Loki is on Canidae and we love it. Had had diarrhea issues until I put him on the Canidae at about 10 months old and he hasn't had a bout of it since (he's over a year and a half now). His trainer told me about Canidae and how it has pro-biotics and Omega 3 in it. She also introduced me to WDJ. I've giving him a few pieces of some samples of some of the other good foods and he is just really happy with his Canidae. He scarfs it and his coat looks great on it. And he can eat treats now that would make him sick before.
I always have it in the back of my head that I should switch if there is anything better out there, or that I should rotate or mix foods, and each time I try he pukes or does something to remind me he likes his Canidae best! My husband gets mad if I bring a new food home because of everything we went through to find the Canidae in the first place. So we stick with it. I just give Loki "extras" like eggs and chicken and a green bean or piece of banana once in a while to satisfy my "variety" urges. He's happy to eat the yummy kibble.
I buy Bully Sticks from Merrick and I'm always tempted by their food, but it's SO pricey compared to my $6/bag Canidae and the ingredients look similar. I tried Innova and Wellness before we found Canidae and did not have luck with either. He LOVED the evo but it made him sick. The others he did not like.
