I purchased two Jack Russell Terriers from Eli Zook. Both Puppies (Polly and Piper) are healthy active puppies. I took them to the vet for their shots and everything was good. They adjusted quickly and you can tell they spent a lot of time with human interaction and care. I was impressed as soon as arriving as they have a big open yard that was full of healthy, happy dogs running around. Even the mother of these 15 week old puppies was running around. They were professional and kind. Truly excellent people. I would recommend this breeder to everyone.
