Maximum Health for Active & Performance Dogs

Dr. Bill’s Supplement Recommendations

Dr. Bill examining dog

“I do not know a single human athlete who doesn’t have a  specific regimen that helps  them to maximize their ability to perform at their best. This usually includes specific diets, supplements, and exercise in order to maximize their fitness & strength and obtain that extra winning edge. Our performance and working dog are  true athletes that deserve no less.”

“Over the years, performance dogs such as show, obedience, agility, hunting, police, military, racing, and the ultimate endurance athlete the Iditarod sled dog have all benefitted from my Ultimate Fitness & Health Supplement.  Each of these performance dogs experience  various levels of stress,  and  frequently can be exposed to pathogens when coming into contact with other dogs and/or the environment. Therefore, I highly recommend my tried-and-true combination of  Ultimate Fitness & Health supplements – Canine Ultimate Fitness & Health, Canine Immune Support and Canine Health Defense.”

—Dr. Bill Barnett

Canine Ultimate Fitness & Health

Ultimate Fitness & Health is where you should start as it provides a powerful foundation to ensure your active dog is receiving everything it needs. It supplies 83 essential and specialty ingredients for the variable daily needs of the canine athlete. Dosage levels for the Ultimate Fitness product can be altered depending on the level of energy output. For low level performance the standard daily dose should be sufficient. For higher levels of energy and stress, doubling the daily dose may be used. Depending on the length and severity of any high-level performance, three to four times the daily dose may be required. I know Iditarod mushers who put 8 ounces of Ultimate Fitness & Health into each dog’s nightly supply of water during these multi-day endurance races.

Canine Immune Support

Canine Immune Support provides a proprietary blend of 41 innate immune system enhancers to protect your active dog from infectious agents that can put them on the sideline. Immune Support is especially important for dogs who are constantly exposed to  new environments, new dogs and a wider range of disease-causing organisms.

Canine Health Defense

Throughout life, especially for dogs who engage in intense activity levels, there are periods where the safety threshold of protective antioxidant levels can be surpassed by an overwhelming number of free radicals The 42 active ingredients in Canine Health Defense are a useful addition to Ultimate Fitness & Health as they can supply millions of additional antioxidants to combat the increase in free radicals that when left unchecked can create enough cellular damage to produce long term debilitating illness, injury, or disease.

More Performance Dog Supplements We Recommend

Canine Optimum Skin & Coat

Whether its hair loss from whelping a litter or recovery from seasonal shedding, Optimum Skin & Coat will help you get back to that winning appearance with a luxurious, full coat that says, “I’m a winner”. Show dogs need to not only be in peak health, but also look spectacular to be successful. For medium to long coated show breeds Canine Optimum Skin & Coat may be substituted for Ultimate Fitness & Health. Optimum Skin & Coat may also be used with Immune Support and Health Defense to protect your dog from just about everything possible that show, obedience, and agility dogs are exposed to when they come in contact with hundreds of dogs competing from all over the country.

Canine Joint Protect

It is common for performance dogs of all breeds to experience joint injury and stress as they are pushed to the limit, sometimes beyond what their joints can physically take. All performance breeds can benefit greatly from Canine Joint Protect, which can provide the additional lubrication and joint nutrients needed to help rebuild and support the heavily stressed joint structures of our canine athletes.

Canine Complete Joint Care

Repeated joint injuries, no matter how minor, eventually lead to osteoarthritis – a painful and debilitating disease that can sideline even the best athletic dogs. Canine Complete Joint Care provides joint-healing nutrients as well as support for increased muscle, ligament, and tendon strength needed to support recovering joints. Canine Complete Joint Care assists in decreasing inflammation so joint and ligament healing can begin. By providing the specialty nutrients necessary for healing you are doing what is necessary to lessen the amount of painful arthritis any performance dog is going to experience as the years of athletic activity begin to mount up. No other ingredient I have found compares to the power of the proprietary Aliva Joint Health Complex, exclusive to this Dr. Bill’s nutritional supplement.

Truly a miracle product!

“I’m actually astonished at how effective this product has been! It has made an ENORMOUS difference for our dog, Indie. We started administering the supplement to Indie, and then left on a trip to London for a week. Our dog sitters fed Indie the supplement each day, according to the instructions on the label. When we returned from our trip, Indie’s coat was glistening! It’s so much more lustrous and smooth, with less shedding. What’s more — Indie LOVES the taste of this stuff! I can’t believe the improvement we’ve seen in only a week! Truly a miracle product! So glad we found this hidden gem, and I’m excited to see how Indie’s coat looks in a month from now! Thank you, Dr. BIll! We’ll be using your products for life! (P.S. Another bonus is that the serving scoop is actually quite small, so this product will last you a long time!)”

We've noticed HUGE improvements in her joints, health, and happiness

“We have a 9 year old chocolate lab and she had a major hip injury and surgery a few years back and her joints have never been the same. We have started giving her Dr. Bill’s Canine Complete Joint Care and have noticed HUGE improvements in her joints, health and happiness. She hasn’t been able to jump on our bed to snuggle for years and since taking this we have woken up with her snuggling up right next to us in the mornings!”

I was shocked at how thick and smooth her coat had become!

“My dog, Lola, has suffered from itchy, dry skin her whole life. Her coat always felt a little dry and wiry. I started her on Dr. Bill’s Skin & Coat formula with few expectations, hoping it may at least help her itch just a little less. Then I went out of town for a week and when I returned, I was shocked at how thick and smooth her coat had become. I didn’t think it was possible. Not to mention, the powder smells so good, I feel like I am serving her a gourmet meal each time I sprinkle it over her dry food. Lola is a happy girl!”

Her health has taken a 180 degree turn

“I’ve been giving Lily Dr. Bill’s Digestive Support for about 4 months now and it has helped her SOOOOO much! We had been battling her digestive issues off and on for a few years now (vomiting, diarrhea, and skin reactions to food) resulting in some pretty significant vet bills. What we learned was that she was not processing her food properly. Through adjusting her diet and supplementing with Dr. Bill’s probiotics and enzymes, her health has taken a 180 degree turn. She’s feeling so good! She’s so much healthier and happier, and honestly even nicer. I think having digestive issues was just making her cranky a lot of the time. And she loves the taste of Dr. Bill’s powder, so that makes it super easy to give to her regularly. We love Dr. Bill’s!”

-Andrea M., Pet Parent & Satisfied Dr. Bill’s Customer

Made all the difference!

“I was dog sitting my son’s mixed-breed rescue while he was out of town. It was pretty evident when he got him that he had been abused, but he was doing much better over time. Pare hadn’t been to my condo before and he was so scared it hurt my heart. Cowering and afraid if I left the room. My sister-in-law uses Behavior Support on her rescue with great success, so she gave me some to try. Made all the difference! He didn’t act drugged; was just way less anxious and no more cowering.”
