LooneyBoone, I had the exact same problem when I got a bag of Acana with grain. Normally I feed Acana grain free but got a bag of the other stuff cheap and regreted it. 2 of 4 dogs definitely had up-set stomachs. It seems to be an individual dog thing.
Patty, LOL I might just as well leave the vacuum on full time. There's even hair on the walls! Sa-neeze!
