Dr. Bill’s Pet Nutrition

The Best Supplements for Your Pet

Dr. Bill has been developing products for the veterinary profession since 1982 – his years of experience ensure that safety, efficacy, and palatability are built into every product. Careful attention to the dog and cat’s specific nutritional needs during different life stages, periods of stress, levels of activity, and certain medical conditions have determined which products are needed most and will produce the best results.

Canine Immune Support

The innate immune system is your pet’s first line of defense against all infectious organisms. Unfortunately, there are many factors that can compromise your pet’s immune system, leaving your dog vulnerable to illness and disease. Dr. Bill’s Immune Support can provide added protection by enhancing the ability of your pet’s innate immune system to detect, track down, and kill invading organisms.

This potent blend of immune enhancers bolsters your dog’s natural immune response, increasing their ability to defend against disease and aid in cellular protection. Immune Support contains a patented and proprietary long chain Beta 1,3 1,6 D-Glucan that scientific research has shown can have a positive impact on the innate immune system, raising it to a level of peak effectiveness.

Proactive Nutritional Support for: Optimum Immune Health Rapid Immune Response Cellular Protection Disease Prevention

Made with High-Quality, Biologically-Appropriate, Natural Ingredients Including:

Colostrum

Colostrum is the pre-milk fluid produced from an animal’s mammary glands during the first few days after giving birth. This rich source of antibodies, growth factors, and other nutrients provides temporary passive immunity against various infectious organisms that affect the gastrointestinal tract of newborns.

Echinacea

Echinacea is an herb native to North America that is widely used as a traditional herbal remedy to fight infections. Echinacea seems to activate chemicals in the body that decrease inflammation and aids in the production of additional T-cells.

Turkey Tail Mushrooms

Turkey Tail mushrooms contain natural compounds (PSK and PSP) that enhance your pet’s defenses by boosting immune cell activity and supporting gut health. Rich in antioxidants, these mushrooms help reduce oxidative stress while promoting cellular wellness. Studies show these mushrooms may help maintain your pet’s resilience during times of stress or seasonal challenges. Give your furry companion the natural protection they deserve!

Turmeric

Turmeric’s active compound curcumin regulates immune responses, ensuring your pet’s body reacts appropriately to threats. This powerful antioxidant protects immune cells while supporting digestive balance—essential for overall immunity. Turmeric promotes healthy immune cell function and longevity, giving your furry friend comprehensive support for their daily adventures!

Supplements for All Stages of Life

Puppies

There is a serious “Immunity Gap” that occurs between the ages of 8-12 weeks. During this period, puppies are most vulnerable to infectious organisms and disease as their maternal antibodies are decreasing rapidly and their acquired immunity has not kicked in yet. Canine Immune Support contains the needed immune-enhancing nutrients needed to help the innate immune system act as an ultimate protector.

Other Recommended Products include Canine Ultimate Fitness & Health, Canine Health Defense, Canine Joint Protect, Canine Digestive Support, and Canine Behavior Support.

Adult Dogs

Your dog can be exposed to just about anything on its daily walks, runs, or trips to the dog park. When they get sick, how much do those visits to the veterinary clinic cost? Avoiding those large expenses can be as simple as using Canine Immune Support to enhance your dog’s innate immune system. Protecting your dog against disease-causing organisms out there is an easy investment for their overall health.

Other Recommended Products include Canine Ultimate Fitness & Health, Canine Health Defense, Canine Joint Protect, Canine Optimum Skin & Coat, Canine Digestive Support, and Canine Behavior Support.

Senior Dogs

Canine Immune Support is a critical element for all canine seniors as their acquired immunity begins to gradually fall off, making them more susceptible to infectious diseases. Enhancing the innate immune system can help seniors compensate for the decrease in their overall immune system.

Other Recommended Products include Canine Ultimate Fitness & Health, Canine Health Defense, Canine Joint Protect, Canine Complete Joint Care, Canine Cognitive Support, Canine Digestive Support, and Canine Optimum Skin & Coat.
