About Archie
Archie is adorable little Man (Little Big Man) he gets along well with all the other dogs, he’s not too sure about the Cat. He loves to run and play with the other dogs on our forest hikes but when he decides he’s done and it’s time to head back to the house he does. He is great with the puppies very interested in the newborns.

We had a great experience bringing home a puppy from Theresa. She was always polite and super communicative and had answers to all our questions. We are so happy with our Bella pup!

We received little Ollie (Florida Man) on Sept. 13, 2024. Theresa must have spent a lot of time with him since it only took a day or two to potty train him. She was wonderful to work with and was there to answer all our questions. Her kindness must have rubbed off on Ollie because he is kind and responsive just like her. Thank you so much Theresa for this wonderful gift of Ollie.

Theresa is wonderful! She always responded quickly, and was great with communication. It is obvious she really cares about her puppies. She sent us with everything we needed to be prepared and help with the transition for Clyde’s new home. We couldn’t be any happier or love Clyde anymore than we do! ♥️

Working with Theresa was a breeze. She was communicative, helpful, and made picking up our new girl a smooth experience. Our girl came sweet with an already amazing temperament. She has fit right in with our pack, and we would definitely love to work with her again.
