- CAS Options Extra Strength Immune Support for Dogs, Cats – Pet Health Supplement, Dog Antioxidant Care – Extra-Strength Dog Supplement Formula – 120 Chewable Tablets

I don’t ordinarily write reviews, but I had to write one for CAS Options. 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.

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.

I decided to try on my two senior labradors, both with fatty tumors, after reading reviews that some said, helped. I will say upfront, that I don't give the directed amount due to cost of CAS :(. My labs are 120 lbs and 90 lbs, so even at 4 per day per dog, it goes quickly. It is much cheaper than vet visits, but it all adds up as I also give my dogs several other natural meds which they cannot do without because of the benefit it provides (Only Natural Pet's Get Up and Go, Thyroid Support and Resources Pain Plus). So our monthly supplemental bill is not pretty, but my conscience simply cannot give them RX drugs, even if cheaper, when I know they will have ill side-effects. My 11 yr old female lab seems to benefit greatly from CAS, she acts like a young pup again and her tumors seem to be decreasing in size. My 13 yr old male lab continues to get more tumors, and doesn't seem to have changed much in affect, but I am sure it is helping to support his immune system none-the-less. The only reason for 4 stars....price!

Bought this to help shrink my dogs fatty lumps. 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)

I started giving this to my 10 year old Schnauzer mix. He had slowed down a lot and had many of those fatty like tumors. Within 2 months on this product he is more active and some of those tumors shrunk. I then started my 8 year old Shepherd and she is also more active. This product is a little pricey but worth it. My dogs are acting like puppies which makes me very happy. There is milk thistle in it and I know that helps the liver, a very important organ for people and companions! I thought I was looking at Eddie's end and feel we both have a lot more time together. I found out about the manufacturer from my vet who suggested the Blood and Energy for anemia that my Shepherd needed.

We've used this product for over 6 years for our dogs. It works great and keeps our dogs very healthy!!

Good and bad! I absolutely love some of the ingredients in this, but why ruin it with some questionable additives?!?! I have a 6 yr old St Bernard with cancer and read where this product came highly recommended. I purchased spur of the moment without reading the ingredients list. Some I’m not knowledgeable about but canola oil, vegetable oil (seed oils are highly inflammatory and over processed junk), natural flavoring (could be any of 1000’s of chemicals) tapioca starch (high carb-not great for a dog with cancer)??!! Darn it! I really wanted to like this product and am desperately trying to help my big rescue boy! 🐶

My holistic vet originally recommended this to me for my old dog who had cancer. One of my current dogs has a lot of immune issues - hot spots, itching, smelly ears and greasy skin/coat. I've tried many other supplements, herbs, coconut oil, etc. with no effect. What has helped are specific medicated baths recommended by the vet and this supplement. Even though I had last used this supplement over 5 years ago for my old dog, I kept coming back to the listing. I think my intuition was telling me to try it for my current dog. I do believe it has helped with her itching - not eliminated completely but reduced drastically. We ran out a few weeks ago, so she has regressed (summer weather picking up also doesn't help). I will be reordering. It is well worth the money.
