Unfortunately our Zephyrus did not get pregnant again so we will have to decide our plans for her. We might use her in sports games for a while. We should have litters from Calypso and Artemis sometime this year but not sure of the time frame. We will probably skip mama Vesper's next heat and then breed her again after that.

This cute boy is available he has a super sweet personality.

About Zephyrus
Zephyrus was Nimbus' first pup and was a singleton, meaning a litter of one, so she got a lot of attention from her mom and our family. She is the first production of our kennel and so far she has exceeded our expectations. She is the daughter of our dog Nimbus of Superstes Guard and Coronado's Jack of Highline Kennels. Both her parents were Embark and OFA tested so she is our first baby and from fully health tested parents. She is embarked DNA tested and is clear for affecting conditions with one copy ALT. She is blue and carries chocolate and pied and she has light ticking. She is 20 inches tall with a 21.5 head and about 80 pounds weight. She is registered UKC and ABR and XLBC and ABA. She has a great loving friendly personality and loves everyone. She is spoiled and sleeps in my bed along with mom Nimbus. She has nice clean lines of conformation, with a short back , good legs and feet and an old school blue look. She was just in her first show. She has been OFA tested she is cardiac normal , and pennhip shows shows no evidence of oa and Her OFA testing came back Hips Good. This girl is very loving and is beautiful inside and out.

About Nimbus
Nimbus is a classic blue piebald with ticking and she is a tri-carrier. Her father / grandfather was an extreme piebald standard, and her mother was blue of xl height. Nimbus is 18" at the withers and is a classic American bully, her head is 20". She has a very clean conformation with a tuck and cat feet and she embark tested 100% American Bully and all clear. She is embark tested and clear of all genetic diseases and OFA tested for hips, heart, elbows and patellas. Her hips are fair, her heart is normal, her patellas are normal and one elbow is normal and the other is fair. She has a short muzzle AA. She is ABR and UKC single registered but both her Embark dna and ukc dna were provided to the registry so she is DNA P. She is micro chipped too. She just had her third litter and is now our retired pet in our home. She is single registered because her father was stolen from the breeder right after her birth and he chose not register them because of the home invasion and theft he did not want to breed anymore. I single registered her as she is the most intelligent dog I have ever owned with a large vocabulary and very empathic to her owners. She has more drive and protection qualities than most modern bullies, though not as much drive as a real pit. I think these qualities are needed back into the breed so I chose to start from scratch. Nimbus produces larger pups than herself with good temperaments. She is from razor's edge and gottiline. Both studs that we have chosen for her have been from each of those lines, and both are from local kennels and both were featured in Bully Girl magazine. She is being retired and spayed as she has had 3 pregnancies and will stay in our house as the head of the pack of her babies.

About Vesper
Vesper is a blue brindle with really beautiful markings, she was our keeper from her litter. She is UKC and ABR registered. She is Embark Clear and 100% American Bully. Both her parents were Embark and OFA tested so her and her sisters represent the second generation of OFA tested dogs in our program. She already has great looking conformation and a nice old school tight skinned defined classic look with a more terrier look People often say that brindles have great structure and this girl has tight cat feet like her mom. This girl is very athletic and has drive but, she is well behaved in public and at shows on a leash. She is 18 inches and about 65 pounds she definitely has a more classic terrier look for those who like more athletic clean dogs with tight skin with an old school look more like the APBT or Amstaff in their ancestry. She is a tri carrier and carries chocolate and is embark clear. She has passed all her OFA testing of with Hips fair and normal for cardiac, elbows, shoulders and patellas. We just bred her to a UKC GrCh stud.

About Artemus
Artemus is from our Nimbus x Jack litter, she is black seal and carrys chocolate, and dilute. She was reserved to be sold but buyers never completed payment so we have kept her in our program. Artemus is classic / standard size and about 17 inches tall atw with a nice compact frame and short back. She is super sweet and friendly and does well in training and obedience work and loves puppies and other dogs. She loves to go on walks or drives in the car. She almost has a pocket look but she is not and she is the bulliest dog in our program. Although she is compact, she is faster than she looks and loves to run and has athletic ability. I might show her. She passed all OFA tests of hips fair and normal for cardiac, elbows, shoulders and patellas. She is a full sister to Zephyrus and Vesper and both her parents also passed OFA testing prior so they are second generation tested. She is embark DNA tested with one copy of crd4.

Katherine and Kayla were great to work with! They were so responsive and provided regular updates about the pups. Anytime we had a question, they were quick to answer. You can tell that they take great care of their dogs and are wonderful ambassadors for the breed! We are so thankful that we were able to meet them locally and hope to stay in touch. We are so happy with our boy Frankie, he is a sweet, healthy, and happy puppy!
