Sounds to me like you handled it well and that it's just a learning experience for Reesie. Pups have to be taught just like children. I have a 5 year old and an 8 year old and two Yorkies. Tucket is 6 months old but when he was younger, he did the same thing. We just had to teach him that that's not ok. My boys are also VERY careful and loving toward the dogs so I know it was just a pup thing.
