Our 12 yo lab/pit mix is having side affects from the use of NexGard Flea and Tick treatment. He is in very good health as a rule . He had a vet check about a month ago. All was fine. Since giving him the flea mess we have noticed a loss of appetite, lethargy and dry flaky skin. This is by no means the norm for our baby. How long will this last? Are there any natural alternatives for flea and tick control. Seeing our dog like this is heartbreaking ...
