7 Signs Your Pet Has Poor Gut Health (And What to Do About It)

Your pet can't tell you when their stomach is off. But their body gives plenty of clues — if you know what to look for. Here are seven of the most common signs that your dog or cat may have an imbalanced gut microbiome, and what you can do to help.

1. Chronic or Recurring Diarrhea

Occasional loose stools happen. But if your pet frequently has diarrhea — especially without an obvious dietary trigger — the underlying cause may be a disrupted gut microbiome rather than something they ate. Beneficial bacteria help regulate stool consistency by managing the balance of microorganisms in the large intestine.

2. Constipation

The flip side of diarrhea, constipation can also indicate gut microbiome imbalance. When beneficial bacteria are insufficient, the gut's motility and fermentation functions can slow, leading to infrequent or difficult stools.

3. Excessive Bloating or Gas

Significant gas and bloating — beyond what's normal for your pet's size and diet — can signal an overgrowth of gas-producing bacteria in the gut. A more balanced microbiome means more efficient fermentation and less gassiness.

4. Bad Breath

Persistent bad breath in dogs and cats is often linked to oral bacteria — but gut dysbiosis can also contribute. When the digestive system isn't processing food properly, fermentation products can create odours that travel upward.

5. Itchy Skin or Excessive Licking

As covered in our earlier post on the gut–skin axis, skin irritation and excessive licking — especially of the paws — are frequently connected to gut microbiome imbalance. Inflammation that originates in the gut can manifest as skin symptoms.

6. Food Sensitivities

If your pet seems to react badly to foods they previously tolerated — or has a growing list of foods that seem to upset their stomach — this can indicate a compromised gut lining and a microbiome that is struggling to manage dietary variety.

7. Low Energy or Dull Coat

Nutrient absorption happens in the gut. A disrupted microbiome reduces the efficiency with which your pet extracts vitamins, minerals, and energy from their food. The result can be a lethargic pet with a lacklustre coat — both signs that the gut is not functioning optimally.

What to Do

If your pet is showing multiple signs from the list above, a visit to your vet is the right first step to rule out underlying medical causes. Alongside veterinary guidance, daily probiotic supplementation can help restore microbiome balance over time.

PawdyGene Pet Probiotics — with 19 strains, 10 billion CFUs, prebiotics, postbiotics, and supporting nutrients — is formulated to address the root cause of gut imbalance. Consistent daily use, typically for four to eight weeks, gives the microbiome the sustained support it needs to rebalance and recover.
