Common signs your dog or cat may need probiotics include digestive issues, changes in appetite, and gut imbalance. If you notice these symptoms, early support can help restore healthy digestion.
A happy, energetic dog starts from the inside out – and that begins with a healthy gut. Just like humans, dogs and cats rely on a balanced gut to digest food, maintain a strong immune system, support a shiny coat, and even keep their mood stable.
But how do you know if your dog’s gut needs a boost? Frequent digestive upsets, itchy skin, or unusual behaviour could be more than just a minor annoyance – they could be signs your dog is missing the powerful benefits of probiotics.
In this guide, we’ll show you 10 signs your pet's needs probiotics, what probiotics actually do, and how to tell if they’re working – helping your furry friend feel their absolute best.
1. Upset Stomach or Diarrhoea
Frequent loose stools or diarrhoea may indicate an imbalance in gut bacteria. Probiotics can help restore balance and reduce the frequency or severity of digestive upset.

2. Excessive Gas or Noisy Stomach
Persistent flatulence, gurgling, or rumbling is a sign that digestion may be off. Probiotics can help improve nutrient breakdown and reduce gas.
3. Irregular Bathroom Habits
Alternating between constipation and loose stools often reflects gut imbalance. Regular probiotics may help normalise bowel movements.
4. Difficulty Maintaining Weight
Weight loss despite a healthy appetite could indicate poor nutrient absorption. Probiotics aid digestion and help your pet get the most from their food.
5. Itchy Skin or Poor Coat Condition
Red, itchy skin, dry flakes, or patchy fur may be linked to gut health. Since much of the immune system is in the gut, probiotics can indirectly support skin health.
6. Recurring Yeast or Ear Infections
Frequent yeast infections or ear issues can signal an overgrowth of harmful bacteria. Probiotics may help restore balance and reduce recurrence.
7. Anxiety or Behavioural Changes
The gut-brain connection isn’t just for humans. Digestive issues can affect your pet’s mood and behaviour. Probiotics support a healthier gut, which may reduce anxiety.
8. Diet Changes or Eating Mostly Kibble

Switching foods or feeding dry kibble can stress the digestive system. Probiotics help the gut adapt to diet changes and improve digestion.
9. Weakened Immune Response
Frequent illness, low energy, or slow recovery can indicate immune strain. A healthy gut supports immune function, and probiotics can strengthen natural defences.
10. Bloating or Discomfort After Meals
Pet's that appear uncomfortable after eating may struggle with digestion or gut imbalance. Probiotics can help reduce bloating and improve nutrient absorption.
