How refreshing to see another grandparent here. There are several of us and I'm sure you will meet the rest soon.
I'm sorry about the loss of your Westie. I had a Westie years ago I named Bonnie. What a wonderful breed they are!
I too home cook for my three Yorkies. Been doing this for 48 years without any problems at all. I even fostered Yorkies for a few years and got all of them on real food as well.
Let us know all about your little fur-boy and we also love looking at pictures.
