Can anyone help me with an issue that my Pembroke has? He just can't stop itching his ears/face. We currently have him in a Comfy Cone when we can't watch him to make sure he's not scratching. Per the vet he's on Benadryl 2x a day for allergies. I have noticed the itching is worse for him when my allergies are worse, could it be allergies? I just had him at the vet, who didn't find any issues with his ears.
