About Us

Tony and Eileen Coronado lived in Romoland, California since 1984.  In October 2006, we moved to our new ranch in Deer Park, Washington in October 2006.  It was a ‘Noah’s Arc’ experience without the water (7 horses, 13 dogs, 2 cats, 2 fish, and a tortoise!). 

In 2009 we moved back to California.  Currently, we live in Nuevo,CA. We can be reached by email or phone.  My cell phone number is 951-663-2976 & land line 951-325-7958. Cells are not dependable in our area, however, text go through when calls do not,  but the landline works great.


Eileen and Emily

In all our years together, we strive  to breed  top quality Australian Shepherd dogs and American Quarter Horses.  The Australian shepherds have been in Eileen’s family as long as she can remember.   Here is a picture of Eileen and her Aussie Emily dressed up for the Norco parade, Sept. 1964. Poor Em she sure took a lot from me as a kid. 

The Aussies have always been the versatile, beautiful, loyal companions, dependable babysitters, and great ranch dogs that have made this breed so popular today. The rest of the world is just finding out what we’ve known for years. Australian shepherds are wonderful dogs, no others are so versatile, loyal and loving!  

 Aussies excel in agility, herding, conformation, obedience, tracking, scent work and just being your best friend. We’ve even done Search and Rescue with one of our boys, Gorgeous. He was ready for certification testing in less than 3 mos. compared to the normal 9 mos. of training, and accepted and “hit” upon cadaver scenting.

Our bloodlines are strong and sound. We do not breed any dog whose hips rates less than OFA (Orthopedic Foundation for Animals)  Good and Elbows Normal. We are very selective when breeding to outside dogs due to the issues of genetic eye soundness and of course the issues of epilepsy and other prevalent genetic diseases now sadly permeated in this wonderful breed. Our dogs eyes are cleared yearly and puppies at 7 weeks of age by veterinary Ophthalmologist, we have tested every puppy, and every adult since the early 1990’s and have never had a dog diagnosed with CEA, PRA, PRCD which means we do not have any of these eye diseases in our bloodlines, past and present. Now we do genetic testing for HSF4 (hereditary eye cataracts), DM (Canine Degenerative Myelopathy),  and MDR1 (Multi Drug Sensitivity) testing. There is proof that even if a dog tests N/N (which means they do not have that gene for that condition in their body), for MDR1 it can still have a severe reaction to Ivermectin products and other sensitive items such as drugs used for anesthetizing. I do test the parents for MDR1 which will let us know if any pups could be carriers. None should be afflicted as we would not knowingly breed a carrier to a carrier. However even if the dogs are cleared (N/N) in this test it gives a false sense of security thinking their Aussie (or any merle gene dog) is safe to administer Ivermectin products such as heartworm meds, and some anesthetic drugs when in fact it may not be and the dog could still be in danger.  Always remind your veterinarian that this is an Aussie and to use extreme caution when administering drugs to  it. That being said, we do our best to ensure our dogs are as genetically sound and free of genetic diseases and conditions as possible.

Side note: for years (1990’s) horse people dewormed their horses with Ivermectin, it was a miracle drug at that time, it is currently ineffective as a wormer. We found that if Aussies and other merle gene dogs, somehow ingested any of the Ivermectin or horse manure (yes dogs love horse poop) from a newly dewormed horse, dogs were dropping dead, having neurological issues resulting in seizures and sometimes permanent damage from the effects of the drug. Most of us just used common sense and did our best to keep the dogs away from Ivermectin and the horses that ingested it for 48 hours. There was no name for this condition until the last few years, the gene has been identified and labeled MDR1.

Australian shepherds are beautifully colored with a wide variety of  patterns that never get repeated. We have all four colors, reds, blacks, red merles and blue merles. Eyes can be any pattern from blue (marbled, halves, striped, and dotted) to brown, green or amber. We even produce blue eyed tri’s and bi’s.

Our Aussie’s temperaments are an added bonus. They are loving, protective and willing to please. Their intelligence is astounding. The more you teach them, the more they want to learn. Their sense of humor is a trait that is an extra bonus, they love to make us laugh and especially seem to know when we need cheering up. Their grins are infectious and a total joy to come home too, they make us feel we are the most important person in the world. We are, in their world.

We are always glad to introduce people to the wonderful world of Aussies. If you’re ever in the area, stop by for a visit.

Our Quarter horses are also a very important part of our family. They too have been in our lives for many years. The bloodlines our horses carry are dependable working lines, with some excellent racing lines bred into them for speed and endurance. These horses and their ancestors have been with us for the last forty + years. Their overall health and correctness and strong breeding has given them long, healthy, useful lives. Of course, quarter horses come in all colors, however, because our stallion Tig is a dun who produces beautiful duns and buckskins, we get them mostly. Its a color that is very pleasing to the eye. These horses make great arena horses whether it’s pleasure, reining, cow horse or rodeo events.  As with our dogs, temperament is extremely important to us. Doesn’t matter how good looking or athletic an animal is, if its temperament is not willing to try and do whatever it is we need it to do, to please its owner, handler, rider, then we would be fighting an uphill battle most of the time. Trainers will tell you, if an animal isn’t willing, biddable (means to please) it makes the job of training extra hard. Both our horses and our dogs come from very long bloodlines of people pleasing ancestors.  

If you’d like to visit us, the dogs and or the horses, give us a call, we are always glad to sit and talk Aussie or horses.
