Pengepuppy

Bought a packet of Wainwright's Grain Free Puppy biscuit bone hypo allergenic treats from Pets at Home fir my 16wk staffador. She likes them well enough but they do not agree with her digestion at all, causing terribly stinky farts and diarrhoea 24 hrs after using them for training sessions. We've given her a wide range of off-the-shelf treats and she's never had this problem. There don't seem to be any nasty ingredients in them and I can understand how the Beet extract would cause wind perhaps but the runny stool isn't fun.
