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.
Most ear infections in adults are caused by bacteria and yeast, though ear mites are a common cause in puppies. Your veterinarian will take a sample from the affected ear(s) and examine it under the microscope to help identify what microorganisms are present.
