Veterinary experts rate Zenrelia
“Zenrelia will benefit the owners of dogs with atopic dermatitis because they're going to be much less itchy. They're also only going to need to give medication once a day and that makes it simple to prescribe. I would absolutely prescribe Zenrelia myself and if my dog was itchy I would use it on my dog.”
