My dog is scratching like crazy since I switched his diet, could it be the beef I’m feeding him?

Hi Cindy,

First off, I just wanted to say thanks for the great basic dog obedience video, it?s been a incredible help to me. Also, the spill-proof bowl I just purchased from you guys is an outstanding product, I highly recommend it to any dog owner.

My question though is about allergies. My almost 2 Y.O. working-line shepherd has been itching and scratching like mad for the last few months, and I can?t seem to find a remedy for it. From about 4 months on, I fed him half raw meat, half Innova EVO, and he never seemed to have any allergy issues. Then, after seeing a new product at a local pet food store, I switched him to ?SoJos,? 100% grain-free raw mix to supplement his raw meat (typically Beef). Is it possible he?s allergic to the Beef? The Sojos is human grade veggies, so I wouldn?t think that would be the culprit. Could it be an air-born allergen? ...any help at this point would be greatly appreciated, I REALLY don?t want to have the vet give him any more shots. (he hasn?t had any vaccinations since he was a little pup).

Thank you so much,

Brian
