I'm Aaron R., the breeder behind Legacy Retriever Project located in Golden, CO. We’re breeding Goldens with a rare gene variant associated with longevity. Your pup may be slender. We’ve studied canine genetics and consulted experts and the scientific evidence supports our theory. I’ll ask for occasional health updates — your dog is part of something meaningful!“.

We’re selectively breeding for a gene variant that produces lower levels of a hormone called IGF-1. In dogs, lower IGF-1 is associated with longer lifespan. Most large breeds carry the version of this gene that produces more IGF-1 — but a small number of Goldens still carry the ancestral “small” variant, and that’s what I’m working with. Your puppy has one or two copies of this variant. I’m tracking the health and longevity of dogs from this program over their lifetimes to see if it makes a meaningful difference. What this means for you: ∙ Your dog may be slender. ∙ I’ll ask you to share health updates over the years — this data is the whole point of the project I have studied canine genetics extensively and have consulted with experts in both genetics and veterinary medicine to design this program carefully. The science behind it is real and well-established in canine genetics research. You may just be giving a longer, healthier life to your dog — and helping prove it for future dogs too.

Exciting things happening behind the scenes at Legacy. We’re thrilled to be collaborating with Lauren from Co Pilot Golden Retrievers! Lauren’s puppies have jaw dropping genetic diversity, we’re so impressed that we’re bringing one of her puppies home soon! Lauren ALSO found our unicorn sire, who has a very specific genotype that we’re trying to preserve. Amazingly , she didn’t need to look far because he was born in her program last year! We’re so happy to have another breeder join us in our mission to find the path to brighter futures for Golden Retrievers ⭐️ https://www.gooddog.com/breeders/copilot-golden-retrievers-colorado

Pups started ENS and ESI today, then took a well deserved nap. ENS protocols require being disciplined and consistent but the benefits last their whole lives!

We’re very excited about this special litter! Parents were selected for excellent pet temperament and genetic expression of IGF1 regulation. Puppies have genetic haplotype that research shows are linked to longer lifespans. Research suggests inheriting even one copy shows intermediate effects. https://pmc.ncbi.nlm.nih.gov/articles/PMC3168604/#Fig1 https://pmc.ncbi.nlm.nih.gov/articles/PMC2789551/

About Lucy
Lucy is the best girl! Athletic but has an “off switch.” She’s always down for a swim or game of fetch but settles down indoors. She LOVES kids! Her specific variant of the IGF1 gene, often referred to as the "small dog haplotype“ is uncommon among Golden Retrievers and is associated with longevity.
Good health testing
Legacy Retriever Project reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Golden Retrievers.
Full Embark Panel, PRA, Rod-Cone Degeneration (PRA-prcd), Degenerative Myelopathy (DM; SOD1A), DNA Disease Panel, Ichthyosis, Golden Retriever Type, Neuronal Ceroid Lipofuscinosis 5 (NCL5), Golden Retriever Type, PRA, Golden Retriever 2, PRA, Golden Retriever 1
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).

Aaron and Stephanie were amazing to work with from start to finish. They were always willing to answer any of my questions no matter how big or small. You could really tell how much care they take with each of their litters in making sure they are practicing safe, ethical breeding and also making sure each family is the right fit for their puppies. We would love to work with them again and would recommend them to anyone looking for a forever fur baby.

Aaron and Stephanie are awesome. They are so great at communication and shared photos and videos throughout the process so we felt like we already knew our pup. We did a meet and greet day to pick and cuddle and it was awesome. These folks really love dogs and care about giving them a healthy and happy start!! Pup had all the first steps for potty and crate training on pick up day. He is a doll!

I knew immediately that Legacy Retriever Project would be the perfect breeder for us because of their knowledge of Goldens, genetic testing, and what factors go into breeding a healthy dog. They communicated everything throughout the process and were so knowledgeable about everything they did during Lucy’s pregnancy, the birth, whelping, and early puppy training and socialization. All 11 puppies were gorgeous and healthy. We are thrilled with our puppy and cannot believe the care and thoughtfulness their whole family put into the puppies and Lucy. We loved that there was another older female dog who helped the mom care for her puppies. We would have loved any one of the puppies in this litter. This is my fourth Golden Retriever and after just two full days with our puppy I can see a huge difference in this puppy compared to our previous Goldens. I think the early neuro sensitivity training and Puppy Culture philosophy makes a huge difference and I’m so grateful full Legacy made the effort to do this work.

Great communication from Aaron and Stephanie throughout the whole process. Highly recommend working with them to get yourself a great pup. We are so grateful for our little guy. Looking forward to litter group meet ups down the road!

Aaron and Stephanie with Legacy Retriever project were amazing to be in contact with during the process of bringing our new puppy home. They were so easy to talk to and were transparent about everything. I was so eager to be with my puppy before bringing him home and they were super flexible with allowing me to come see him multiple times. The amount of love they have raised with these puppies is evident. Not only did they provide excellent care to these puppies but what they are trying to do here with the Legacy Retriever project is amazing and inspiring. If you are considering getting a golden retriever, these are your people!

We brought home our golden puppy, Doppler, a few months ago and we couldn't have asked for a better dog or better breeders. Aaron and his wife, Stephanie, were FANTASTIC! Both were super responsive and answered all our questions. We got to meet Doppler several times before we took her home which made a big difference I think. Doppler has been a fantastic addition to our family. She gets along great with our older dog, 2 kids (4 & 7), and cat. She's healthy, playful, and loves everyone. She does like to eat the deer poop, which is hella gross, but no dog is perfect. =) Overall I would highly recommend! Also, Lucy is a beautiful dog and fantastic mom.
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
