    It’s so good for your dog no matter what the age
    I think this stuff is great my 20 year-old. Shih Tzu is now running and playing with my three year-old dog instead of just laying and barking at him. He gets up and plays with him and tries to run with him and he’s in great health at 20 years old.

    Great product.
    This is a great product. I give this to my dogs daily to boost their immune system. I add it to their food, have had no ill effects with them on this product.

    I AM BACK TO BUY MORE!
    I got this, despite the price, just to see. My son has a seven-year-old Aussie who was no longer wanting to chase the ball, who stood back and just didn’t seem to care about playing anymore with our two younger dogs. It was so sad to see! He is still so young. I remembered reading about Critical Immune Defense and seeing good reviews. So, despite the cost, I decided to order some. I gave my grand-dog, Gus, his two scoops on his food per meal for three days. (I did mention to my son that I was doing so. It is his dog, after all.) So we sailed along for three days, and all of a sudden, my grand-dog, Gus, began bursting forward to chase the ball and play. He was like a puppy again, all excited and racing around. It made my heart swell, because I was thinking, “That Stuff is actually Working!” My son said nothing. So, I thought, okay, fine. I can do without spending all that money on snake poison, even though I believed I was seeing a huge change in my grand-dog, Gus. My thought was, “I saw a placebo effect. I convinced myself, so I believed in the hype.” My son didn’t mention seeing a difference. So, hello, the stuff is expensive. I decided not to buy anymore. I’m not an idiot.So a few days later, my son calls. “Mom, are you still giving Gus his supplement?” I thought I had messed up, because I wasn’t giving him anything. I was, like, WHAT supplement? My son was, like, that stuff that started making him play like a puppy again! My son was very upset that I had stopped giving his dog the CID. He would have been eagerly willing to continue the supplement at his own cost and trouble! The difference in the dog was huge. I became upset, only because, what? You never said a word about how it changed Gus. Why would I continue giving it to him? The stuff is expensive! I hope the company can shave away at their overhead to reduce the cost of product. Bottom line, this stuff DOES work! It isn’t about buying it and only thinking it works. It truly does, and our Gus is suddenly running and playing like a much younger dog. It has given him a new lease on life. I have decided to also give it to my two younger dogs, hopefully as a preventative supplement. And, hello, I’m researching to find a human-grade supplement with mostly the same ingredients. I could stand a boost in the arm to make me feel better, too!

    IF YOU VALUE YOUR DOGS LIFE…DO NOT BUY!!
    I never write reviews but Milky my Bichon Poodle almost died. After I sprinkled this product on his food, he refused to eat it. I coaxed him into eating, not realizing the danger.The next morning, he usually jumps down from my bed, but this time he was whining and needed help. When I placed him on the floor, he couldn’t walk—he couldn’t even stand on his own. I lifted him up, and he began limping across the floor. From what I could tell, only one leg was really working.Panicked, I began to pray over him olive oil mix with 2 drops of oil of oregano with black seed and gave him plenty of water to flush the product out of his system. I’m currently unemployed and was praying we wouldn’t have to go to the vet. The whole reason I bought this product was to avoid a vet visit as a preventative measure. He’s 15 yrs, but other than some possible dental issues, he’s generally fine.That entire day, he struggled to walk, limping and needing help up and down the stairs. It was a mess. I even called my pastor, who prayed for him over the phone.Then, late in the night, I heard him jump off the bed. Thank God! The next day, he was doing much better and could walk again—still a little unsteady, but by the evening, it was like nothing had happened. He was back to running around as usual.Stay clear of this stuff! I went back and read the one-star reviews, and I saw that two dogs had died after using this product. If I had seen those reviews earlier, I never would have bought it. Of course there’s no refund.If your dog refuses to eat something, trust them. Do not push it.I’m so blessed he made it through.

    Dexter, my CAT, loves the taste!
    I just received this and for the heck of it I put some down on a saucer for Dexter (cat) to investigate. He ate it right up! I just want to let it be known that there are cats that like this and don’t be afraid to try it. I’m hoping that this will continue and that the results he has is as positive as some of those that I have read about. Best of luck to everyone trying this.

    Helped Our 15yr Old Maltese
    We noticed that our 15year old Maltese had a huge swollen lump the size of a tangerine protruding from her belly. She was not eating or drinking, not moving, acting very lethargic, she was suffering. It wasn’t looking good, we were anticipating the worst. We started mixing this product with her food. Within 2 weeks the lump has drastically reduced, shrinking every time we check. She’s back to her normal eating and drinking routine and definitely has more energy. Reading the product reviews of others with similar stories to ours gave us the confidence give it a try. So glad we did and that it helped our pup.

    On the Fence
    Honestly not sure if this helped my 15YO Lab or not. I went through three jars in less than three months, as the dosage for him was two scoops twice daily. I’d hoped to see a reduction in his fatty tumors, but like all the other products I tried, it did not help. Prior to this I’d also tried Turkey tail mushroom for some time, with no results. Needless to say, it’s frustrating. One positive is that he had no problem enjoying his food with this mixed into it. Overall, I t’s too pricey to keep up with, when one jar doesn’t even last a month, to not see any results from it. I’d rather spend the money on maintaining a well-balanced diet and continue with other supplements he’s on.
