5.0 out of 5 stars Clean ingredients I trust. I’m on my second container of Four Leaf Rover Protect and it’s become part of my dog’s daily routine. He occasionally gets loose stool, and since using this consistently, his digestion has been a lot more stable. I really like knowing it supports his gut and helps with detox.The ingredients are what sold me. It has wild blueberries for natural antioxidants, plus soil-based probiotics which I’ve read are more resilient and effective for dogs compared to some other kinds. It also includes chlorella and bentonite clay, which help bind toxins and support detoxification — a big plus for me since we can’t always control what our dogs are exposed to. The powder is easy to scoop and mix into his food, no issues with taste or him turning his nose up. I really trust this brand’s commitment to quality and transparency. Highly recommended if your looking to boost your dogs overall health!Variation: Size: 92.1g

5.0 out of 5 stars "Miracle cure" for my dog ... >>NOTE: This review has been 1 year in the making, as I wanted to review product after using long term. I am nearing the end of my 4th container. Currently, 1 jar lasts me about 10 weeks. (*See end of review.)<<This probiotic has been a "miracle cure" for my 4yo, 100lb Bernoodle. On a daily basis for almost 3 years, he endured very smelly, very soft, mostly-formed stools. He also suffered from severe stress diarrhea. After countless vet visits, expensive prescriptions, food upgrades & pre, pro & postbiotic supplement additions, I had all but given up on finding my dog some relief. One day while scrolling social media, I came across an obscure, albeit enlightening, article discussing "regular" probiotics vs soil based probiotics. After researching the subject, I found only a handful of brands that had soil based probiotics. I chose Four Leaf Rover's PROTECT Soil Based Probiotic brand because [1] it is all natural, [2] has only has 9 ingredients which are all recognizable and active, [3] has ZERO inactive ingredients, [4] has the most concentrated CFU counts, [5] was the best value for the money, and [6] has fantastic reviews on and off Amazon. This stuff is amazing. After about 2 weeks, I suddenly realized that my pup's stools were actually improving. By the time the container was finished (60 days +/-), his number 2's were as near to perfect as they could be. And his stress diarrhea wasn't diarrhea anymore … it had become merely airy, soft stools without the deathly smell. Plus, an additional benefit … his breath isn't stinky (in my dog's case anyway). I wish I had found this product sooner. Thank you, Four Leaf Rover for creating this miracle cure for my Enzo. Please don't discontinue or reformulate PROTECT; it's perfect as is … simple yet super effective. I will continue to buy PROTECT & 1000% recommend this product to anyone whose dog is dealing with gastrointestinal issues & hasn't found much, if any, sustainable relief with conventional probiotics. My best advice about administering though: GO SLOW with dosing … it's potent! I started with 1/4 of my dog's eventual suggested daily dose (100lb = 1 tbsp) for the first week, then increased weekly as his stool improved. It took about 6 weeks to get to full dose. *As of this writing, my boy only needs 90% of his suggested daily dose to maintain his stool quality. This allows me the flexibility to increase the dose for incidental stool issues.Variation: Size: 92.1g

5.0 out of 5 stars Working great from the first dose! Form the first day, perfect stools!!! My 10 year old Staffy is already improved, he can again eat broccoli, greens and sweet potatoes along with meat without gas or loose stools. He had been trying to eat dirt in the yard, so it made sense to choose a soil based probiotic. I look forward to his paw licking to ease off, which seems already to be happening after 3 days. This is less expensive that the other probiotic we were using that is dairy based.Variation: Size: 92.1g

5.0 out of 5 stars Good choice of probiotic helped my dog I like this product very much for my dog who has skin allergies and GI issues. She is sensitive to many probiotics and many other probiotics sent her into a frenzy of scratching and licking and affected her poops but this product’s ingredients and choice of probiotic seem to agree with her. I felt it was worth a try after reading about this company’s product. I believe this probiotic product helps her poops to be better. I’m so glad Amazon carries this product because, as a Prime member, I was able to get delivery next day so I could start her on it right away. It seems to help her digestive issues and I will continue using it.Variation: Size: 92.1g
