Hi Denise,
It was me. My vet said I could give them to Muffin and I did sometimes. She was close to Giz's size and I would usually give her just a half of one of the fruit-flavored chewables. She said I could give her a whole one if that wasn't sufficient. I'd just give it to her and she ate it like a kid would eat candy!

That should be right down Giz's alley!
I've been wondering how he was doing and hoping you'd give an update. Also, did you get moved?
