Best Dog Anal Gland Supplements of 2026

The dosing chart is the argument for powder. It starts at an eighth of a teaspoon for a dog under 15 pounds and climbs to a full teaspoon over 75, so the serving scales to the animal in front of you instead of rounding to a chew count. Two dogs of wildly different sizes can share one tub, which no chew here can manage.

Each teaspoon carries 1,025 mg of pumpkin-seed and apple-pectin fiber, plus 1.9 billion CFUs of L. acidophilus against the chew's 480 million, along with bromelain, quercetin, and vitamins C and E. Sprinkled over wet food it vanishes into the meal, which is why it's the better bet for a dog that picks tablets out of the bowl. Beef liver is the flavor most dogs go for; there's also pork liver and salmon, and the label covers cats as well.

What we don't love is how fast it goes. The scoop grows with the dog, so a large one empties a tub quickly, and powder is one more thing to remember at mealtimes. Everything else is in its favor: the same fiber as the chew, a stronger probiotic dose, and a texture that can't be refused because there's nothing to chew. If your dog eats wet food without drama, this is the version we buy.

Firm stool is the whole point of this one, and the numbers are built for it: 4,100 mg of fiber per scoop from miscanthus grass, pumpkin, and carob, plus 500 million CFUs of Bacillus subtilis and 400 mg of pork plasma. The serving is a full tablespoon per 20 pounds of dog, a lot more powder per meal than Glandex's teaspoon.

That volume is why the 32-ounce tub makes sense; a large dog on a tablespoon a day is exactly who this was designed for. Firmness is also where it looks strongest against the rest of these picks, and it's the result we want first. The catch is the pork plasma: if your dog is on a pork-elimination diet, or you simply aren't sure, read the label before the tub is open. For everyone else, this is the pick when the problem starts with the stool.

If your dog has already turned down a supplement, start here. Acceptance is the strongest of any chew on this page — this is the one dogs treat as a treat rather than a chore — and when the same thing has to go down every day for a month, that beats any single ingredient on a label.

The formula is the broadest here too: pumpkin seed and sweet potato for fiber, miscanthus grass and apple fiber for bulk, colostrum, inulin, dandelion and nettle root, a six-enzyme blend, and eight probiotic strains. We're wary of long ingredient lists as a selling point, because fiber is still what firms the stool and empties the gland. But this one is built sensibly, and the digestive side is where it does its best work — it's our pick for the dog whose gut is the bigger problem, the one with soft stool, gas, or a stomach still recovering from antibiotics.

Two practical notes. It's a chicken chew, and a dog that turns its nose up at poultry will do the same here. And there are fewer chews in the tub than in most of the others on this page, so it runs out sooner in a house feeding more than one dog.

NaturVet sits at the value end of this list, and it gets there without leaning on pumpkin alone. Beet pulp and psyllium husk both swell and hold water, doing the same stool-bulking job as Glandex's pumpkin-seed and pectin blend by a different route. For a dog that scoots a few times a week rather than daily, that's plenty.

It's a pumpkin-flavored soft chew, and the texture is the ordinary kind that breaks in half for a small dog without crumbling. NaturVet has been making supplements since 1994, and this one has the plain, unglamorous feel of a product that hasn't needed to reinvent itself — a decent sign in a category full of ingredient lists written to impress.

The first week is the part to handle carefully. Some dogs bring it straight back up, and starting with half a chew inside a meal rather than a whole one on an empty stomach usually settles that. If your dog has a sensitive stomach, that's worth doing whichever supplement you land on.

What tips it for us is the pairing of a real fiber blend with a chew dogs take without a fight — the two things that decide whether a supplement is still being given in week six. If the scooting is mild and occasional, this is the sensible buy. If your dog needs expression at the vet every few weeks, a soft chew won't change that, and it's worth asking what else is going on.

A hundred and seventy chews in one tub is the reason to look at this one. It's the biggest count here by a wide margin and it sits in the budget tier, which makes it the least expensive way to run a proper trial without committing to a premium tub first. The formula is the standard build — pumpkin and psyllium husk for fiber, probiotics, and digestive enzymes — in a chicken chew labeled for puppies through seniors.

Treat it as a trial rather than a treatment. If your dog scoots occasionally and you want to know whether bulking the stool changes anything, this tub gives you a long run at it, and the chew goes down like the treat it's shaped like. For a dog already on a schedule of vet expression, guessing isn't good enough — that's a conversation with your vet, not a bigger tub.

The guarantee is the most interesting thing here. Ninety days to ask for a refund, and no need to ship the tub back — for a supplement where it genuinely depends on the dog, that's worth more than another ingredient on the label.

Underneath sits a straightforward fiber blend: beet pulp and psyllium husk for bulk, dandelion root, and pumpkin powder, in a bacon-flavored soft chew, 120 to a tub. No probiotic, no enzyme blend, and no milligram breakdown, which puts it at the pumpkin-and-fiber end of this category rather than the four-mechanism end.

We treat it as the trial option. If the scooting is mild and occasional, and you want to know whether bulk fiber alone changes anything before paying for probiotics and quercetin, this does that with a refund attached. If it works, there's no reason to move on to something more complicated; if it doesn't, you've spent time rather than money.
