I went to the store to buy icecube trays and can food that's suitable for the trays, and ended up finding another great product for small dogs. It's
like this. Basically, small servings of pet food in small pouches. It's probably good for two servings for the little Yorkie, and if I open it and the second serving spoils before I use it, I guess it's not as big a deal.
I'm glad I found this and bought 24 pouches because interesting pet stuff like this are hard to come by where I live.
Thanks for all the advice everyone,
