Every year at about this time, when the summer turns hot and humid, our dog (a black lab/border collie mix who looks mostly like a lab) starts itching all over almost non-stop and licking/biting anywhere she can reach but mostly her front legs. In the past, only prednisone has provided her with relief. Last winter though we almost lost her to liver failure. She recovered amazingly well and has been on an-all natural diet vet-approved diet ever since.

Because of the switch to all-natural, we were really hoping she could avoid the problem this year, but no such luck. Because of her liver issue, the vet does not want to treat her with steriods and thus she is only getting Benadryl. This helps only a little and she still is in a lot of discomfort. The vet also suggested a topical spray for hot-spots, but really, she itches all over and that might only help with her legs.

Any other ideas?
