Sterling has been such a blessing to our family. I spent a lot of time researching breeders for our new addition. Libby met all my requirements; OFA certified, excellent conformation and excellent temperments.I was a little concerned about how shipping Sterling would go. I wasn't sure if he would be scared or if he was going to be soiled from the flight. No, we opened his crate at the airport, and he was perfect, and instantly we were MORE in love! Buying Sterling from Cornerstone also came with a new Cornerstone family that I check in with daily. We are a close-knit family, and I enjoy seeing all our pups grow and seeing the family expand. Libby has done a fantastic job with her program and an even better job getting her puppies ready to send home. Sterling is such a well-rounded puppy. He came to us knowing boundaries, crate trained, use to baths and basically potty trained. We love Sterling and Cornerstone so much that we will be adding a sibling for sterling in the next couple years.
