Ddog has been bitten around both eyes - by midges, we think. She's developed blister-like swellings that have reduced quite a lot when we put a cold, wet towel on them, but I'd like to be able to prevent it happening again, so I was wondering if there are any insect repellents that are safe for use on dogs. I wouldn't put it too close to her eyes, but was hoping that if it was on her head, it might stop the midgies biting her.
