How could I forget Liver Biscotti? Those are our favorites!
Bananas are OK (mine get a slice every morning) but I'd skip the citrus (oranges, etc.) Apples are good. With mine carrots just tend to come out the other end. They LOVE green beans though. Peas and carrots are in their Merrick food so I'm sure that's OK. Potatoes too.
I sell all the commercial treats I listed on my website
