Breed pug
Arthritic dog on the way to recovery
My 6-year-old pug was born with a bad knee joint that began causing her arthritic pain this year. I changed her diet (now higher in protein, but she's always been fed the best foods), added both glucosamine and omega 3 supplements, and agreed to both Adaquan injections and a short-term Rimadyl prescription. While she was definitely improving, her pain between the Adaquan injections was noticeably greater and the Rimadyl eventually caused her to lose her appetite. I took her off the Rimadyl, but no prescription pain killer seemed to help her much. A month ago, I came across this supplement, bought it, and began giving it to her every day along with getting her cold laser light therapy. For the first 2.5 weeks, she had loose stool, which I didn't worry about since I knew that this might be a possible sign that the supplement had started to work. Three weeks in, my dog is getting around much better, clearly with minimal pain, and beginning to feel like her normal self. Her limp is gone, she has a little morning stiffness, but the stiffness continues to diminish with each week that she takes this supplement. What a relief! I have no doubt that this supplement has enabled her body to more rapidly and efficiently heal the problem joint. Based on the progress I've seen in 3 weeks, I'm hopeful that all signs of stiffness will soon be gone.

Breed Border Collie/Lab Mix
Slow, but very effective
My Border Collie/Lab Mix (78 pounds) had large(size of a quarter!), itchy red bumps on his back that the vet had treated with two rounds of oral antibiotics and steroids, only to return each time. She suggested expensive testing. After reading many reviews on 1-800-PetMeds, I decided to try the combination of: Proanthozone Antioxidant 50mg, Yucca Intensive Anti-Inflammatory, Super Pure Omega 3 Soft Gel Caps and 1-800-PetMeds Be Soothed 12oz Spray. He absolutely did not like when I sprayed the Be Soothed on him, after about two weeks, I came to the conclusion that this was very irritating to him and making the spots worse, so I stopped using it. When I tapered the dose of the Proanthozone, the little bit of improvement that I had seen, ceased, so I went back to the higher dose of 3 every day and that is when everything started to show great improvement! It took about 4 weeks, but they are finally starting to dry out and heal, so I am reordering the Proanthozone, Yucca Intensive and Super Pure Omega. I do have to mix all of this in with a little bit of wet food or chicken broth and dry food. Unlike others, my dog does not think any of these are treats!

A product that is dear to my heart.
PROANTHOZONE: This is a product that is especially dear to my heart as it was one of the first effective products I used back in the mid 1990s that convinced me of the value of complimentary and alternative medicine supplements and products. This powerful antioxidant which is 20 to 50 times as powerful as vitamins E and C in its antioxidant activity has a wide variety of uses in everyday veterinary medicine for both dogs and cats. The most common place I have used this versatile product is in stiff or arthritic dogs and cats. Its wonderful antioxidant and anti inflammatory effects, as well as its effect on enhancing collagen production in the body (which is the main glue of our connective tissue and joints), has been a tremendous benefit in both treating and preventing stiffness and arthritis in my practice. When combined with an excellent glucosamine product like super joint enhancer from 1800petmeds, in addition to omega 3 fatty acids added to meals, I have seen amazing clinical effects on stiff or arthritic pets, often minimizing how much conventional prescription nonsteroidal anti inflammatory medication I need to use, which thus cuts down on risks and side effects to the dog or cat. Because of its antioxidant and anti inflammatory effect, I have found proanthozone also to be useful in a plethora of other conditions, including skin allergies, blood and blood vessel disorders, and other inflammatory diseases in the body including liver disease and pancreatitis just to name a few conditions. I highly recommend and endorse this product for any pet, especially the aging dog or cat, where damaging chemicals called free radicals are produced in their bodies leading to degenerative disease of any organ system, which proanthozone can help prevent, along with a good natural diet. I find very little downside to this product, except for perhaps the expense in a larger breed of dog, but to me the preventative benefits are well worth it. My overall rating of this product is a 5. Its effectiveness is a 4.5, and its ease of use is a 4. As with any product that comes in a capsule form, I have occasionally found it difficult to administer to cats, but many will often take it mixed in with their food.
