From the brand
For over 30 years, we have been manufacturing products to ensure the superior quality of life our pets deserve.
After our rescue dog, Winston, was diagnosed with arthritis & hip dysplasia, we began researching alternative medicine while working with Dr. Pedro Rivera. After several months, we developed a natural joint formula that gave Winston a second chance at life.
And thus, VETCLASSICS was born.

Truly a Life Saver!
I donât ordinarily write reviews, but I had to write one for CAS Options. This supplement literally saved my dogâs 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 deathâs 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 canât 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.

New life for your 4 legged best friends
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.

A Great Option for Immune Support!
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!

Immune supplement
I purchased this supplement because itâs a mushroom base. One of my dogs has a small tumor, and because of her age, my hope is that it will dissolve it.

Keeps my 19-1/2 yr old dog going!
Kaylee (30 lb. mixed breed) had a cancerous tumor removed from her jaw when she was 15 and the vets predicted the cancer would return. They put her life-expectancy at under 2 years. Not wanting to put her through chemo in her last year(s), I took the advice of a holistic vet and started giving her CAS Options. Four years later, she’s still going strong. Her eyesight isn’t great, and her hind legs are beginning to weaken, but the cancer hasn’t returned, her appetite is great, cognitively she’s “all there.” She still greets me at the door, still begs for treats, and she has kept me sane through these last two pandemic years.

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.
