My frenchy has a rare oral tumor. He was given only a few months to live. I immediately began giving him s supplements geared towards fighting his cancer. In January 2025 10 months into his fight I came across the Mass Dissolver and figured I would give it a try. We are on our third bottle and my dogs tumor has begun to shrink, it’s also softened. He also seems to overall feel better. He is playing more with our other dogs and appears to be in less pain. One think I believe is with herbal supplements you have to give them time to build up and work. We didn’t see much after the first bottle but saw our dogs behavior becoming more playful so I ordered two more bottles and close the end of the second bottle was when we saw visible changes in his tumor size and noticed the very hard mass becoming softer. We are now a year into his diagnoses and he is improving. We will continue to use this supplement and hope to continue to get time with our beloved dog.

This past February, I received the devastating diagnosis that my 10-year-old yellow lab has hemangiosarcoma. She was given 1-3 months to live at that time. After reading the information provided on your website, and speaking with my veterinarian, I added Dissolve Mass (Stasis Breaker) to the daily regimen of Turkey Tail and Yunnan Biayao she has received for the past 8 months. My veterinarian and I are thrilled that she continues to thrive and shows no symptoms common with this type of cancer. I highly recommend this treatment!

Our beagle mix was diagnosed with a pretty large abdominal mass over a year ago. We immediately started her on the liquid Disolve Mass and Yunnan Baiyao, as well as Turkey Tail. The mass significantly shrunk. We stopped the Mass Disolve and Yunnan Baiyao when Sandie was doing well. We noticed the mass appears to be growing again, we’re back on the Mass Disolve and Yunnan Baiyao, praying it works again. Sandie is 15yrs old so praying for a miracle, God is good. I will post an update later

Two years ago our fur baby was given a few months to live. We began giving her Yunnan Baiyo. She has been doing great. A few months ago she had a reaction to her vaccine that I believe triggered her immune system. A mass appeared at the injection site. We began giving her dissolve mass as well. She is again responding well. The products are incredible and effective. Our family is so grateful for the extra time with our furry baby that Yunnan Baiyo dissolve mass has given us. Thank you 🙏

Can't really tell if it's doing anything or not. We are using this in conjunction with the Yunnan Baiyao. Our pup is still here, although he has a large upper abdominal tumor. Wasn't supposed to make it past the end of October, but here we are towards the end of March.

My German shepherd needed emergency surgery because her spleen had ruptured. She lost 2 GALLONS of blood when they began the surgery. The day after the surgery she was 10 lbs. lighter, that’s how much blood was in her abdomen along with the massive tumor and spleen. She survived the surgery but was weak and still had some bleeding but the vet couldn’t determine where it was coming from. The prognosis was not good. A friend told me about Yunnan Baiyao. At that point I was willing to try anything to help save my girl. After 24 hours giving my girl the prescribed dosage suggested by my vet, the bleeding had subsided by 60%. By the next day the bleeding had all but stopped. I gave her the dosages for about 10 days and she was doing really well. I then stopped giving her the capsules. About 6 weeks later she wouldn’t eat and was very lethargic. I thought this was going to be her final day, I would not let her suffer and the vet said there was nothing they could do for her. I thought of the supplement and gave it to her. Within a few hours she ate some food and walked a bit. By the next morning she was back to her old self. I will now keep her on the supplement for life as the vet suggested. I don’t usually write testimonials but I truly believe this herb has saved my dog’s life twice. And, I have been told by several friends this herb helped their dogs as well.

Trying this for our 7 y/o GSD recently diagnosed with hemangiosarcoma after a ruptured spleen. We are foregoing chemo as treatment to maintain his quality of life. The reviews for the Mass Dissolver are promising. Using this in conjunction with Yunnan Baiyao.

I am a veterinarian, have been in practice since 1977. My 11 year male labrador was diagnosed with splenic hemangiosarcoma in early December. I elected not to do surgery, but to manage his quality of life as best I could. My friend, an Equine Vet, recommended the Yunnan Baiyao, she had had good luck with it in her personal dogs, and horses in her practice.
He started getting more lethargic and depressed, and I ordered some of this product for him. I could not find any of the the local practitioners who had any on hand, so I had to order from the website. My dog was at the point where each night when I went to bed, I prayed that he would wake up the next morning. He was getting paler day by day, and not eating.
When the capsules arrived, I gave him 2, and within a few hours his color, attitude, and appetite were better.
That was about a month ago. I have had to use the "rescue pill" twice, but he is still doing well, and has many days he is normal.
I cannot tell you how happy I am to have these extra days with him. He has been my best friend for the last decade, and when it is his time I want him to go peacefully.
I only wish there was someone who could give me more guidance on the number of capsules and frequency, as the accompanying material doesn't seem to advise how many capsules, give capsules for how long, are there other products that may help support him.?

Thank you for making this product.

My dog has hemangiosarcoma (cutaneous type) with possible metastatic progression to heart as Vet saw mass there on X-ray. Yunnan saved his life initially & Solitary Hermit really helps his arthritis so I decided to try Dissolve Mass. Within a week he showed increased energy & ambulation, spirits seem higher too. I am grateful for the benefit of Dissolve Mass and the other two Best Natural Pet products without the side effect of Western Med RX’s (especially the narcotic/sedative ones) We are really enjoying & appreciating extra quality days together.

We started our dog on these and she turned back into a puppy. She was very lethargic and not eating, we found she has a tumor on her spleen. She is eight and we decided to try this rather than putting her thru surgery. To say she’s doing better is an understatement. She is responding quite well and we will continue using as long as we have this result. Impressive

Was promised it would be monday and now through USPS the label's been cancelled ...The product's not even here for a dog who's got terminal cancer. This is absolutely unacceptable. You pay for a service that you can't get never again will I use this company

I'm hoping this particular tinsure will help my boy. I know it won't cure his cancer, but right now he's doing really well. I also give him Turkey Tail, and Yunnan Baiyao Jiaonang.

My 13 year old dog Bella has a tumor in her nostril. It had started to bleed and she had trouble breathing. We started her on Yunnan Baiyao and Dissolve mass. Within a few days she showed improvement and after a couple of weeks she started breathing normally. She is acting like a puppy again. We're very pleased with these products.

Rocco has been through hell and back they gave me no more than a week with him that moment changed my life. I started this product with the yannan baiyao and my boy is sitting right next to me as I'm writing this. I did have the sack around his heart removed, but the tumor was on his heart and the doctor did want to touch it because where it is so I promised Rocco momy with do what ever it is so he can continue to live his happy life God is good I continue bot of these products and Rocco continues to be who he was ment to be and live ❤️ his happy life.

Doctor gave us 4 to 6 weeks and we have surpassed that. 7 weeks and he is doing great considering the circumstances! I am definitely buying more of this!

The best product my furboy was given 4 days to live 1 1/2 ago I was devastated I went home and trough all and everything away that wasn't healthy and started doing my own dog food and treats and with the dissolve mass ❤️ my boy is still here with us and I am blessed to wake up and see his tail wagging thank you Best Natural pets if it wasn't for your product I don't know where my boy will be today I know that his time is shorten but we are making everything like it's his last day ❤️ Malaroccs

Our dog was given 1 day to 3 months and she has now given us almost 4 weeks of pure joy and she is not suffering, so I believe it is helping

I believe your products are helping my Golden fight melanoma that has metastasized - he has already lived several months longer than the veterinary oncologist predicted - and he is lively and happy. Thank you!

I truly believe that this medication that was prescribed for my dog has kept him with me for the last 2 months. He is doing very well after being told he has a heart based tumor. Thank you

IF i could get it in him!! Im at a loss with my 13.5 year old malamute! Id love to say we’ve success but, hes not not taking anymore supplements! This one he smelled & said No Way! Sorry!

I placed an order last week because it showed delivery on Saturday. It’s now Monday and still hasn’t delivered. Now it’s saying Tuesday but who knows if that’s accurate. This will be the last time I order from you.

My sweet Hazel (8yo Aussie) was diagnosed with a nasal tumor end of October and the CT scan showed it was too aggressive to treat besides palliative care. They prescribed Yunnan baiyao to control the bleeding and it’s been amazing. She’s on lots of other meds and holistic food/supplements, but she’s not a month past her prognosis. Still has great quality of life.

I Believe I was blessed by a few more weeks with Jordan, This company was kind and helpful. Fast delivery and returns seem easy, Thank You

Good service

My dog was diagnosed with tumors on her liver and spleen and was bleeding internally. My vet prescribed Yunnan Baiyao, and she had improved so much in the next 2 days that I ended up cancelling the euthanasia appointment. She is back to her normal spunky self almost a month later. I have continued purchasing this product from Best Natural Pets and plan to continue. Great products, great service.
