This is a dog (or cat) treat recipe. Although you could eat it - I guess.
Ice cube tray or silicon candy tray
yogurt (I used Greek style)
anything your dog likes to eat - I've used frozen vegetables and kibble.
Press salmon into the bottom of each compartment. Layer yogurt on top and freeze until solid. Remove from tray and put in a zip-loc bag. Keep frozen.
When I want to keep Tibby busy I give her one of these. They don't last as long as a frozen Kong, but they are pre-made, so I don't have to remember to stuff and freeze her Kong.
Tibby likes them!
