Avoid hairballs!
Great product! As long as my long-haired Persian cat gets this everyday, he doesn’t get hairballs!

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.

Prozyme Works Wonders
I've given this to my dogs for many years. It works wonders firming up stool and minimizing stool odor. The only thing I don't like currently is the price. It used to be very affordable, but it's quickly becoming price prohibited.

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!

An old dog's livesaver?
Prescribed by our vet for our almost 14 year-old black lab. We have concluded this keeps his digestive tract working.

Less mud butt!
Product helped my 2 german stewards atop pooping liquid mud. Poops aren't as hard as I would have hoped but at least it is formed. Dogs seem to be doing well on it.

Easy to use
We give this to our dog because of digestive issues. Prozyme was recommended by our vet. Prozyme has helped Zoey’s (our dog) digestive issues. She occasionally has an issue but has improved since starting Prozyme.

Still a great product after all of these years.
I always end of with 1 out of 2 of my Dachshunds, having digestive issues. I had a Dachshund in the past that would get blockages from his own food and it was painful for him, I tried the Science diet “ special “ food for that and it made him sick so I had to stop feeding it to him. I didn’t know what else to do so I tried Prozyme. He never had a problem again and lived to 17. One of my boys I have now, gets some kind of stomach issue that makes him eat grass like crazy to self medicate. Then he would vomit. He gets a very high quality food and I’ve tried other quality foods with the same result. He got a clean bill of health from the vet but the grazing and vomiting continued. I went back to my old faithful Prozyme, and no more grass and vomiting. Prozyme to the rescue again. They used to make enzymes for people called Tymezyme but they stopped making it for some reason, it’s a shame because that was also a great product.

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.
