Probiotic seemed to help my dog by moondust from Olympia, Washington12/17/2011

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.

Product is OK by Dick04/08/2013

This product has good ingrediants, but we and the dogs liked the chewable vesion better.

Nice product, good value by Lori from FL06/12/2013

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 by Judy from Metairie, LA12/30/2012

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.

Great Product by Dor from San Diego, Ca11/09/2012

If your dog has even occasional diareah this will help keep them regular.

good value for the money by Peoplefood from Bedford, VA10/24/2012

Many of my dogs are on prescription medications. A probiotic is a must to keep them healthy. This product provides excellent value for the money.

My Vet recommended this for my 18.5 yr old cat, and I think it is very beneficial for him.

by from 08/21/2011

Our Boxer has a bad habit of eating anything - food or non-food doesn't matter, she eats it. We've fondly nicknamed her "goat-dog." And what she doesn't eat, our Akita will! Between the 2 of them, over the past 3 years we've had 3 bouts of giardia and at least 3 of clostridia. Of course, we've been lucky that at worst they've had it in tandem and not the same time.

Vetri-Mega Probiotic by Eileen from Indianapolis, IN04/26/2012

Our miniature poodle, Louie, has a sensitive stomach and the vet recommended this product to facilitate his digestion. It really makes a positive difference.

Questionable Safety by Rita10/30/2011

The product did not have the usual sealant across the top pf the bottle and there was an empy half capsuel in the bottle. I would like to return the product.

Excellent customer service by Rita01/08/2012

The customer service at Entirely Pets is the best I have ever encountered! The staff is very personable, concerned and prompt in addressing any concerns you might express. It is, without a doubt, the best on-line purchase experience I have made. I am completely satisfied with my purchase and the personal service I received.
