Real dogs, real results

his poop is the most normal I have seen in 2 years

Dear Gussys Gut, my dig Hammy has been battling soft stools for almost two years. Vet visits have been frequent, we've tryed every food they've asked us to try for him. Finally I started making his food. Someone on a Bernese mountain dog site recommended Gussys Gut..I add it to his food. Between the two, his poop is the most normal I have seen in 2 years..Its got so many great ingredients so I know he's getting his nutrition. I really love this product. Thank you!

her poops are solid for the first time in years

I was introduced to Gussy's at Hollywood Feed and a recommended treat made by Steve's. My 9 year old pittie has the most complex allergies that worsen every year. I was shocked she liked the treats so I decided to go all in with Boost! She doesn't mind it and after about 10 days her poops are solid for the first time in years! I will have to stay on Boost because she is allergic to ingredients in the other products. We're very excited for this change and hope to keep seeing improvement."

Give it one to two months! It works!

My rescue American Pit Bull Terrier had slight digestive issues since I began fostering him. After using this product for nearly two months, his poop is perfect! No more soft serve. No more occasional morning vomit. No rumbly tummy. And my boy loves the flavor! I am beyond impressed with this product and even shared it with my vet who is a huge proponent of prebiotics. We will soon move on to Sustain and hope the results continue! Thank you Gussy's Gut!

Looking and feeling great!

The Boost has helped my 6 year old Vizsla rescue to look and feel his best! I've had him 4 months and 3 months on Boost. His coat is so soft, he is so playful and has stopped eating grass!

He is playing and running like never before

I have been using this for about two weeks now and Zeus LOVES IT. He is more excited about his meals and finishes it in one sitting now. I have also noticed a change in energy. He is playing and running like never before. I have been wanting to get more veggies in his diet and this is the perfect way. I love this for him. Thanks so much!

Her energy levels increased!

Our GSD is now 7months. We have fed raw since we got her at 9 weeks old. But she has had bouts of not wanting to eat, poor energy and mushy stools. We have been using Gussy's Gut for about 3 weeks now. And what a difference! After about 4 days of using it, her energy level increased, she is eating well and stools are normal. Thank you for a wonderful product!

Great Product

This product is awesome. One of my fur babies has struggled for years with itchiness and we're tried all the shots and supplements out there. This has provided a noticeable and sustained difference in his skin, coat, and overall irritation. It's well worth committing to the 90 days!

Meredith M.

Finally! Something that actually helped my dog

I just wanted to tell you that for years I have struggled with my dog, River's allergies issues of sore feet, red skin and itchiness. Then I stumbled upon Boost during an internet search for help. I purchased Boost and did the 90 days. I am very pleased with the results! I would say that 90 percent of River's issues are so much better. This is the first summer in a long time that his feet aren't so sore and red that he cannot walk and that he is not itching himself raw. He is a 10 year old American Bulldog.

My dog was so itchy

My dog was so itchy she would scratch constantly, clawing herself until she bled - she was covered in scabs and raw spots. I tried many supplements, diet changes, allergy test and some of them helped but not enough so I tried gussy's guts and after 30 days her scratching had lessened to the point that all of her scabs had healed and she was no longer wounding herself. I am grateful to have found something to help her.

Heather R.

Worth a try

We are almost through the first 90 days with both dogs and both of them are less itchy and don't lick their paws as much. So far I am pleased with the results.

This product works!

My Berger Picard, Emile, has had gut problems since about 5 months old. Youthful Grasses & Sprouts and the Boost has turned his problems around! He has normal, firm, healthy elimination and no more feet chewing! He stays on both products because it works so well for him.

Rhonda K.

This helped SO much!

My sweet Goldendoole Šuma was having a hard time licking and biting his paws due to candida overgrowth. He's only been on Gussy's gut for a couple of weeks and I already see a great improvement as he's licking and biting his paws less and less. I am hopeful that I will continue to see an improvement and am happy he's getting the most natural probiotic I've found on the market!

My little, health-challenged pup...

My little, health-challenged pup eats this with her food. She has tummy problems, joint problems, vision problems, and mobility problems. I caught her eating poop, and so I ordered the trial bag of Gussy's Gut. She has been on it for about a month. She has mostly lost her interest in eating poop now. And her tummy seems more settled. I'm grateful for the help.

Sharon M.

My dogs love it.

This stuff is awesome. My dogs love it and it has stopped them from eating grass and poop. I also had a dog with chronic loose stools. After going to vets and getting antibiotics nothing really worked. I started with boost and now continuing with Sustain had kept her stools normal. I would definitely recommended this product.

Andrea M.

I was feeling desperate...

"I was feeling desperate because my dogs were eating grass like crazy and one of my dogs breath smelled like she ate a dead rodent and had been that way since we rescued her two years ago. I had tried other supplements, ACV, you name it. Nothing helped. I decided to try Boost. I genuinely cannot believe the outcome. No more grass eating, NO MORE stinky breath!!! And my dogs loved having it mixed with their food. I am a believer in this stuff!!"

Meredith E.

Augie loves it! No more need to chomp grass or straining to poop!

My breeder, Aisha Cameron of Cedarwood Cotons, recommended I try Gussy Guts Boost for my 7 mo old Coton de Tulear puppy, Augie. He had been voraciously eating grass (and earth & bugs!), and was prone to constipation in spite of my using the usual remedies. I purchased the small size as a trial, and within a few days he stopped eating grass and his poop was, (dare I say), a lovely shade of medium brown. Gussy's Guts is not inexpensive but in Augie's view, well worth it! I'm now committed to this wonderful product.

Game-Changer for My Pup!

Since adding Youthful Grasses & Sprouts to my dog's meals 6 months ago, I've seen real changes: better digestion, more energy and she's no longer munching on grass like a lawnmower. 😅 This isn't your average probiotic - it's a fermented blend of organic grasses and sprouts that feeds the gut naturally. No synthetic stuff, just real food-based goodness. It's easy to use, just sprinkle on food. My dog loves it. If your pet's gut needs a reset, this is the cleanest, most effective solution I've found. Highly recommend!

Debra S.

My dog stopped eating poop. 😅

This has halted my dogs desire to eat poop. She no longer eats any dog poop. It's amazing. Also the grass grazing is reduced to a minimum almost gone but not completely yet! I am sure as she continues to get Gussy Gut she will eventually not be interested in grazing for grass.
