Good Product
They stopped making the Prozyme Powder for pets, which I purchased for years, with great results. This has been a wonderful alternative/replacement. It works equally as well and takes care of irritable bowel issues in cats. Good price for the amount of product. Smells a little fishy so the cats are naturally drawn to it and they have no issue with the taste.

It works!!!
My dog has severe stomach problems. Although he’s been on a medication that dogs are actually not supposed to be on for more than a couple months but he’s been on it for two years because it keeps him alive, this is a great supplement so that I can give him less of that medication. He’s 20 years old and he really was dying two years ago because he couldn’t keep anything in his stomach. He had constant diarrhea and he was dying. This in a combination with his prescribed medication has changed everything. Two years later and he still alive.

Works great
It was what I expected. Helps with my puppy's digestive system. This, combined with Firm Up pumpkin digestive aid. Works amazing. She had non-stop diarrhea for three weeks. This really helped. That and breaking down her food to its base components. No grains. We could add grains slowly later due to ProZyme and Firm up.

I believe this saved our pet chicken!
Our little Chubi (serama bantam chicken) is an enthusiastic eater and bound up her crop with woody grass stalks and roots. In the first few days we had to empty her crop her a few times to relieve some pressure; it was touch and go for awhile. We kept her hydrated and let her eat just enough applesauce, wet mash, and plain yogurt to keep her energy up. No matter what we did or how much she seemed to improve, she still had a large hard mass of grass in her crop about size of a ping pong ball. She was losing weight, bowel movements slowed, and we were running out of time. Nothing really breaks down the cellulose in grass so we were sure we were going to end up losing her no matter how hard we tried. Saw that prozyme has cellulase in it and it will help break down grass. Figured this out on a Sunday evening around 5pm on the 7th day of her bound crop. Started the following regimen that evening. So we put some liquid coconut oil in a pipette and gave her a few drops. (If you drop it on the side of the beak, surface tension will eventually draw it into the beak. Works with water too when they don’t want to drink.) After coconut oil, we waited about 20 minutes and fed her a pipette (about 30ml) filled with water mixed with prozyme. 1/4 tsp prozyme mixed in 8oz of water. We repeated this about every hour or anytime her crop felt dry and hard. Things started moving within 2 hours. Did this until bedtime. We expected it to take about 3 more days—but it cleared her out—the entire mass—overnight. Monday morning her crop was clear! UPDATE: Chewbi has bound up her crop twice since this first time. Prozyme has done the job every single time. If your chickens crop isn’t moving, order the prozyme and some pipettes. Mix the prozyme and dose with the pipette. I swear, this has saved her three times now. Good luck!

Helps prevent pancreatitis!
Schnauzers are susceptible to pancreatitis. I had to take my girl to an emergency vet to get hers treated. The vet tech told me that her schnauzer had pancreatitis once, and she started putting some of this enzyme powder on the dog’s food and it never had another issue. It’s been more than a year since we started using it on our dog’s food, and no more pancreatic issues!

Recommended by our veterinarian
This was recommended by our veterinarian to help our dog digest his food better. And I do definitely notice a difference with our dog. His tummy doesn't rumble as much after he eats, which means (well, I guess what it means would be up to the vet). But anyway, our dog is more comfortable, definitely. If you suspect tummy issues or especially when your dog is aging, I know digestive enzymes are more helpful to an aging dog. So consider this because our vet clinic uses this. Great stuff.

This product really works!
My 4 1/2 year old Doberman began having diarrhea out of the blue—no other symptoms, no parasites or ingestion of foreign bodies. Our vet was stumped as to why it was happening. I spent $1300 in six weeks time on vet appointments and probiotics, etc with no answers! I started looking on Amazon for something that might help my dog, and found Prozyme. The reviews were very positive in most cases, and I thought I would give it a try. Within five days of daily use her digestive tract was working perfectly again! She gets 4 cups of food per day, feeding morning and night with the recommended dosage of 1/4 teaspoon per cup of food. I can’t tell you how thrilled I am with this product—it works and it’s very economical! If you’re at the end of your rope worrying about your pet, give this product a try—-$30 for 1 lb is a whole lot better than $1300 that yielded no answers!

Excellent aid for my dog's digestion
One of my dogs is prone to loose stools more often than I would like. I've found that adding Prozyme to each meal has GREATLY decreased the incidence of loose stools and is of great benefit.
