Why is my Dog Gassy? Common Causes of Flatulence in Dogs

There’s nothing quite like settling down for the evening only to realise your dog has produced something that could clear the room.

You look at them.

They look back innocently.

And somehow you’re expected to believe it wasn’t them.

Flatulence is common in dogs. But while the occasional bit of wind is usually nothing to worry about, frequent or particularly unpleasant gas can sometimes tell you something about your dog’s diet or digestion.

So why is your dog so gassy?

Eating too quickly

Some dogs inhale their food rather than eat it.

When a dog bolts their dinner, they can swallow more air. Some of that air eventually has to come back out.

Slow-feeding bowls, puzzle feeders and spreading meals out can help some dogs eat more calmly.

But don’t assume fast eating is always the explanation.

A change in diet

A sudden change in food can upset the digestive system.

This is one reason gradual food transitions are generally preferable.

If the gas appeared soon after changing food, consider whether the timing might be connected.

Too many treats

We often think about treats as separate from food.

Your dog’s digestive system doesn’t.

Every biscuit, chew, training reward and tasty scrap contributes to what goes into their stomach.

If your dog is getting lots of different treats throughout the day, simplifying their diet for a while may help you identify whether something is contributing to the problem.

Some dogs are naturally gassier

Certain breeds are notorious for their ability to produce impressive quantities of wind.

Dogs with shorter noses, for example, can swallow more air because of the way they breathe and eat.

That doesn’t mean every bout of flatulence should be dismissed as “just the breed”.

A sudden change is still worth paying attention to.

Could the food be the problem?

Sometimes.

Dogs can respond differently to different ingredients and recipes.

If gas is persistent, look at the bigger picture:

Is your dog otherwise well?

Are their stools normal?

Has their appetite changed?

Have they recently changed food?

Are they gaining or losing weight unexpectedly?

Are there any other digestive symptoms?

The answers can be more useful than simply blaming one ingredient.

What about probiotics?

Probiotics are designed to support the population of beneficial microorganisms within the gut.

They may be useful for some dogs, particularly when digestive balance has been disrupted, but they’re not a magic answer to every case of flatulence.

A dog with ongoing digestive problems needs the underlying cause considered.

When should you speak to your vet?

Gas on its own is usually not an emergency.

But don’t ignore it when it’s accompanied by other symptoms.

Contact your vet if your dog’s flatulence is associated with:

1. • Repeated vomiting
   • Persistent diarrhoea
   • Blood in the stool
   • Loss of appetite
   • Weight loss
   • Abdominal pain
   • A swollen or distended abdomen
   • Marked lethargy
   • A sudden and significant change from normal

A swollen abdomen combined with retching or severe distress can be an emergency.

The bottom line

A little wind is part of being a dog.

But if your dog’s digestive system suddenly starts behaving very differently, don’t just reach for an air freshener.

Look at their food, treats, eating habits and overall health.

And if something doesn’t feel right, speak to your vet.

Sometimes the smell is just the smell.

Sometimes it’s your dog’s way of telling you that something has changed.
