Where do your breeding dogs live?
Angela has been certified by Good Dog’s screening team for responsible and trusted breeding practices. When you’re ready to reach out, feel free to ask any questions about the breed, their program, or specific puppies.
Angela partners with buyers to find the best match as the puppies develop and their personalities take shape. Typically, matches are finalized when the puppies reach about 8 weeks old.
“We try and match each puppy with the correct family based on personality traits and needs of each family and puppy. This is done by assessing the strengths and weaknesses of each puppy and fitting them into the right family. As always socialization is key to this breed, and it is expected each family focuses on that aspect according to age-appropriate expectations. ”

“All puppies are the same regardless of color or sex. All puppies are sold on a limited AKC registration unless a different agreement has been reached.”
Angela may provide a written contract or health guarantee when you purchase a puppy. This helps protect both you and your breeder, ensuring that you both have a clear understanding of the terms of your puppy purchase. If Angela offers a contract or guarantee, the details will be personalized by them. If you have any questions or want to know more, don’t hesitate to reach out to Angela directly.
You can drive or fly to pick up your puppy from Angela.
