I didn't know dogs could eat cheerios. Lol. I'll have to remember that next time I go shopping.
I've never cooked for my dogs, but I've spent extra time preparing meals or treats. Crushing up a couple of eggs, etc. Which I never actually noticed how much shells stick together when raw...took me ages to get them to break up into smaller pieces. Mind you, I was using a potato masher, maybe I haven't found the right method yet.
There's recipes for making kibble cakes for dogs too, I was entertaining on making them one for their birthdays last year, as they share the same birth-week. Didn't actually do it though, as I was a bit worried in using up all that kibble...
