Great product
Dog doesn't mind swallowing these on her own and they don't get hard after opening the bottle like some soft chews I've tried since they're just capsules, and they keep the probiotic fresher.

I take Probiotics and I started giving them to my dog who had cancer. I now give a tablet to my 2 dogs every day. Do not know if it works but with that and the morning yogurt they seem to be doing fine.

something that finally works!
My dog has always had very loose bowels and only eats one kind of dog food and one kind of dog treat because of it. She can't eat any type of human food - still. But the only thing that has firmed up her stools are these probiotics. Now no more accidents in the house and it is easier to clean up outside. She will always be on this kind of probiotic. We tried another type which did work but not as well as this.

Improved digestions
This powder is added to all of my cat's food. It helps them keep the flora in their guts in good shape. In my oldest cat, it apparently also helped him fight off an chronic ear infection. This improves the overall health of my animals. It works well with the lysine based powders to support immune systems.

Review for VetriScience Vetri-Mega Probiotic (120 Caps)

No more gastric upsets
I started using this product for my 2 mini schnauzers on a recommendation from a friend. After using for 7 months not one episode of vomiting or diarrhea. Have not made any other changes to diet except starting Vetri mega probiotics.

The Best
I have tried several other probiotics but this one is by far the best! I would recommend this to anyone that needs probiotics for their dog. I use it for two older dogs (10 & 12) and it works great for them.

pleasant bed time
one of my girls has irritable bowel disorder and needless to say a briney hiney. she's on a homemade diet of chicken and sweet potatoes so there's no issues and she's maintaining great weight. ever since adding probiotics to her diet, her bottom doesn't wake me in the middle of the night. i highly recommend this product.

Great Product at a Reasonable Price!
Our Vizsla ate the stuffing out of a toy at 10 months old, then became a very picky eater and had frequent digestive problems. At 14 months she had surgery from what we suspect are complications from that episode. The Vetri-Mega has really helped her to get her digestive tract back in order. I compared a lot of products for quality and price and settled on this one. I usually give it with a meal, bgut if I forget, a little peanut butter on a spoon with the pill in it makes her love it.

Nice product, good value
I use this for many of my cats to help regulate their GI tracts. It seems to work and there is no problem with mixing in their food; dissolves quickly and they don't even know it is there. Fortiflora has been used in the past and some of the cats won't eat the food with that, but no problems yet with this one.

Helped my cat's vomiting problem
I have a 9-year-old cat that has had periodic vomiting episodes all his life. He would at times vomit several times a day (or all night) for several days in a row. It didn't seem to be related to what I fed him, and the vet could never determine a cause for it. I would sometimes have to give him metaclopromide to stop the vomiting. The problem seemed to be getting worse, so I decided to try the probiotics. They helped almost immediately. He still vomits sometimes, but not as often as he had before starting the probiotics. I'd say the problem is at least 75% improved, and I haven't had to give him any metaclopromide since starting them. I also give them to my 14-year-old cat, who tends toward constipation. I also give him Miralax, but since starting the probiotics I've been able to cut the Miralax dosage in half. I think anybody who has an animal with any kind of digestive problems should try these probiotics.

Probiotic seemed to help my dog
My beagle appeared to have a urinary track infection, so I ordered the Vetri-Mega Probiotic. It seemed to help her. I'm wondering if it would be okay to open the capsule and sprinkle the powder over my beagle's food for easier comsumption? Otherwise, I have to try to hide the capsule in a piece of cheddar cheese. I tried wrapping it in sliced meat, but the meat fell apart as I tried to wrap the pill.
