About This Item

Details

  • Helps relieve diarrhea or loose stool, replenish electrolytes to aid in dehydration recovery, and provides a protective coating to help calm the digestive tract.
  • Formulated with pectin and kaolin to help increase the bulk and slow down the passage of feces, Pet Pectillin also works to alleviate irritation, discomfort, cramping, and toxin absorption.
  • The thoughtful formula is highly palatable and easy to administer.
  • To use, shake well, then apply directly into your pet’s mouth every four hours or mix with food; for pets weighing less than 5 pounds, consult a veterinarian.
  • Consult with your veterinarian for dietary advice—this supplement is intended only for dogs and cats and is not made for human consumption.

I've tried this product on a cat and a dog and it worked on both animals. The dog had tummy upset so I thought to give him this instead of fortiflora as this is cheaper and it worked for him! Back to eating his food, no throwing up foam or bike, diarrhea. Highly recommend just keeping it on hand just to have in case you need it for your pet.

For a dog that gets into all sorts of things and has a sensitive stomach, this is a must. we keep on hand for when her tummy gets out of sorts. I dont think it tastes great but also dont think it is terrible bc we got one dog to eat if on food.

Although I haven't used this promo yet, I give 5 stars, because of the ingredients being specifically for dogs. I had to use human anti diarrhea medicine while my senior pup had bad diarrhea during the weekend, and where we live, we have no 24/7 emergency clinic. Between that, but mostly the plain pumpkin I gave her...she had great stool come Monday. I hope I don't need to use this for my Lacy. But am grateful to have it on hand if needed . Will definitely update rating if I need to use...and how it works.

Not the right choice for my baby boy.

I do not like this brand for my little boy when he is sick. I think, it has entirely too much calcium in it for a dog my size. My baby is only 6-7 pounds. Maybe, it would be an excellent choice for larger dogs; but not one my size. I donated, all of the containers I purchased to the Humane society in my area to help with larger dogs.

This product is a must have to have on hand at all times. I have two dogs who will eat anything they find and 4 grandkids who never disappoint them! This product works fast and is safe to use. I do administer it with a elongated measuring spoon as it is very thick so you want something with a large opening to get it in their mouth efficiently but they don't seem to mind it at all..

So many choices out there to help settle a cat's digestive system and this one does as described. I have a cat with IBD issues but is also diabetic so the canned food he eats to control his diabetes also messes with his IBD issues. Adding this product to his regiment has changed all that. His stools have become normal. Highly recommend.

My little lady, a Yorkie, had been feeling bad for a week or so and having runny accidents on the carpet. After only one dose, she was feeling better the next day, playful, and back to her regular toileting outside.
