, sores in your mouth and throat;
Food (or environmental) allergies are especially likely to be implicated in ear problems when both ears are involved. An excess of grain and / or sugar in the diet is one of the most common causes of ear infections in dogs. The sugar actually feeds the yeast which lives naturally in the body and causes a yeast overgrowth, which results in the dark, yeasty-smelling buildup that can occur inside the ears.
That gives yeast a favorable environment in which to grow. If your dog swims or is bathed frequently, trapped water or debris in the ear canal can lead to yeast infections. Allergens like pollens, mold, dust, feathers, cigarette smoke, cleaning products, and certain foods can also lead to ear infections in a dog.
