Gut upsets in pets tend to follow a change of some kind: a new food, a course of antibiotics, a stressful week in kennels, or something eaten off a pavement. Probiotics are the sensible thing to reach for around those moments, because the aim is to keep the population of bacteria in the gut stable while everything else about the animal's routine is not. This one comes as a powder to sprinkle over food.

A powder is the format most likely to actually get taken, since it goes onto whatever the animal already eats rather than requiring a tablet down the throat or a change of diet. Single-serve sachets take the guessing out of how much to give, and they mean the powder stays sealed rather than sitting open in a cupboard losing potency. It is formulated for dogs and cats alike, so a mixed household does not need two products.

• Probiotic powder supporting digestive health
• Single-serve sachets, no measuring needed
• Sprinkles over your pet's usual food
• Formulated for both dogs and cats
• Useful during diet changes and after stomach upsets
• Palatable, so most pets take it without fuss

When a probiotic is the wrong answer. Diarrhoea lasting more than about forty-eight hours, blood in the stool, repeated vomiting, or a pet who is flat and off their food needs a vet rather than a supplement. Introduce this gradually rather than all at once, and if your pet is on medication or has an ongoing condition, check with your vet before adding anything to their food.

Who it's for: Owners changing a pet's diet, recovering from a bout of upset, or wanting steady everyday support for a sensitive stomach.
