Working with Summer made the process of finding our perfect pup an absolute dream! She kept us updated every step of the way, sharing details about the puppies and helping us choose our sweet little boy. Even though we live out of state, Summer made the transition seamless and arranged for our pup to be flown to us. I’m so grateful to have found Summer during this journey—it truly made all the difference!

Summer was awesome to deal with. She described our puppy perfectly. We feel like we won the lottery with our new girl. Temperament is perfect. I highly recommend her if you looking for a Berner.
