VetriScience Extra Strength Gut Health (new name, same great Vetri Mega Probiotic formula) is a non-dairy probiotic formulation produced from a natural source of beneficial microorganisms and prebiotic fiber to support digestive tract health. The probiotics in Extra Strength Gut Health are beneficial microorganisms that help control the balance of the digestive system, which is essential for improving digestion and supporting balance in other areas of the body, like skin and brain health. They also help reduce gas and discomfort in the gut and help to produce B vitamins and important enzymes. This formula also includes Fructooligosaccharides (FOS), a soluble fiber and prebiotic which can support the growth of beneficial microorganisms. Easy-open capsules provide a simple way to support dogs and cats with digestive health issues and allow for a cleaner alternative for pets with allergies or dietary sensitivities. Capsules can be given directly, opened and sprinkled, or hidden in another treat. Extra Strength Gut Health is recommended for normalizing digestion, promoting regularity and a healthy gut microbiome, helping to soothe gastrointestinal challenges, and supporting a healthy immune system.

Recommend for cats who love cheese and pukes a lot
My cat used to love to play and get pets, but recently became aggressive towards us and the other cats. The vet said it could be an underlying condition. We noticed our cat eats his food way too fast, thus causing him to puke a lot. He also loves human cheese. I started giving him this chewable once a day, and he turned back into the lovable cat. Not aggressive, plays, seems happier and loves pets again. He has no problem eating them.

Keeps my English Bulldog’s skin happy
Give it a try, it might be what you are looking for. I have waited almost a year before I gave a review just to make sure I believed in the product. So here is my backstory: I have a 3yo English bulldog who loves to live outside in Nebraska and has horrible skin issues. He naturally has a nasty yeasty smell. As a 1yo, we started him on depo shots because he chews his feet and gets hot spots. It helped some. By 2, it wasn’t doing much, and he was getting face infections, so the vet put him on Apoquel. It was a game changer, his skin barely had a smell to it, and he seemed less itchy. Now, by this time, I was also bathing him twice a week with medicated shampoo, shaving him in the summer (to help air get to his skin better), and washing his face daily with medicated wipes. Things were going ok, but he had that rust colored fur on his face and feet, and had started chewing his feet again. The vet decided to give him depo shots as well, but they didn’t seem to help much. We saw an ad for dog probiotics and I looked into ones that were for dogs with itchy skin. I chose this one, and I am extremely happy with it. The rust color is now totally gone from his face and feet, he has not chewed his feet since I put him on it. He did get a few small hot spots one time, but I hadn’t given him a bath as soon as I should have. I only wash his face once in between bathing him and he has not gotten any face infections. He is still on the Apoquel, but I am not taking him off that after experiencing what he was like before. I can not attest to how every dog will react, but try it, and give it time, he didn’t change overnight. It takes awhile for these probiotics to work. I have used several bottles now, I have noticed he gets a little diarrhea for a couple days about 2 weeks into a new bottle, or its a fluke that has happened 3 times now. I have definitely seen a difference in him and will continue using it. His skin is much happier and so is he.

Quick and simple my cat loves them
This is my first time trying anything from VetriScience, so I can’t compare it to older versions, even though I did receive the previous packaging instead of the “new look” advertised. It doesn’t smell off or old, so I went ahead and tried it with my cat.He absolutely loves the chews, so no issues getting him to eat them at all, which is a win. As for effectiveness, it’s a bit hard to judge since I’ve just started using them. I have noticed he hasn’t been puking as much lately, which is a good sign for me. He’s still under 2 years old and also eats a hairball control/urinary tract food, so I can’t say for sure what’s helping the most. I put some water additive in his water as well which helps soften his stools.What I really appreciate is the convenience. This is way easier than giving him pumpkin purée, which honestly works great but takes more effort. I’m often too busy to portion it out, and I end up wasting a lot from the can. Freezing it in cubes helps, but then I have to thaw it and it’s not always practical. These chews save me that time and mess, which is a big plus.Price-wise though, this is also more affordable than other probiotics I’ve looked at, so it’s budget-friendly too. I’m also considering trying the Purina probiotic powder in the future for comparison. But for now, this has been a great quick and more affordable option.

Hero of a product for senior dog, unexplained diarrhea
An incredible product! My senior shepherd mix has been on this for almost 2 years. She was 13 when she started having unexplained diarrhea. We ran all of the tests and changed her diet in multiple ways and everything came back negative or didn’t work. Finally, I decided OK maybe her microbiome needs support with a probiotic. The bacteria in our guts are essential and maybe her age or an undiagnosed issue had changed the way the bacteria in her gut were functioning. We put her on this product over others on the market because of the multi strain composition. Each type of bacteria provides a potential function our dog was most likely missing. It didn’t make sense to give her a treatment with only 1 strain and 1 function when we could give her a pill with multiple strains and functions. After a single day on this pill back in 2023 she was a changed dog. Her stools were solid, she excreted a crazy mucus layer that I didn’t expect, and she was more relaxed and comfortable than she had been in 6 months. We have kept her on this twice daily for the last 2 years and swear by its ability to promote healthy gut conditions. Definitely keep this product cold in the fridge. It is probably also oxygen sensitive so by the end of the bottle the last 1/3 seems to be less effectivenand we double up pills. But what a hero of a product. I’m sure this has contributed to her great state of health now at 15 years old where she is still so active and loving life.

Every time the change of season occurs, my 100% indoor cat has issues with excess fur, leading to gut/bowel movement issues. This stuff works a treat, but alas, It seems to be out of stock and no one else seems to stock it in Oz. If it comes back, buy it. If your cat initially does not eat the whole thing.. break up and put on their wet food.

Super! Not exactly cheap, but after getting a super skinny poorly rescue dog with some really unhealthy bowel movements, someone recommended pro-biotics for him. So, seeing as it is a medication and not cheap I did some serious and lengthy reading and research! I found this product seemed to be the only one with evidence that the bacteria reaches the gut, or in fact even contains active bacteria, most products only contain yeast and other chemicals to encourage gut health. Anyway, after extensive reading decided this was the product for my boy. He was struggling to put on weight, and like I said earlier, his bowels were far from healthy and there was the occasional incident of him eating his own poo (I know, revolting, I was horrified, but again, reading and research – it’s actually a natural habit that’s formed with dogs evolving as scavengers, and they will eat literally anything containing undigested protein and goodness, and doing this is symptomatic of deficiency of something in the diet or a problem where food is not being digested by the gut properly). He’s been on two a day (as he’s a big boy and that’s the recommendation dose for his weight) for about a month now, and he has been putting weight on at a much healthier rate, and his bowel movements are so much healthier, I’m definitely going to continue him on them as the evidence out there suggests they are genuinely helpful for dogs, and they’ve definitely stabilised my boys bowels!

Works well to clear up digestive issues.

Je suis très heureuse que mon chat aime ces suppléments puisqu’il a des problèmes digestifs et c’est important qu’il consomme des probiotiques pour sa santé. Le vétérinaire a prescrit d’autres marques mais mon chat refusait de les consommer. Avec ceux-ci, il accoure dès que je sors le sac.
