1. Stewarts Freeze Dried Liver Treats and - 2. Cod Skins - have worked awesome w/us. The Cod Skins (warning) are puppy crack The brand I get is PolkaDog. If you sign up on their site, they may send some promo-codes…I just got one for free shipping (way too good to pass up) as they were just marked up and additional $4.50 at the boutique I found them in (a total of $18.50 for the small container) I'm all about supporting local businesses…but YIGES, that was quite an increase.Also how about treats? What are some good chicken, grain & potato free treats? Thanks!
