Sarah was very helpful and always sent us pictures of our puppy’s progress. I would not hesitate to get another. Our new family member is loving her new home. Thank you for the happiness and joy for years to come!

My experience was great with Sarah! This was our first time getting a dog from a breeder, especially an out of state breeder. She walked me through the whole process. She helped me with what we will need for the flight, paperwork, and answered all my questions kindly. She sent me pictures of my dog weekly and sent me updates on his vet visits and other information. My husband flew to Texas to meet her and get the puppy and said she was the nicest person and they had a good time connecting. While I was back home waiting for my husband and new pup to arrive she was sending us videos and pictures of the puppy traveling to the airport and getting to the airport. I cannot say enough good things about Sarah and our amazing puppy she gave to us. She has honestly become an extended member of our family. The best first experience on this app and first time getting a dog! Thank you Sarah!!! We will gladly fly to Texas again to pick up another pup down the road for us or family members looking for a great border collie!!
