I'm Irina S., the breeder behind Alta Concordia German Shepherds located in Worcester, MA. We've been involved in breeding and training German Shepherds since 1997. We are active in the dog sport IGP, the ultimate test of a working dog's character. All our dogs are health-tested, screened and cleared for genetic conditions (HD/ED/DM/etc.).

Irina has been certified by Good Dog’s screening team for responsible and trusted breeding practices. When you’re ready, reach out to ask about the puppies or anything else on your mind. You’ll get to know each other through messaging, phone, or video and pay securely, all on Good Dog.
Irina 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 match puppies with the buyers with the intent to place a right puppy in a right family. The temperaments are assessed around age of 7-8 weeks.”

“The price include deworming, DNA testing, initial vaccination, health exam, microchipping and USCA pedigree. All of our puppies are the same price, regardless of color, size, or time of the pick up.”
Irina 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 Irina 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 Irina directly.
When you pay and communicate on Good Dog, you’re covered by Payment Protection.
You can drive or fly to pick up your puppy from Irina.

A breeder may perform additional tests on their dogs that do not fall into these general categories. These tests may be more uncommon or very specific to a particular breed.

Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).
