Thanks for all the great suggestions! I'm signing up for that Yorkie play date chapter thing...I'm really excited! I didn't know dogs could eat people food! I'll invest in some carrots and apples. He could use the extra veggies and stuff since his food is very high protein. It's regular dog food...he's WAY past the puppy stage.
I'll start doing some research on what other kinds of fresh food dogs can eat. I think he might really get into that! He's always under my feet when I'm cooking, hoping to catch a nibble. LOL.
