Best item ever purchased by snowowl01/26/2014
6 months ago my dog Nugget was diagnosed with Sarcoma in his hock. He underwent surgery to remove the growth, however I was told it would more than likely come back. Two days prior to surgery a friend told me about CAS Options. I ordered two bottles and on day three which was a day after his surgery I started him on CAS Options. To this date the growth has not come back. He loves the taste and think there his treats. Believe me if it had anything to due with medication he runs. I'm a true believer in this product. Thank you for a great product.

We've used this product with 2 different German Shepherds. The first dog had a tumor that was removed and the biopsy indicated it was a very aggressive form of cancer. There was literally no option for cutting deeper to get clean margins without amputating the dog's front leg and part of the shoulder. Perhaps equally as bad, the oncology protocol (months of radiation treatments) was something that bordered on cruelty given the dog's age and physical condition.

Magical Mushroom Mash? by Mary D. from New Jersey01/30/2015
This rating is a bit premature, as my dog has not yet finished the entire first bottle of this product; but, so far so good. Angelica was diagnosed with hemangiosarcoma in August 2014 at the age of 12. After removing the tumor from her spleen, the liver biopsy tested positive that the cancer had spread there, even though there was no visible evidence of the disease. We opted for chemotherapy treatments--a total of five rounds given three weeks apart. No supplements were given during the course of her treatment. She completed the last round at the end of November. A follow-up visit with her oncologist in mid-January showed that my dog is now in remission. I decided to start her on this supplement with the hope it will keep the disease at bay. Her next check-up is in March. I'll write another update of how she's doing after her visit. Until then, I'm praying that we'll receive more happy news.
Very happy with this product by Sark from Clovis05/10/2014
I have a 15 yr. old Cairn Terrier, an herbalist told me about this product a few years ago & have been giving it to her ever since. She acts like a dog half her age.
Unknown if the product worked.. by AMY from Indialantic, FL07/19/2012
My beloved Amy passed away on the 15th of July.. We are heart broken. She was extremely special and cannot ever be replaced. We pray for her to rest in peace painfree...

Excellent for Dogs with Cancer by Guinness from Torrington, CT08/20/2012
This product, along with a raw diet, herbal tea blends and some herb tinctures are keeping my 13 year old dog alive and happy since being diagnosed with Hemangiosarcoma in March of 2012.
He shows no symptoms of the cancer progressing since having his spleen with tumor removed. He is active and looking great.
Great product by Ktyogini10/08/2013
I've been giving this product to my dog for over 6 years based on the recommendation of his oncologist. He's a cancer survivor who is about to turn 15 and I credit this product as one of the reasons why. And Entirely Pets is the only place I've found it online...at a great price. Thanks for carrying it and never stop.
Seems to Help with Lymphoma Remission by Daisy the Beagle from Orlando, FL10/08/2013
I have been giving this to my beagle for about a year now. We started not long after her chemo treatments began. An integrative medicine practioner recommended shiitake mushrooms & this is the supplement we chose due to the combination of mushrooms it contains. I easily crumble the tablets & add to her dry food. I can't say for sure if this works & I can't say it doesn't, but with such success with her treatments & remission, I never let this supplement run out. Highly recommended from my perspective.
Came Highly Recommended by Grey Mom10/27/2011
My vet recommended my greyhoound switch to this antioxident after he had a malignant tumor removed. She has never steered me wrong.
Good for dogs with a Cancer diagnosis by Pebbs from Arizona03/17/2013
Have used this to support our dog with Mast Cell Tumors. Recommend it.
Helping to beat cancer by dgm from Minnesota11/16/2011
Our 4 year old mixed breed has bone cancer. After a traumatic and unsuccessful traditional treatment route with another dog years back we decided to go with a supportive holistic approach this time. CAS Options is only one of the natural supplements we use, but I believe it is contributing to success so far. Three months after diagnosis there is no spread of the cancer and he's happy and active. I've started giving it to all of our senior dogs - maybe it will keep them all healthy.
No results yet! by LynnePlus311/06/2011
I haven't noticed any difference/improvement in ANY of my dogs since starting this product- in fact it made one dog sick with diarrhea !!! I will keep using it for a while to see if there's any improvement AND because it cost so much!!!
And none of them like the taste!
Prescribed by my holistic vet by Clare06/28/2014
Easy to feed and our dog likes the taste. Vet says one of the best antioxidant out there
The Product May Be Extending Our Dog's Life by John L from Huntsville, Alabama07/25/2012
Our 13 year old Shih Tzu Abby stopped eating so we had lab work done which showed her liver enzymes to to over 10 times normal levels. We then had an ultrasound done and the vet saw a mass around her liver. The vet thinks it is cancer and felt she probably only had a few weeks to live. I researched alternative drugs and found CAS Options, Denamarin, and Prozyme were all highly recommended to fight the cancer and possibly regenerate the liver function . After 7+ weeks on these 3 drugs, I am happy to report Abby is still with us and she doesn't exhibit any symptoms of liver failure so far. She still will not eat on her own and must be hand fed (which takes up to 2 hours a day), but she is eating better and I have faith that soon she will start eating on her own again. I can't say these are miracle cures, but so far I am impressed with where we are in extending her life and maybe some kind of recovery.
Product is great Entirely Pets is horrible!!!! by ampc4211/28/2012
CAS Options is amazing, but when you can't depend on Entirely Pets to process your order-even after they have charged your credit card it won't do you or your dog any good! 13 days after placing my order they confirm that my order has not shipped, even after telling me that it has. I won't be using Entirely Pets again!!!!!
