CC doesn't use carrageenan in their canned foods anymore!
Instead, they use guar gum...good source of fiber. They need to update it on their site, not sure if they did yet? Another reason their email is not working, not sure why it's taking them so long to revamp it...I stopped emailing them, never heard a response.
Mine are eating grain free Wilderness venison (b4 they were eating Open Sky duck) for dinner only & they eat it w/out any toppers like they're starving loll. They don't get any kind of treats whatsoever, so they have a good appetite @ mealtimes. I do squirt a little bit of fish oil w/omega 3 on it. It stinks, but it has so many good benefits & they love it!
Just curious why you chose chicken, since chicken is not a novel protein & some dogs are allergic to it...if it is food related?
