We use Taste of the Wild as well - salmon. It's the only food Lou's ever eaten, and we've never had a problem with it. A couple of notes - if your dog has super bad allergies, talk to your vet about giving him Zyrtec (or the generic Allertec) every day....and Fish oil. Lou is 3.5 years old and we started him on fish oil about six months ago. he's been much healthier! I wish we would have know about that sooner.
Oh - and how old are your children? I'm writing a children's book about Lou, check out my blog. ( Square Dog Round World )We have coloring pages and fun questions for kids to answer to help figure out what Lou will do next.
Best of luck!
