    Your Pet's Immune System Is the Key to Its Health

    In today’s world, viruses and diseases are rampant, and it can be challenging to protect your pet. Let’s face it. Your dog and cat lives in a world filled with contamination. They spend 90% of their waking hours on the floor, mopping up toxins, chemicals, and pollutants. The household cleaning products, fertilizer on the lawn, and preservatives in their foods can be harmful.

    Bacteria, airborne contaminants, and viruses transmitted by humans can challenge their health. Most pets do not eat an optimal diet, and likely do not get as much exercise as they require.

    Cancer Rates are skyrocketing

    More dogs and cats are being diagnosed with cancer than ever before.

    According to the Veterinary Cancer Society, almost 50% of all dogs and 32% of all cats over the age of 10 will develop cancer. Younger pets are also increasingly at risk.

    “Cancer is affecting our pets at alarming rates, and it is devastating for both the families of these pets as well as the pets themselves. I am seeing this in my practice on a regular basis.”

    - Dr. Jennifer Edwards, Veterinarian at Ponemah Veterinary Hospital in Amherst, New Hampshire.

    “One of the things that can be helpful is supporting your pet’s immune system with antioxidants to help its body to use its own natural defenses against disease. Certain mushrooms and turmeric may be beneficial in helping your pet to boost its immune system to fight diseases,” explains Edwards. According to Dr. Edwards, another way to protect your pets is with all-natural health supplements.

    Pet Owners CAN Make A Difference

    “It is the responsibility of the pet owner to do everything possible to minimize the risk of cancer in their pets. This includes a sensible lifestyle with sufficient exercise, weight management, drinking clean water, healthy food intake, and avoiding toxins.”

    Dr. Shawn Messonnier, Veterinarian and Founder of Paws & Claws Animal Hospital in Plano, Texas.

    “Giving your pets a high-quality antioxidant supplement is highly recommended to further reduce the risk of cancer.”

    Mushrooms = Anticancer Activity

    “As a pet lover, I think it makes sense that the compounds in mushrooms be included in your pet’s diet or included by nutritional supplements. Certain mushrooms contain agents with anticancer activity and mmunomodulatory properties that may help fight cancer and certain other diseases.”

    - Dr. Frank Markland, Professor of biochemistry and molecular medicine at the University of Southern California Keck School of Medicine.

    CID’s with my dogs.

    I have Pebbles, my 6 year old Pit Bull, on CID as a preventative against cancer, which Pit Bull’s are very susceptible to. Annie, my 14 year old Catahoula/Aussie mix has a Spindle Cell tumor on her left front leg, and I’m giving her CID to help with McDowell’s Herbs Spindle Cell Cancer Support. They’ve only been on it for a few weeks, so it’ll be a while before I see any improvement from CID.

    No more PU....lol

    My 2 yorkies (8 and 1 1/2 yrs) have been on it for approximately 2 months. The taste does not seem to bother them...they eat as usual. 👏

    The most pleasant thing we've noticed is that they are not gassy anymore at all. Those "silent but deadlies" are gone. 🤣

    Thank you. 👍

    My doggie loves it

    I found critical immune defense when I found out my dog had lymphoma. I opted out of chemo and instead added this product with prednisone. She is 2 months in and shows no signs of being sick. I sprinkle this on her food twice daily and she devours it.
