Royal Canin Veterinary Diet Gastrointestinal Fiber Response Dry Dog Food 4.6 5 11 11
Specialty foods made affordable. Great timely delivery considering they had to verify prescription with vet. This particular food is not carried in any petsmart anymore and it is the ONLY food that works for my dogs stomach. Not only does have this type, but it is significantly less expensive than petsmart home delivery and FREE shipping! Highly recommend. May 12, 2014
This product does the job for our greyhound's digestive system High quality food recommended by our vet. Our dog had a problem with runny stool and this worked overnight. December 2, 2013
Saved my rescue This Royal Canin fiber response is fabulous. My daughter rescued a pit/lab mix. After a few days the poor dog started bloating up and having diarrhea. We took her to one vet who thought she might have eaten squirrel poopoo....but the problems still existed. Took her to another vet and they took a stool sample. They determined that she had plenty of bacteria in her intestines and that about every 21 days it would flourish so much that is bloated her tummy and gave her the diarrhea. The vet recommended this food to help keep the bacteria under control. It has worked beautifully for three years - dog is fine and happy and no digestive problems at all. Using this food solved the problem and saved huge vet bills. Highly recommend it. March 26, 2014
Fantastic product! This food helped my 14-year-old black lab within 24 hours, amazing. My veterinarian knew to prescribe this product. I am impressed! December 28, 2013
Good for gastroenteritis My English setter mix had mucous and blood in his stool, plus diarrhea, and wound up in the ER after a particularly nasty episode. The vet recommended this food. Yes, it's expensive, but my boy is feeling much better, and his "output" looks great. October 27, 2013
My dog would not eat it Chewy's service was great, but my dog would not touch the food (so I have five or six bags of different kinds of dry food that he won't eat!) March 9, 2014
Great product My dog has gastrointestinal problems with diarrhea and a resultant disinterest in eating. My dog had an immediate turnaround with this product. She now attacks her food bowl and the diarrhea has disappeared. I am very pleased. January 12, 2015
worked for my puppy My puppy had soft stools and diarrhea for almost a month. The vet had tried other options, and then switched Maggie Mae to Royal Canin GI fiber response kibble. Her diarrhea and loose stool were much better within 2 weeks, and back to normal in a month. Really worked for her. December 17, 2014
