Maximum Health for Adult Dogs

Dr. Bill’s Supplement Recommendations

Dr. Bill examining dog
“Dogs and their nutrition needs vary widely. Of the 250 purebred canine breeds, some are highly active, others grow up to become couch-potatoes, while a select few may go on to become full fledged athletes. All these breeds range in weight from 3 to 250 pounds! Every dog requires different levels of energy, protein, and specialty nutrients that are rarely found in commercially prepared pet foods.

We all want our dogs to live the longest, healthiest, and happiest life possible. So, let me tell you about some of the products that I give to my dogs when they become adults to ensure they always receive Optimum Nutrition.”

—Dr. Bill Barnett

Canine Ultimate Fitness & Health

The most important is my foundational nutrient supplement, Canine Ultimate Fitness & Health. With 87 essential and specialty nutrients in every scoop, this product can improve overall wellness, help maintain a healthy weight, and provide proactive nutrition benefits that will benefit your dog well into senior life. Canine Ultimate Fitness & Health is an easy way to ensure your dog is receiving everything they need for a healthy diet. Like most of my formulas it is a delicious powder that can be mixed with wet food, sprinkled on top of dry food, or even mixed with warm water to make a tasty broth. During over fifty years of animal nutrition research I found that powders are the easiest to use and also the most successful way to introducing new foods to dogs and cats.
Our dogs can encounter many pathogens that can make them sick, especially if they spend time outdoors or like to socialize with other dogs. So, two complementary products I like to give to my adult dogs along with Ultimate Fitness & Health are Canine Immune Support and Canine Health Defense. These two products contain essential nutrients that can help keep your dog healthy, especially dogs who like to sniff, lick and chew everything they find outside or are always socializing with other dogs at the dog park.

Canine Immune Support

Immune Support helps your dog’s innate immune system fight off all the disease-causing organisms their sniffing, licking and chewing continually exposes them to. A strong, healthy immune system is the best protection against illness, and Canine Immune Support includes an exclusive long chain Beta Glucan that works to enhance your dog’s innate immune system.

Canine Health Defense

Health Defense provides essential nutrients to accelerate healing. Starting around 1 year of age, antioxidant production in the dog reaches its peak and then begins to drop off as they reach their senior years. Unfortunately, throughout a dog’s life there are many times where the safety threshold of protective antioxidant levels can be surpassed by an overwhelming number of free radicals. Canine Health Defense is designed to supply millions of additional antioxidants to combat these increases in free radicals that when left unchecked can create enough cellular damage to produce long term debilitating disease.

More Adult Dog Supplements We Recommend

Canine Optimum Skin & Coat

Fleas, mites, bacteria, insufficient nutrition, even seasonal weather conditions can cause significant problems with the skin and coat of your dog. For medium to long coated dogs Canine Optimum Skin & Coat may be substituted for Ultimate Fitness & Health. Optimum Skin & Coat has clinically proven its effectiveness for over 35 years for veterinarians and premier breeders.

Canine Digestive Support

Like puppies, adult dogs also like to eat all kinds of things like poisonous plants, snails, rocks, sticks, toys, even garbage. This often results in stomach or intestinal problems such as vomiting and diarrhea. One product you might want to keep on hand is my Canine Digestive Support. It can sooth those stomach problems and the billions of helpful pre and probiotic cultures can repopulate the lost micro-flora stabilizing the intestinal tract once again for optimum gut health.

Canine Joint Protect

I recommend that all large and giant breed dogs, and highly active dogs, take Canine Joint Protect. Many breeds are especially susceptible to joint problems and Canine Joint Protect provides additional lubrication and joint repairing support nutrients needed to help protect against future debilitating joint problems. (If your dog is already experiencing joint problems then they need Canine Complete Joint Care.)

Canine Behavior Support

Dogs are so enjoyable when they are well behaved, but unfortunately that is not always the case. Just like people, many things can cause a dog to feel stress and anxiety, and this can lead to undesirable behaviors: Excessive barking or begging at dinnertime. Aggressively confronting other dogs when you are out walking. Problems when you leave them alone or take them in the car. Chewing on furniture. Soiling the carpet. Lack of attention when you are trying to train them. Canine Behavior Support is a natural calming formula that can help relieve the stress and anxiety that cause these unwanted behaviors. Best of all, Canine Behavior Support calms your dog without making them dopey or sleepy.

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.”

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!”

-Kelsey J., Pet Parent & Satisfied Dr. Bill’s Customer

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!)”

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!”
