Most skin problems start somewhere else
The gut is where food becomes nutrition. When that balance slips, you usually see it on the outside first — in the coat, the paws and the litter box.
Dull coat, heavy shedding
Fur that looks tired, breaks easily, and covers the couch by Tuesday.
Unsettled stomach
Loose stools, gurgling, gas, and the odd skipped dinner for no clear reason.
Low energy after meals
Straight to the rug instead of the door — especially in older dogs and cats.
What's in the dropper
Eleven active ingredients and seven live strains in a proprietary 81.8 mg/mL blend. No corn, no wheat, no artificial colors.

What pet parents tell us
Results vary from pet to pet. Most owners start watching the coat and the stools around week three.
★★★★★
Murphy licked his paws raw every spring. Six weeks in, he's stopped, and his coat came back thick. He also thinks it's a treat, which makes my mornings easier.
MDana R. — Murphy, golden retriever
★★★★★
My cat turns her nose up at everything. This goes in her wet food and disappears. Her stomach has been steady for two months straight.
PAlicia T. — Pepper, tabby
★★★★★
Our senior lab had soft stools for a year. The dropper made dosing simple and we saw firmer results in the second week. We're on the subscription now.

Questions, answered
How long before I see a difference?
Digestion usually settles first — many owners notice firmer stools in the first two weeks. Skin and coat take longer because fur grows slowly, so give it a full 60 days before you judge it.
Can I use one bottle for a dog and a cat?
Yes. The formula is the same for both; only the dose changes. Use the chart above and draw each pet's amount separately.
What does it taste like?
Beef liver, from the liver powder in the blend. Most pets take it straight from the dropper. If yours is picky, stir it into wet food.
Is it safe with my pet's other medication?
Talk to your veterinarian first. Zoolvie is not for animals with epilepsy, kidney disease or liver disease, or for immature, pregnant or lactating animals, and shouldn't be given alongside other drugs unless your vet directs it.
How do I store it?
Keep it cool and dry before opening. Once opened, refrigerate and use within six months. Don't use it if the safety seal is damaged or missing.
How do subscriptions work?
You're charged every 30 days and the bottle ships free. Change the delivery date, skip a month or cancel from your account — no email or phone call needed.
