Dogs, ear infections...

My pit ( Blazer ) is allergic to artificial fillers in certain dog foods, the food was causing ear infections. The poor dog would damn near tear his ears off scratching. The vet recommended we switch to all natural food with no fillers for his diet. Blazer is now free of any ear problems. It took too many years to find his problem.
I hope you can figure out what is causing your dogs misery.
