Julie 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.
Julie 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.

“Jack Russell Puppies meet JRTCA guidelines. Your pup will go home after being vet checked, wormed, vaccinated, and microchipped. Reservation Fees are accepted only after a litter is born and we can determine we have a puppy for your family to reserve.”
Julie 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 Julie 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 Julie 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 Julie.

Milo and Maybe's litter

Julie D.
Let's call this ground Zero. Over the last few days, Milo and Maybe were allowed to breed. Trust me, breeding is never forced. Ethical breeders control when and which dogs are allowed to breed. During the first weeks after breeding, I like to watch mammary development to guess if my girls have settled into a pregnancy. On my Facebook page, I bring my followers along for the journey with weekly booby pictures so they can play the game, too. In about a month, I will bring Maybe to the vet for an ultrasound. This procedure will confirm if she is pregnant and, if we are lucky, will give us a general nose count of how many pups we will be expecting. Sorry, we won't be able to tell the sexes of pups. Pregnancy lasts right around two months. So, let the anticipation for this hopeful litter begin. :)

The South Coast Jack Russell Terrier Club is a JRTCA affiliate club. I am an active member serving as the Club's vice president for the next 2 years. We would love it if you were able to join us at our Fun Days or come to our annual trial. There are so many dogs to see and an amazing group of JRT people to connect with. We offer clinics on racing and go to ground. This weekend, we will also have a Brush Hunt Clinic.

About Milo
Milo is just a handsome studly dude. He approaches every task I ask of him, like a pro. He lives part-time with my ex-husband. Milo loves racing, go to ground, and super earth competitions. If you are one of his favorite people, he definitely lets you know with his barky, happy dance.

Julie could not have been more responsive! It was a joy working with her to meet up, talk, and fly home with my amazing puppy. Ollie came to me comfortable with his carrier, kennel, potty training, and an eagerness to learn.

I would highly recommend if anyone is looking for a JRT breed, to get in touch with Julie! She truly loves all her doggies and takes wonderful care of them!
