We originally got Cowboy to be Tim's companion. At the time, we already lived with two Mastiffs, a girl that had gone blind from several inheritable eye diseases and a boy who had taken on the role of her seeing-eye companion. The two were inseparable. So we got Cowboy to be Tim's fun loving companion, and he fit the bill perfectly. Cowboy loves to act goofy, is always ready to play, and would rather be with Tim than anywhere else.

We knew that Cowboy came from great breeding, but we didn't realize just how well he would turn out. As he grew, we were asked often if we would show him. We knew nothing about showing dogs, it was never in our plans, and we didn't really consider it at first. It wasn't until he was two-and-half years-old that we decided to give it a try. We entered him in the Seattle Dog Show in the spring of 2011. Cowboy met his handler the morning of the show and ended up winning Best of Winners his first weekend out. He was a Champion before we could blink and a Grand Champion before the year was out.

Cowboy is handsome and he's healthy, but most importantly, he has a rock-steady temperament. He goes everywhere with Tim and nothing fazes him. He loves meeting new people. He welcomes those that run up to pet and hug him. When others stand back apprehensively, he gently walks over to them, lowers his head, and leans into them. Cowboy truly believes that everyone should be his friend.

What is a Champion of Health?


Beginning with the 2006 MCOA National Specialty, the Mastiff Club of America, in conjunction with the Orthopedic Foundation for Animals started recognizing Mastiffs which have received significant accomplishments in the ring, in the field, as working dogs, or as producers, AND that have the full complement of appropriate health testing (CHIC Certificate recipients) by issuing them a "Champion of Health Award"

These special Mastiffs have been recognized during the banquet award program at our nationals by receiving the "Champion of Health Award" along with an engraved silver medallion and a $100 donation in the dog's honor to the AKC CHF Mastiff Donor Advised Fund.
If your dog has a CHIC number and has recently celebrated a significant accomplishment at the national level, in the ring, in the field, as a working dog, or as a producer, he or she can be nominated for this exciting award.
Nominations will be made to the MCOA and forwarded to the OFA for their review. The OFA will make the final decision as to who will be awarded the annual "Champion of Health Award"! To submit your dog's name for consideration:

1. You must be a member of the Mastiff Club of America in good standing
2. Your Mastiff must have a CHIC number
3. You must have record of your Mastiff's accomplishments

When submitting a nomination please include the following:
1. Your name and contact information

2. Your Mastiff's full name and call name
3. AKC registration number and date of birth
4. CHIC number
5. Brief description of the accomplishment qualifying this Mastiff for nomination

Submit nominations to:
