There's also an inflatable Kong Cloud Collar that's less intrusive. Our first dog had allergies; fleas, hay fever, wool.... most she grew out of.

Our current Lab has been itching for the first time since we got him (2-1/2 yrs), but we're not convinced it's allergies yet; so far he just seems to have dry skin, so we're trying some shampoos first. The first one worked, but only for a few days.
