We haven't used them, but my understanding is that they are fine for a snack/treat (lo carb). But they say on the packaging that they are not a complete meal and shouldn't be used as such. The xanthium gum is their thickening agent rather than gluten.
Thank you. I want to give a treat because I am feeling guilty about leaving him alone for the weekend. This way, he can have a nice treat while I am gone.
Perfectly safe and fine to use as a treat. Kitty will thank you for it, I'm sure - also check out the freeze dried treats - such as halo liv a littles, purebites - cheapest is kingswholesale.com or primebites - pet smart (dog section).
