I am happy with finding a good breeder on Good dog. Phyllis took very good care of the puppy and had a lot of information on the corgis. I named my little girl Iris. She is very good and fast learner and smart.

Koda is great. Phyllis was so helpful with preparing me. The puppy is happy and friendly. The cat and Koda have become play buddies. I appreciate getting my puppy from such a wonderful lady.

I picked up my pup 2 weeks ago. The vet says she is healthy and beautiful. She has a great personality and I have been very happy with my experience. Phyllis made the process easy, answered all my questions and made sure I was set for the first week with food and a blanket.

Phyllis from Sierrita Mountain corgis provided such a fantastic experience for our family from the very beginning. Phyllis provided time to meet our corgi, which gave us a good bonding time before she was ready to come home with us. Phyllis responded quickly with updates and cute photo's of our Shelby! Phyllis provided important information about the corgi breed and many tips of how best to provide the best care for Shelby, we truly appreciate her knowledge and experience!

Our Tri-Color is a beautiful girl! The breeder was kind, responsive, communicative, and took good care of the pups. She set us up with some supplies to get started and made sure our little girl had a bath before we picked her up. We are so glad we found out little girl with Sierrita Mountain Corgis!
