Gut health has become a major topic in human wellness, and it matters just as much for our pets. A healthy digestive system underpins everything from nutrient absorption to immunity. At Innovet, probiotics and prebiotics are part of how we think about supporting pets from the inside out, and this guide explains what they are and how these pet supplements can help dogs and cats.
Key takeaways
- Probiotics are beneficial live bacteria that top up the gut, while prebiotics are fibres that feed those microbes. They work hand in hand.
- They are commonly used after antibiotics, during a diet change, in times of stress, or alongside mild, occasional digestive upset.
- This is nutritional support, not a cure. Choose species-appropriate strains, dose for body weight, and see your vet for ongoing problems.
01Meet the gut microbiome
Your pet's gut is home to trillions of microbes that help digest food, produce useful compounds and support the immune system. When this community is balanced, digestion tends to run smoothly. When it is disrupted, you may see loose stools, gas or a general off day.
02Probiotics versus prebiotics
Probiotics are beneficial live bacteria that top up the good microbes in the gut. Prebiotics are specific fibres that feed those microbes so they can flourish. They work hand in hand, which is why you often see them combined. One adds the helpers, the other feeds them.
Probiotics
- Beneficial live bacteria
- Top up the good microbes in the gut
- Add the helpers to the community
Prebiotics
- Specific dietary fibres
- Feed those microbes so they flourish
- Feed the helpers already there
03When they can help
Probiotics and prebiotics are commonly used to support the gut after a course of antibiotics, during a diet change, in times of stress, or alongside mild, occasional digestive upset. As with all supplements, this is nutritional support rather than a cure, and ongoing problems need veterinary diagnosis. Our gut health guide sets out the wider picture.
After antibiotics
Helping the gut community re-establish after a course of medication.
During a diet change
Extra support while your pet adjusts to a new food.
Times of stress
Travel, change or upheaval can show up in the gut.
Occasional upset
Alongside mild, occasional digestive niggles. Ongoing issues need a vet.
04For dogs and cats
Both dogs and cats can benefit, ideally with species-appropriate strains and correct dosing for body weight. Always choose a product suited to your pet.
05Food, fibre and routine
Supplements work best alongside a consistent, quality diet with appropriate fibre. A daily support such as Health Boost+ fits into an everyday wellness routine, and our guide to sensitive stomachs covers settling digestion.
06Vet guidance
If your pet has persistent diarrhoea, vomiting or other digestive symptoms, see your vet, as these need proper diagnosis rather than supplements alone.
Probiotics and prebiotics support a balanced gut, but they do not replace diagnosis. Persistent diarrhoea, vomiting or other digestive symptoms need a vet.
A balanced gut supports the whole pet. Pair a quality diet with the right probiotics and prebiotics, and involve your vet whenever digestive problems persist.
Frequently asked questions
What do probiotics do for pets?
They add beneficial bacteria to support a balanced gut, which helps digestion and overall wellbeing. They are supportive, not a cure.
When should I give my dog probiotics?
Common times include after antibiotics, during diet changes or stress, or with mild, occasional upset. Ask your vet for ongoing issues.
Are probiotics safe for cats?
Yes, when using a product suitable for cats and dosed correctly. Confirm with your vet if your cat has a health condition.
What is the difference between probiotics and prebiotics?
Probiotics are beneficial bacteria, prebiotics are the fibres that feed them. Together they support a healthy gut.
