About NaturVet Vitamins and Supplements

Digestive Support for Pets

Gastrointestinal upsets can cause your best friend grief and impact his overall health, leading to loose stools and other challenges due to a disturbance in the gut flora. NaturVet Digestive and Probiotic supplements help restore microbial imbalance and promote GI health in your pet by providing the healthy digestive enzymes, gut flora-feeding prebiotics and probiotic microorganisms your pet needs.

How Digestive Enzymes Help

Digestive enzymes aid in the breakdown of food and proper absorption of nutrients for better and healthier digestion. Enzymes like alpha-amylase for starch, protease for protein, cellulase for cellulose and lipase for triglycerides play an important role in how the body breaks down and metabolizes food. Supplementing these enzymes can help make digestion easier for a challenged pet.

Prebiotics Vs. Probiotics

When a GI imbalance occurs, it usually means there are too many bad bacteria and not enough good bacteria in the gut. Probiotics like bacillus coagulans and bacillus subtilis help restore good bacteria to the gut, while prebiotics like fructooligosaccharides provide a food source so they can flourish. Giving your pet a combo of pre- and probiotics can help quickly restore balance after an upset.

Digestive Supplements

NaturVet Digestive Enzyme supplements contain a mix of essential digestive enzymes, prebiotics and bacillus coagulans probiotics to encourage gut balance, good digestion and overall GI health. They’re vet formulated and recommended for food transitioning, sensitive stomachs, flatulence and when recovering from illness.

Advanced Digestive Supplements

NatureVet Advanced Probiotics and Enzymes supplements contain bacillus coagulans and bacillus subtilis PB6 probiotics, which can survive the whole GI tract to promote optimal balance. Digestive enzymes in the formula help break down food for better digestion, too. They are ideal for pets with more severe imbalances resulting from illness, antibiotics, deworming, diet change, or other stressors.

Questions & Answers

Will this help cut down on flatulence?
Answer by ChewyFeb 04, 2018
The probiotics can help with flatulence.

Instructions on this page say 1 tablet per day (my puppy is 15lbs) On my container it says per meal. I don’t want to give too much. Would someone please clarify?
Answer by ChewyApr 18, 2019
This product is intended to be given per meal. For every 20 pounds, feed 1 chew every meal -- dogs 1-20 pounds received 1 chew, 21-40 pounds receive 2 chews, 41 - 80 pounds receive 3 chews, 81 pounds and over receive 4 chews.

Will this help stop my dog from eating animal feces?
Answer by ChewyJan 11, 2018
For stool deterrents, please view the product titled "NaturVet Coprophagia Deterrent Plus Breath Aid Dog Soft Chews" on our Chewy website.

Excellent Product!!

My two Maltese have had skin problems for over a year now. Both had yeast infections. I’ve been fighting these infections, changing foods, soaps, using ointments, probiotics, etc. I did some research on the different enzymes and found the ones in that are the best for dogs bc their stomachs don’t break them down like the others. So I gave these a try. Been using these over a month and their skin is healed. Took them to the vet and he said they look great! If you are looking for a good probiotic, this is it! I highly recommend!

Observable results!

My girl struggled with diarrhea/loose stools for years. I managed it with diet, added pumpkin powder (made into a gravy), and when at its worst, medication (under vet's direction). None of these were permanent fixes. Research led me to probiotics, and I thought my first choice of a brand was a good one, but didn't see any difference. I switched to NaturVet and the change has been incredible. Casey has been on this product several months now and she's had nothing but perfect poops! The only reason I'm not giving five stars is that other than the first order, every other jar the chewies were not chewy at all. The packages have been well-sealed, yet the treats are hard and dry, seem quite stale. Casey's a food hound so she doesn't mind, but they're advertised as "soft chews" and what I've gotten the last few months are anything but. However, as long as Casey continues to have perfect poops, I'll keep ordering these probiotics.

Works miracles

My baby (12-lb Schnoodle) has a very sensitive tummy and is a *very* picky eater. I have to freeze his kibble (to keep it from going rancid), soak the next day's portion overnight, add homemade food, add pumpkin, and STILL at times there are issues. When I hear his stomach make noises, I know it's going to be a struggle at the next mealtime to get him to eat anything. Enter these ENZYMES, and wow, what a difference they make! I ran out once and just resorted to adding kefir and pumpkin to each meal, but it just wasn't enough for his belly to be able to cope. He has much less trouble when I'm consistent with these chews, and he even eats more than usual (which has been great because he had unfortunately lost a pound at the last vet visit when I had stopped giving him these). I truly believe they make the difference! Less tummy grumbling, and it's worth it enough that I buy the big container and give with every meal, not just on an "as-needed" basis.

I want to ask if Chewy is still associated with Marshal BR ? If the answer is yes as the owner of an E Beagle I shall not be ordering any further products from you until the situation changes.

I purchased this to give to my dogs, and after opening it, and only having an open a few days keeping the lid on it. It is all dehydrated and clumped together in the little individual. Chews are just ruined. Crumbled to powder stuck together I’m very disappointed

Can’t even get my dog to try them

This product is probably a good product and provides the health benefit it claims but I’ve tried several times to give them to my dog and he turns his nose up and walks away. I even tried crumbling some of them up and putting them into his canned food. Then he turns away from his food. I’m looking for another alternative now.

Great Pre-Probiotic

This is a chewy pre-pro biotic I got for your new puppy. He loves that is chewy and he likes the flavor. He actually thinks they are a treat! Winning! Recommend to help keep you dog digestion balanced.

Unsure of its doing anything

My 60lb GS eats them if I mix it with her food. She has a very sensitive stomach and constant diarrhea if anything is changed in her diet. We have been using it daily for almost 2 months and haven't seen much of a change in her stomach sensitivity we will keep using them and update if there's a change.
