"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.

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!

Excellent & vital probiotics
This is an excellent probiotic & we use it daily for our dogs. Have been using it for years, just wish it were cheaper. A healthy gut is vital to health. We add this to their organic raw meals twice a day with just a splash of spring water to mix it up & our pack love their food. Definitely will buy again & highly recommend it.

My boxer loves it!
My dog loves this, he will lick the bowl each time. With all of the meds he needs to take, I'm happy that this will help his gut health.

kinda expensive- but gotta have for my pup!
love this stuff! Helps keep my pup healthy! Being soil based is the key! It's too expensive, in my opinion. But, I gotta have it soil based.So.. I'll buy again.

Smaller poop
After 3 weeks of adding this to my dogs food I notice 2 changes. 1. poop is smaller 2. One of my dogs is no longer interested in messing around with his sisters poop. I feed my dogs raw, organic or grass fed food and use a recipe that meet AAFCO standards and requirements. My dogs are Yorkies between 5 and 8 pounds. And they eat the proper amount required for their weight, once a day (copying the diet of a dog in the wild). Keeping all that in mind the 2 changes we have notice could not work on dogs that eat a regular none natural commercial diet or bigger in size. The container arrive in perfect conditions, was not open, ir broken, after reading the reviews I was worry about that. I agree with others, for this price they should at least place a tape and or seal it inside like other companies do to avoid losses when mishandled by carriers companies. Overall is a good product and is working great with my dogs.

Wanted to love this didn't get a chance.
I can't give a fair review on this product. I wasn't able to use it for the full duration. My dog had an allergic reaction to something new aside from this . My veterinarian's recommendation was to discontinue all new products I added to her diet.
