This supplement literally saved my dog’s life. In 2013, our family was exposed to illegal, industrial grade pesticides. The humans struggled w severe illness for at least two years, and our 11 year old dog (a 13lb terrier) was at death’s door. His lungs were filled w fluid and inflammation, he was exhausted and could hardly walk, he could not hold his urine, and his kidneys were breaking down. Our vet tried every prescription he could think of, but honestly, there was very little progress and euthanasia was brought up by the vet staff. Desperate, I brought my dog to a vet who specialized in vitamin and diet supplementation. She recommended CAS Options as a foundational, daily support. This supplement not only brought my pup back to FULL AND COMPLETE health, but I believe it kept him from developing cancer (which the vets said would almost definitely happen due to the pesticides). My dog was happy and healthy for 6 more years!! My dog passed a few months ago, at age 17. He struggled for about a week while we tried to fight off a c-difficle intestinal bug. Then one night, he had a seizure. I picked him up, held him, and prayed aloud as I felt his heart and breathing stop. It was very quick- maybe 30 seconds? Not a bad way to go at all. I miss him terribly, but I feel blessed to have had him healthy and happy for 17 years! From 2013 until the day he passed away, my dog always got his half tablet of CAS Options. I sincerely believe this supplement kept him as healthy as possible during his senior years. He truly was vibrant, active, and generally healthy all those years! I can’t say enough positive things about this product, honestly. Oh! One hesitation I know that my family has in purchasing this product for their pups is the cost. Yes, this supplement is not inexpensive. However, I truly believe that this supplement spared me thousands of additional dollars in medication and vet bills, as well as the additional heartache and suffering for me and my dog. When thinking about it in those terms, CAS Options was a bargain! Like I said, I very rarely write reviews, and I cant tell you the last time I was so enthusiastic about a product. I wanted to write this so that others have the opportunity to return their dog to health, too. Review: HIGHLY RECOMMEND! - This is the absolute answer to my poodle's fatty tumors. Vet said nothing needed to be done unless they attached deeper. He had at least four maybe more and two of them quiet large especially the one on his chest. I ran across this as I was googling things and decided to give it a try even though the item seemed quiet expensive. I started giving 1/2 of a pill in the morning and the other half in the evening. After 3 to 4 weeks I could tell the tumors were getting smaller. I started him on him Sept 1st 2020 and now October 18, you can barely feel them. He use to choke after drinking water at times but no more. He has also loss weight due to loosing the fatty tumors. For those who said they were stinky and made their pet sick. I do understand as this are made from mushrooms and it they smell stinky or sour, they are bad. My has an expiration date on the lid which say best by 12-2022. So I have a couple of years. I'm not sure how long I need to give the halves to him after the tumors are totally gone. I highly recommend these. ## Features - DOG IMMUNE SUPPORT: Fuel your pet with the support he needs to stay healthy and support his immune system. - PET HEALTH SUPPLEMENT: Give your furry friend the immune support he needs with these health supplements for dogs and cats that include some natural ingredients such as maitake mushrooms, shiitake mushrooms, turkey tail mushrooms and reishi mushrooms. - PET IMMUNE SUPPORT FORMULA: A healthy immune system is essential for dogs and cats.

It is helping with these but, the best thing about this is it has stopped my dog from shedding. I mean 14 years of constant shedding and then just stopped after 3 weeks of taking CAS. This to me is enough reason to keep Willyboy on CAS. I also have noticed my little guy has more energy and generally seems more happy. I am one very happy customer. Thank you, Willyboy's mom Update: Second bottle delivered was of a different consistency. My two little dogs who would beg for these when they saw me holding the bottle, now won't touch them. I called customer service and they told me the ingredients are sourced from different places. She sent me a new bottle with a different lot # at no charge. I was hopfull only to have the same problems. I have to hide them in their food now. Oh, and the shedding is back big time from my Willyboy. Wish I had kept the lot# of the first magical bottle I received so I could request that lot only. (The one that actually works and that the dogs enjoyed and begged for) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/30622476-cas-options-extra-strength-immune-support-for-dogs-cats-pet](https://www.desertcart.co.th/products/30622476-cas-options-extra-strength-immune-support-for-dogs-cats-pet) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-22*
