I usually order the 12 oz. powder and it last quite awhile. And the powder mixes well with my pets food. He loves his food. The capsules were not working out so well. Too inconvenient.

Since my dog has been taking Bio Case V, she has a much better appetite and more energy.
She was going out several times a night before, now it is only a couple times a week that she needs to go out at night. Its like having our old girl back again.

We own a German Shepherd who developed EPI at the age of 18 months. He has to have enzymes with every meal.
We tried a couple of other brands which worked but are so expensive. Then we heard about Bio Case V. Bio Case has given us entire satisfaction, our dog is now 85 Lbs, has absolutely no negative reaction to this product, and the price is so much better.
Even better thanks to EntirelyPets, because they give you 15 % off.

I have a pit/lab mix and when he was about 6months he was diagnosed with Endocrine Pancreatic Insufficiency disorder, he went from a 60lb biggg puppy boy to a 35lb skinny starving creature. It is unfortunate that there is no cure for this disorder that complicated so many dogs and cats lives these days(it all stems from not enough nutrition in their diet, from my research) so I have used MANY foods MANY enzyme products and after all the changes in names have found myself ordering BIOCASE over and over again. It is not too expensive and seems to put my 4 yr old puppy at ease. I am happy to report with some extra food and 4 pills a day he is now at a whopping 54lbs!!!!! And the shipping from EntirelyPets has always been top notch! thanks!! I have included 2 pictures of when he was first diagnosed and now when he is at a healthy weight.
