Dolfos Dolvit Stopper, 30 tablets is a product for dogs and cats with acute diarrhoea and intestinal absorption problems. The main ingredient is smectite, a natural aluminium magnesium silicate. It coats the gut lining, binds toxins and bacteria and helps reduce water and electrolyte loss. Horse chestnut tannin extract has an astringent and anti-inflammatory effect, while pectin, FOS, MOS and beta-glucan support gut flora. Dosing is simple: from 1 tablet a day for cats to 4 for large dogs.
What it is and who makes it
Dolfos is a Polish company making veterinary supplements and vitamins for dogs and cats. Dolvit Stopper is used for acute diarrhoea, as a supportive product for stomach and bowel disorders, and during recovery. It's handy to keep in a pet first-aid kit, especially when travelling.

Pros

Cons and what to keep in mind
- Doesn't treat the cause. Viruses, worms, poisoning or a foreign body need a vet.
- Space out other medicines. Smectite can bind other drugs — give them 1–2 hours apart.
- Acute diarrhoea only. Chronic diarrhoea needs investigation.
- No course length stated. Use until stools normalise.
First aid for diarrhoea
Remove the cause — new food, treats, table scraps. An adult dog can have a short 12-hour break from food, but water must always be available. Then feed small portions of easily digestible food or a therapeutic diet such as Brit VD Gastrointestinal. After the episode, a probiotic course helps — see our ProbioBona review. To compare another adsorbent, see our Presorb review.
When to see a vet urgently
Don't treat at home if a puppy or kitten has diarrhoea and lethargy, there's blood in the stool or vomit, the pet refuses water, has a painful belly or fever, or diarrhoea lasts over a day. Small animals dehydrate within hours. Worms are a common cause of recurring diarrhoea, so regular deworming matters — see worms in cats and dogs.
Who it suits
Dogs and cats with acute diarrhoea after a food change, stress, travel or dietary indiscretion, and during recovery from GI illness. Other products are in the veterinary pharmacy.
Verdict
Dolfos Dolvit Stopper is a convenient smectite, tannin and prebiotic tablet for quick help with acute diarrhoea in dogs and cats. It's worth keeping in the first-aid kit, but severe symptoms or persistent diarrhoea need a vet.
A first-aid kit for travelling with pets
Changes in water and food, long journeys and travel stress often upset digestion. A travel kit should include an anti-diarrhoea product, a probiotic, the usual food with enough for the whole trip, water, a wound antiseptic and a tick remover. Don't change food before a trip and don't give a big meal 3–4 hours before setting off — it lowers the risk of vomiting and diarrhoea. If severe diarrhoea with blood or vomiting starts on the road, find the nearest vet clinic.
