Gut & Skin
Itching
A night without scratching can start in your dog’s gut.
Shampoos, food swaps and drops all work on the skin, where you can see the itch. This is about the one place none of them reach, and what dog parents watch for when they start there.
By Dr. Christine Colamonico, DVM

There’s a sound an itchy dog makes at night. The licking. It goes on long enough that you start counting.
You’ve tried to make it go away. A medicated bath. A different bag of food. Drops from the vet that bought you a week, maybe two.
It keeps coming back, and every one of those landed in the same place. On the skin.
The skin is the last part of your dog to hear about any of this.
Why It Keeps Coming Back
You see it on the skin. It can start in the gut.
Skin doesn’t decide much on its own. It shows you what is going on somewhere else.
Nearly everything your dog takes in goes through the gut first, and a crowd of good bacteria does the sorting. They live on fiber while they work.
Thin that crowd out and the gut falls behind. A course of antibiotics can do it. So can stress, age, and a run of new foods, which is how most itchy dogs have been fed for a year by the time anyone asks about the gut.
A gut short on good bacteria can show it somewhere else. In dogs, it tends to show on the outside: the paws, the ears, the belly, the base of the tail.
Which is why a bath can take the itch away for a weekend and have it waiting for you on Monday.
Fleas, pollen and food triggers are real, and your vet is right to rule them out. Keep doing what your vet recommends. This sits underneath all of it, and it is the part nobody looks at.
The Question Everyone Asks
"But it’s a real allergy. The gut won’t change that."
If it’s an allergy, it’s an allergy, and your vet’s plan is what handles it. Nothing here replaces that.
An itch rarely has one thing behind it. This is the one nobody has looked at yet, and it’s the one you can work on at home, every day, without adding anything new to the bowl.
The Solution
A gut short on good bacteria needs 2 things
1
The bacteria themselves
One strain, named on the label, with research behind it in dogs.
2
The fiber they eat.
Bacteria with nothing to feed on don’t stay long enough to matter.
Most products give a dog one or the other. Together they have a name: a synbiotic.
The Real Problem
If you already tried an allergy chew
You were closer than you think. Most of them carry a probiotic.
The trouble is the chew around it. Flavors, binders, glycerin and sugar keep it soft on a shelf for months, and live bacteria have a hard time with heat and moisture. Right idea, hard way to carry it.
A REAL STORY
So two people went and made the plain version
Christine and Jérémy built Jope. Both went to vet school. Christine formulated it, and she still answers customer emails herself.
They wanted a label they could defend line by line, so they picked one strain with published research in dogs, added the fiber that feeds it, and left the rest out.
That’s GB-01®. A powder you twist into dinner. Four things in it, and the fourth is only there so the powder flows.
THE TURNING POINT
What one capsule a day does
Twist it open over dinner and stir. Nothing to talk your dog into, and the same dose whether he’s 6 pounds or 96.
The bacteria and their fiber go down together, so the bacteria arrive with something to eat and stay long enough to do the work.

PROVEN RESULTS
6 clinical trials on the strain

A TYPICAL JOPE STORY
What changes, and in what order
Digestion moves first.
Firmer stools, more predictable, and that is usually what parents notice before anything else.
The skin side is slower.
It changes by degrees, and you are with him every day, which is exactly why it is hard to see.
So write it down. Once a week, note the licking, the ears, the coat and how he slept. Most parents only see the difference looking backwards.
Give it every day for 4 to 8 weeks before you judge it. That is the whole ask.
What GB-01® parents say
Word for word from the product page. Most came for digestion, which is where this shows up first.

SWITCH TO GB-01®
We already tried a probiotic and nothing changed.
Worth checking what form it came in. A soft chew has to survive heat, moisture and months on a shelf. This is a dry powder in a capsule, one strain with published research in dogs, and the fiber that feeds it.
My vet says it’s allergies. Do we keep doing what they said?
Yes. Keep doing what your vet recommends. GB-01® goes alongside other medications and supplements. If your dog is on antibiotics, give it a few hours apart from the antibiotic dose.
My dog reacts to everything. What’s in it?
The strain, FOS, acacia gum and magnesium stearate, in a vegan capsule. No meat flavoring. Free from soy, wheat, dairy and yeast, though trace amounts can’t be ruled out.
My dog is picky and spits out pills.
There is no flavor to put him off. Twist the capsule open, sprinkle the powder over food and stir it in.
How long before I know?
Give it every day for 4 to 8 weeks. Digestion usually moves first. Daily is what counts.
Puppies, seniors, cats?
From 12 weeks old, puppies through seniors. Cats too, same capsule.

I give this to my cat that had mushy poop and now his poop is sold and firm. This really works thanks
I cannot say enough good things about the Jope Synbiotic GB-01 Gut Balance Probiotic. I have two Rhodesian Ridgebacks, Maxx and Lucilla, and keeping their sensitive digestive systems balanced is a top priority for our household. Since putting them both on this synbiotic, it has become an essential part of our daily wellness routine.
What I appreciate most about this supplement is the high-quality, filler-free formula. It combines clinically backed prebiotics and probiotics to truly optimize gut health from the inside out. It comes in convenient powder capsules that are incredibly easy to sprinkle right over their food, and my dogs absolutely love the taste—they devour it without any hesitation!
We have seen such fantastic, consistent results with their digestion that I recently increased our subscription to a bulk six-month supply. Knowing this formula is veterinarian-developed gives me complete peace of mind. I am actively recommending Jope to all of my friends with dogs!
I have seen a big difference in my Labrador Retriever who has had GI issues since he was a baby. His poops are firmer and he seems to have less gas and bloating. He has been on this supplement for approximately 4months. We have tried many other brands but this seems to work the best! I would highly recommend 😊
My youngest dog, Buffy, has always had issues with loose stools and an upset stomach. We had tried different supplements over the years but nothing worked. Within a week we were seeing a massive improvement in her bowel movements and now, after a month, she has almost no bowel issues. I wish I had known about Jope Synbiotic GB-01 sooner. So many years of avoidable butt washes, which she hates more than I do!
The product is super easy to use, just sprinkle and mix it into her dog food. Worth every penny.
