Review for Bio Case - 12 oz. Powder (340 gm)

Works great and a reasonable price compared to the vet office.

Greatest Product Around...
February 13, 2014
My American Eskimo Toy was diagnosed over 4 years ago with EPI. She likes eating her food again, and has made a full recovery. I would not be without this product and it is all thanks to Entirely Pets. I live in Ontario, and they always ship this out to me in a timely fashion. Thanks Entirely Pets - you saved my girl!

Bio Case V - 12 oz. Powder
March 4, 2013
This product absolutely works for my dog. He is holding his weight and is happy and healthy. Kahne is seven years old. And still plays like a pup.
By Blackice76
Great product but price keeps going up
November 29, 2012
Entirely pets is a good company you can count on but they keep raising the prices on this item. If they want to stay competitive they should keep it relatively the same price. I may go elsewhere to try to find this product cheaper due to price increase that seems to happen almost monthly. This powder works great for my shepherd and I highly recommend it. Because of this she has fought back from her EPI problems and gained back 30 lbs.

Continues to Work!
April 24, 2012
I have been using this product since January 2011 and it is working great for Kahne. He is still holding his healthy weight and fills great. Howvever, the price is slowly increasing. It is still less expensive than the Vet's price, but it would be great if the cost of this product would stay down. Thank you.

necessary but a good buy

Bio Case V
February 4, 2012
Good stuff for digestive problems. Our Golden has been getting it on her food, twice a day for several years. She had stopped eating and slipped to 55 lbs. due to a Pancreatic problem. We thought we might lose her. Our vet recommended Bio Case V and she has averaged around 75 lbs ever since. Entirely Pets has the best price and the shipping was very fast.

Bio Case Believer
November 10, 2011
Our Chihuahua puppy always had a problem keeping weight on. She'd also show signs of having pancreatitis symptoms and bouts of painful episodes which we thought was in connection with her occasional stool eating. After some lengthy research, we decided to give Bio Case V a try and she's gradually putting on weight and hasn't had any painful episodes of pancreatitis. We are also diligently watching her diet and she's been on Hill's I/D can food and doing so well. We're so satisfied with this product.

The most amazing product available! It's actually why my Shepherd is alive. She has EPI and the freeze dried porcine pancreous she needs. It is costly but she's worth it. I love her!

This product does a very good job. It gives my dog a high quality of life. Because of his EPI
medical condition, without the product he would slowly die.

Keeps My Big Dog Alive
October 19, 2011
This is an excellent alternative to the pricey porcine enzymes available through a vet. It works just as well for 1/3 the cost. My very large GSD (120 pounds) was diagnosed with EPI when he was just 3 years old. He is now 8 years old and quite healthy and active; BioCase V has been a godsend for us.

my cat HATED this stuff
October 17, 2011
my cat would not touch ANYthing with this product in it, and it cost $80.00 so I tried to return it and they wouldn't refund my money so I could apply it to a prescription medicine.
not only would I not recommend this product, I will tell everyone I know who have pets to NEVER NEVER order from this company!!!
bad product,even worse company!!!!!

Great Treatment for Pancreatic Insufficiency
October 13, 2011
We used to be soaked by the Vet for Viocase V to treat our 10-year old Nicki. Bio Case V keeps Nicki's digestion stable just as well at a much more reasonable price and Entirely Pets is very reliable shipping it quickely when we are running low.

I choose this product because the price is right. This is a very costly product and Entirely pets has the best price. I have to buy this product for the rest of my dogs life.

Same results --- less money!
February 8, 2011
My dog was under a vet's care and was on prescription pancreatic enzymes. My dog was literally starving to death without the proper enzymes to break down the fats and proteins. The cost of the drugs, the office visits to renew the prescriptions, and the mandatory blood work was more than we could afford. Bio Case V has worked just as well as the prescription med and is much cheaper. She has maintained her weight and is a healthy dog. A great product! Thanks you!

I have had my Greyhound with pancreatic enzyme disorder on Bio-Case V for six years. She has maintained her weight (up to 68 pounds from 34) and her coat is sleek and shiny. It mixes easily with her food and then I let it sit on the stove for 25 minutes. MaeMae will "sing for her supper" when the timer goes off. The price makes it workable.

Best Purchase Ever
January 16, 2011
I was a little skeptical at first, but I have been using this product for the past 2 months and I am very pleased. Before, I was using the brand my Vet carries. I would recommend Bio Case V to anyone whom has a pet with Pancreatic Deficiency. This product is easy to mix. My dog has maintained his weight. This product really works! And no prescription required. :-}

Life Saver!
January 6, 2011
This product was a life saver for our dog. She was born without a functioning pancreas that ultimately atrophied leaving her diabetic as well. The savings over Viokase is huge and there was no noticeable difference. She has been using this product for over six years.
By Candy
Works just as well as viokase
August 24, 2010
I was leery of using a generic brand since we have had such good results for so long, but I decided to try it anyway because the price is so good.

Well we have been using Bio Case for 6 months and no issues at all.

I am so happy to have found a generic that works just the same.

Review for Bio Case - 12 oz. Powder (340 gm)
July 7, 2010
I was not satisfied with this product. A few days after using it my dogs skin dried out. It is nothing compared to Viokase. It is extremely dry and hard to mix up. I called the company and asked for a refund and they told me just to use more of the product and try it for longer. In this case it is true you get what you pay for. I am going back to Viokase it's expensive but at least it works and doesn't dry out his skin.
By RocketDog
As good or better than Viokase
March 12, 2010
We have used Viokase for our Jack Russell's EPI problem since 2005. In that time, we've watched as the price has steadily increased to a small fortune. The switch to Bio Case V about a month ago was no problem. Our dog was able to gain weight after the first week to the point we have cut back his feeding size (which is also saving money). I would recommend this to anyone.

life saver
August 29, 2009
My boreder collie was diagnosed with E.P.I and was given a prescription for Viokase. The problem was the cost of the supplement. I had to try something different and decided on Biocase, which, literally saved my dogs life. She was losing weight and literally starving to death. Within 10 days of giving her Biocase she made a full recovery. Thank you for such a wonderful product!!
