I use my friends all the time to help build confidence or work through a tough situation. It only seems fair to give Izzy the same resource. Best friend cocked an eyebrow at me the other day as she waited for me to ask her to stand in the scary corner. Izzy knows her as his human "goat" so it only makes sense that she could help him too.
I haven't asked her yet, but she's ready for it. After all, that's what friends are for!
