I just took my retriever Sniper to the vet for a swollen cheek. The vet has him on antibiotic and prednisone. Hopefully, this will take care of the problem. Interestingly, the dog also has small sores on his ear tips that we are treating, too. He does shake his head a bit. His dog food is Dr. Tim's grain free, chicken based. The cheek infection is not yet in need of a surgical draining. Any input would be gladly accepted.
