CANCER IS NOW THE #1 KILLER OF DOGS AND CATS. Sadly, according to the Veterinary Cancer Society, almost HALF of all dogs (and 32 percent of cats) over the age of 10 will be diagnosed with cancer. These are shocking statistics! Younger pets are also developing cancer at higher rates than we’ve ever seen before. A strong immune system can protect against disease and ensure your pet stay healthy for years to come.

“The difference in his health and energy is amazing!”

My beautiful dog Hooch was diagnosed with cancer a few months ago. I’ve been using Critical Immune defense combined with your probiotic for about a month and the difference is amazing! Hooch seems to be in better spirits and he is eating again. He saw me taking one of my other dogs for a walk and came to the fence and put his nose on the leash like “I want to go too.” I know he is feeling better, and I feel that the Critical Immune Defense and the Probiotic are working!

My dog had been on steroids for a back injury and developed a bacterial skin infection as a result. I was concerned he might have immune system problems. This product is made in the USA and is all natural, and I can use it with his allergy meds & antibiotics. He loves the taste, even licks the bowl to get it all. I think this product has helped him very much to combat this bacterial infection. He is 11 yrs old and I want him to live a long, healthy life.

We highly recommend Critical Immune Defense! Our 8 year old Golden Retriever gobbles it up and we feel so good knowing it's an all-natural product (and made in the USA). Thank you for making it so easy to boost our dog's immune system!

My dog loves Critical Immune Defense. No problem with taste and the ingredients are great. He’s an old timer -- 15 ½ years old -- and 70 pounds and he’s doing well despite diabetes and a neurological impairment. He still goes for his walks, albeit, very slowly.
