Meet the breeder

I'm Madeline O., the breeder behind Old Hemp Border Collies / Open Horizon Sport Dogs located in Reno, NV. My number 1 goal in my program and dogs is stable temperaments that fit into today's world. Temperament is what affects us the most every day with dogs and is paramount to lifetime success. You can read in depth descriptions of all of my dogs on their respective pages, and find health results, etc.

Q. & A. with Madeline

  • Why did you start breeding?

    I had my first litter in 2017, but I've never stopped learning and bettering my practices to breed "perfect dogs" who fit in today's world, are versatile, healthy, affectionate, stable and sound. I have produced pups who have gone on to be task trained service dogs, therapy dogs, sport dogs, companions, herding dogs, and everything in between. I pride myself on having very happy puppy owners.
  • What makes your program special?

    I educate my puppy owners on all things dog. Nutrition, overall care like nail trims, teeth brushing, vaccines, spay/neuter, socialization, training, and how to properly advocate for your dog. How to be your dog's best friend and how to maintain a healthy relationship built on mutual understanding and clear communication. I support my pup's and their humans for the lifetime of the dog.
  • What are the different breed sizes in your program?

    Sporty Mix puppies include small and medium sizes. Sizes will vary depending on the parent dogs.
  • What are the different breed coat types in your program?

    Border Collie puppies include smooth and rough coat varieties. Coat types may vary depending on the parent dogs.
  • What are the different breed coat colors in your program?

    Our Papillon puppies include black red and white, black brown and white, white and sable, and white and black. Colors will vary depending on the parent dogs.
  • Where do your breeding dogs live?

    They live in my home and guardian homes.

    We brought home our Border Collie from Madeline in 2021, and we couldn’t be happier. From the start, Madeline was incredibly knowledgeable and supportive—always available to answer our questions and help guide us through the process. What truly set her apart was her ability to match us with the perfect dog for our family dynamic. We already had a small, sensitive terrier who needed a gentle and respectful companion, and Madeline delivered exactly that. The two dogs are now best friends and get along beautifully. Our Border Collie is everything we hoped for and more. He’s got the perfect balance of energy to keep up with our active lifestyle, but he also knows how to settle and relax when it’s time to wind down. He’s excelled in dock diving, and he loves barn hunt, herding, and agility. His excellent temperament and trainability have made public access outings a breeze. We highly recommend Madeline and her program. She is the definition of a responsible, ethical, and truly reputable breeder. Her thoughtful breeding and unmatched support have made all the difference for our family.

    In our quest to expand our whippet family, my husband had one request: the breeder should be conveniently located near our home. After extensive research and careful consideration, we found the ideal breeder, Old Hemp Border Collies/ Open Horizon Sport Dogs, only five states away! Madeline’s breeding program extends so far beyond puppy sales; she prioritizes total well being, exposure and stimulation to different environments and socialization insuring a balanced, highly functional and healthy companion for life. We could not have asked for more and given the chance would not hesitate to travel that distance again!

    I was dreaming of a Border Collie for years and stumbled upon Old Hemp Border Collies just as the Space litter was born. Instantly I was drawn to Solstice and watched her grow, waiting excitedly for updates. With a magic twist of fate, I was chosen to be Solstice's (now Gaia) new person! Madeline was awesome to work with, always patient and kind with all my "new mom" worries. She and Daniel did zoom meetings to help with training and helped ease us into puppy life. Madeline was always a text away and quick to respond. A couple years went by and I was ready for another BC. Madeline kept me in the loop from breeding to birth and up to selection of my next sweet boy Merino (now Flynn) from the Fabrics litter. Madeline and Daniel are the type of people you feel instantly friends with and like you can rely on them when dog problems arise to help trouble shoot and solve them so the dog you get from Old Hemp will be the best they can be.

    A little over 3 years ago I got my first puppy from Madeline, and it was easily one of the best decisions I have made. After I decided that I wanted a border collie, I started to look for ethical breeders online who health tested, used puppy culture, and had knowledge on the breed. Madeline was recommended to me by an online friend and after looking into her program, and seeing she was also a trainer, I knew I had to reach out. I ended up speaking with Madeline for almost a year before I put in my application for my first puppy. Madeline was, and always has been completely honest and open with me. She answers any and every question with transparent honesty and no judgment. She is very easy to approach and she is very knowledgeable about the breed. After putting in my application and going over what I was looking for in a dog, Madeline reached out and said she had picked out Mac and thought that he would be a great match for us. We made arrangements and drove down to meet Mac and Madeline for the first time and it was an unforgettable experience. Madeline welcomed us into her home, and introduced us to Mac and let us spend some time with Mac's dam as well as other dogs in her program. We brought Mac home and Madeline kept in close touch with us. She made it very clear that I could reach out anytime and she has to this day always been supportive. Mac is everything I asked for and more. He has grown into an amazing, stable, athletic border collie. He excels at disc and he earned his championship disc dog title after placing 3rd out of over 400 teams during his first season in the k9 disc league. Mac was such an amazing dog that we decided to get our next two from Madeline as well and they have also been absolutely amazing. I am beyond grateful that I have Madeline as a breeder and that I have the lovely dogs, that she carefully and lovingly produced, in my home. Madeline works hard and puts so much love and care into her program, and it shows in the dogs she produces. She doesn't just love them while they are there, she loves them for life. I am absolutely thrilled with my three OH dogs, Mac, Wick, and Feyre, and I love being a part of the OH family. Reach out to Madeline for your next dog! I promise you wouldn't regret it!

    I will never be able to thank Madeline enough for trusting with me with my first ever Whippet! Lurk (formerly Larimar) is the sweetest, most stable, and easy dog I’ve ever owned or trained. He’s an easy going guy who settled into my multi-dog household effortlessly. He was everything I was wanting and I’m forever grateful to call him mine. Madeline definitely knows her dogs and is very selective with breedings and puppy matching. Lurk has all the traits and attributes she said he would. Her ability to get to know each puppy results in them finding perfect owners. In my opinion Madeline is a great representation of an ethical breeder and plan to get more OH dogs in the future!

    We met Madeline through a mutual connection to border collies we already owned. As we started following her and watching her thoroughness with education and all her transparency with every breeding pair we decided to reach out and see about getting a new family member. She made the experience very comfortable and she is a great person. Three years later I continue to follow her and any time you have questions or concerns she’s always there to answer them. Just because you have had your pup a while doesn’t mean you lose touch with her. I have recommended her to others looking for a dog and have shared helpful information she’s given me as well. In a heartbeat I’d get another dog from her!
