I’m receiving an error message that does not correspond with what I see on my screen here. I don’t *think* this is a duplicate post, but a technical malfunction. (Please pardon me if it is.)

Nadia,

The only guidance I’ve ever received or read from trustworthy experts in diagnosing and treating dog food allergies is a food trial:

*Novel protein diet for up to 12 weeks (or other hypoallergenic test diet, like hydrolyzed) to evaluate for relief
*Followed by challenging testing the dog with one single food at a time, a former/suspected ingredient allergen

I’ve been there, with a very itchy dog with food and other allergies. And the above is the route I’ve followed, with a primary care vet and boarded specialist. We also did things to exclude other diagnoses. That’s what I would recommend.

I’ve heard (and read here) of others referencing blood tests, saliva tests, hair tests, etc. But to the best of my knowledge, there is not medical evidence to support their efficacy and they are not the standard of care in the medical community.

I worry that such tests not only scam well-meaning pet owners out of money (which they could use otherwise to help their pets), but also lead people to come up with long lists of ingredients that their dogs are supposedly allergic to such that diet choices become severely limited. (IMO, it is very unlikely that these dogs are allergic to numerous and very uncommon things, things that the dog has never been exposed to.)

Re fleas, allergy or standard reactions to them are more common than are food allergies. (Inhalant and environmental allergies also are common culprits for itching.)

Vacuum, vacuum, vacuum. It will eliminate a lot of flea problems. Flea dirt is more likely to be discovered than fleas and fleas spend more of their life cycle off the dog in its environment than on. Vacuuming will also help keep pollen, irritants lower inside (as will removing shoes, etc.)
