Does anyone feed their dog(s) on Chudleys original?

I've just opened a sack for my dogs seeing as it's what my puppy ate when he first came to us and his breeder said he did well on it. However, even after 10 days of slowly mixing it in, it's just giving him a poorly tummy. I'm going to have to give it up as a bad job now so if anyone could use the sack (best part of 15kg), you're welcome to it.

Thanks

Is that your dog in your avater/ and is he/she a sammy??
Led to believe that they can be intolerent of gluten.

The main ingredient of chudleys original is wheat, and overall, has a higher cereal/lower protien contant than their other feeds. Our dogs are fed chudleys working crunch, of which the main ingredient is chicken and overall less cereal content and had no problems with any of our dogs with it.
you could maybe donate it to one of the rescue centres, sure they would gratefully accept it :)
