Katherine was spectacular! She introduced Rocky and Mountain to us and told us about their personalities. She took plenty of time to review their medical history and introduce us to their mom and dad. She had towels that she rubbed all over mom/dad that we then put in the carrier with them. Once we got home we sent her updates to show how the pups were adapting to their new home. Mountain who was a super shy boy came out of his shell within 24 hours and is now driving his brother Rocky crazy stealing his toys.
