I happened upon this thread while looking to see what others thought about the Canidae grain-free kibble. Like SO many dog owners, I'd had my 2 dogs on Canidae for over 5 years, and when they changed the formula I was not happy about it at all. Both dogs ate it okay, but had very loose poo for about a week, and then very yellow poo for good.. and LOTS of it!
I've always alternated them about every 3 bags to another quality food, just for some variety, but had always liked Canidae the best for their main food. When I heard they were coming out with the grain-free formula I decided to try a bag once the pet store I buy my food got it in. My dogs love the grain-free formula... and the poo is back to "normal" and MUCH less volume!
I also had a former foster dog returned to me about a month ago that had skin issues, and had been on Kirkland Lamb & Rice (and told any other food caused skin problems) but I switched him "cold turkey" since I was not given any of his food when he came back, and he has not had a bit of trouble with the switch to the grain-free Canidae from day one. I'm very pleased with this formula... and most likely will still use this formula as my "main" kibble... but I am still very disappointed in what Canidae pulled with the formula change on their other formulas... shame on them!
