You love everything about your dog… Well… almost everything.
Truth be told, you could do without the foul-smelling farts that can kill a mood and clear the room.
Of course, just like people, dogs pass gas. Sometimes loudly, sometimes silent but deadly. And lots of things can cause stinky dog farts, like new food, speed eating, or chewing on your old pair of running shoes.
While it’s quite normal for your dog to fart occasionally, excessive smelly gas can be a sign of a larger concern—one that requires your attention and intervention.
Why Does My Dog Fart So Much?
If you had to guess, what’s the most common cause of dog farts?
- Gluttony or compulsive eating
- Eating shortly after exercise
- Diets high in non-organic or GMO ingredients
The answer?
Many dog owners are surprised to find that the #1 culprit is CHANGING what their dog eats.[1]
So if you switch brands or flavors of dog food, or add something new that they don’t normally eat, the gas will flow...
NOTE: Food changes also include anything your dog gets into—from trash to deer poop to table scraps.
Building on that, ongoing and/or chronic farting tends to be caused by hard-to-digest ingredients, which include:
- Dairy products like milk and cheese
- Soy products
- Corn
- Peas
- Beans
- High-fat foods (like cat food or bacon)
Interestingly, right behind dietary change is another leading cause of dog farts: speed eating.
When your dog wolfs down their meals, they introduce a lot of air into the digestive tract. That trapped air needs to get out somehow… and farting is the easiest pathway out.
As common as both of these issues are, food changes and speed eating can really do a number on your puppy's intestines. More specifically, it can really mess up the balance of good and bad bacteria in your dog’s gut microbiome. And that can make your dog (and you) very uncomfortable.
Is It More Than Just Gas?
If your dog farts almost constantly, or if the farts smell excessively bad, it could be a sign that your dog is dealing with more than just gas. So you’ll want to keep your nose peeled and your vet on speed dial. Here’s why...
An overly gassy dog could be dealing with:
- Food allergies or intolerances
- Inflammatory bowel disease IBD)
- Irritable bowel syndrome (IBS)
- Leaky gut
- Small intestinal bacterial overgrowth (SIBO)
Once your vet has pinpointed the cause of your dog’s noxious gas and other symptoms, they’ll come up with a treatment plan to help. And that plan will almost always include targeted gut support.
The Best Thing You Can Do to Address Stinky Dog Farts
Your dog has a gut microbiome, just like you do. It contains trillions of bacteria, including beneficial probiotics and harmful pathogens.
When your dog’s gut microbiome is in healthy balance, probiotics greatly outnumber pathogens. But when it falls out of balance, those harmful bacteria grow and multiply out of control. That condition is called dysbiosis, and it can cause all sorts of gut health issues for your dog[2]… including very smelly gas!
Luckily, giving your dog specific gut support in the form of a probiotic supplement is a proven safe way to balance your pup’s gut microbiome and soothe their GI discomfort.[3] And when your dog’s gut is in healthy balance[4], they’ll sit up and bark for joy.
Plus, new research shows that the right probiotics—meaning specially formulated for your pet—can transform your dog’s gut health.[5]
Dog Probiotics: What Strains Are Most Effective
Probiotics can work wonders for your dog’s smelly gas problem. But you want to make sure that you use a probiotic that’s been proven to help resolve this issue in dogs. Luckily, you don’t have to guess which probiotic strains will be most effective...
In a 30-day clinical study, a specially formulated spore probiotic offered significant relief for dogs suffering from GI issues.[6] That supplement contained two dog-specific probiotic strains: Bacillus subtilis and Pediococcus acidilactici.
To test that probiotic, researchers worked with two groups of dogs: one group with gut dysbiosis experiencing uncomfortable symptoms and one group of healthy dogs with no GI issues. All 11 dogs got the spore probiotic for 30 days with highly positive results:
- GI issues were dramatically reduced or in some cases disappeared
- Markers of leaky gut decreased substantially
- Farting was reduced even in healthy dogs
- No healthy dogs experienced negative side effects
The bottom line: These targeted pet probiotic strains helped reduce gas and other uncomfortable symptoms in healthy dogs and in dogs experiencing GI issues. And that means breathing easy around your best friend is now within reach.
