Probiotics for Dogs: What To Know and Look For

Want to keep your dog happy and healthy? Consider adding a probiotic to their diet! Probiotics for dogs can be extremely helpful, and they hardly require any effort on your part: simply feed one to your pet alongside their regularly scheduled meal, and both you and Fido will be good to go. If you’re worried about separating the good products from the not-so-good, though, you’ve come to the right place. Keep reading to learn how to purchase a high-quality probiotic for dogs in 2024.

Why Is Gut Health Important for Dogs?

The presence of good and bad bacteria (including their balance in the GI tract) is important for your dog’s gut to function properly. Healthy bacteria work with immune cells to fight off infectious viruses, bacteria, and fungi. A healthy gut also sends positive signals to the brain by balancing hormones and maintaining a well-functioning nervous system. In general, dogs feel calmer and more fit when their stomach is functioning properly.

Most of the living bacteria in dogs’ intestines are healthy, but the presence of too many unhealthy microbes can cause disease. This is called dysbiosis, and it occurs because of a recent administration of antibiotics or simply due to genetics. Dr. Linda Simon, a consulting veterinarian at Pawleaks, mentions that while we know much about the gut microbiome, we don’t know everything. Dr. Simon says: “Frustratingly, the information we have on the gut microbiome and probiotics is lacking. Indeed, this is a huge topic that scientists and researchers are only beginning to scratch the surface of. ”

Whatever the reason may be, poor gut health will take a toll on your pup’s overall well-being and happiness. I don’t know about you, but I definitely don’t want that for my dog. Symptoms of poor gut health include itchy skin, allergies, frequent vomiting, constipation, and loose stools.

The Benefits of Probiotic Supplements

Probiotics help in balancing gut bacteria. They do this by supporting good bacteria and stopping bad bacteria from growing. A healthy, active gut is able to absorb nutrients better, and the immune system also works better when digestion is improved. Another benefit of probiotics is their role in supporting mental health: just like in humans, a happy gut makes for a happy brain, and probiotics for dogs can help reduce anxiety and stress levels.

Probiotics for dogs also help treat stomach issues like diarrhea, irritation, indigestion, and inflammation. If your dog’s stool looks like my dog’s, then you should look into probiotics. When the gut is doing well, dogs are better able to avoid urinary tract infections and allergies.

How Do Probiotics Work in Dogs?

The digestive tracts of animals contain billions of bacteria that help maintain a healthy digestive environment and prevent various diseases. They also help metabolize food, absorb vitamins, strengthen the immune system, and fight off pathogens to prevent diseases and treat stomach inflammation.

Probiotics are administered to dogs to maintain the microbial balance in their intestines. An imbalance occurs because of any disease or malnutrition, but when probiotics are administered regularly, the balance is restored. Dr. Simon spoke about some common balancing probiotics:

“The probiotics we commonly use for our canine companions include Enterococcus faecium, Bifdobacterium animalis, Bacillus coagulans, and several Lactobaciillus strains. These are some of the few bacteria that have been studied in the canine model and that studies have shown may have some health benefits.” Be on the lookout for these green flag bacteria when shopping for probiotics for dogs.

What Changes the Effectiveness of Probiotics?

Not all dogs will respond equally to probiotic supplements. Factors that can determine the effectiveness of probiotics are as follows:

Age and weight

Age affects gut health, and the dosage you should give your dog will be determined by their weight.

Timing

You should carefully monitor the time between doses. Probiotics should be given to dogs at the same time each day to maximize their benefits.

Breed

No matter if you have a chihuahua or a Great Dane, a dog’s activity levels will differ depending on their breed. Various breeds and activity levels will require different probiotic formulas, so you should test out a few until you find one that works for your pet.

Prebiotics

Probiotics are important, but they’re just half of the equation. Eating food that supports the absorption of probiotics is essential, and that’s where prebiotics come into play. Prebiotics occur naturally in many fruits and vegetables, such as garlic, onion, leeks, banana, and pumpkins, and they help good bacteria flourish in the gut. Many probiotics for dogs include prebiotics, such as options made with pumpkin.

Other factors

Always pay attention if your dog’s stomach seems upset, as this can be indicative of various other health problems that may require vet intervention. If there’s a significant change in your dog’s appetite or weight, or if they’re frequently vomiting, take them to the vet immediately.

People Also Asked

Why is it important to give my dog probiotics?

External stimuli, such as a thunderstorm, travel, fireworks, or prolonged separation cause dogs stress and anxiety. Along with feelings of discontent, you'll notice a sort of hyperactivity. Probiotics for dogs help restore the gut flora, though, so that your furry friend stays calm and can better tackle daily life.

What is the best time to give probiotics to dogs?

If you're giving your dog probiotics to help with digestion, you can add them to their meal. Otherwise, the microorganisms in probiotics survive better when given between meals. You can give them soft chews along with some water or liquid, which helps dilute stomach acid so that the probiotic moves quickly into the digestive tract.

How often should I give probiotic supplements to my dog?

Regular administration of probiotics is important to maintain healthy gut flora. Probiotics for dogs come in the form of soft chews and should be given according to the dog's weight.  One soft chew daily is enough for smaller breeds up to 15 pounds, while two chews daily are recommended for dogs weighing 45 to 60 pounds. Breeds weighing more than 75 pounds should be given three soft chews.  With that said, different brands may use different formulas, so follow the specific instructions carefully to make sure your pet gets the correct dose. A probiotic overdose is not something you or your dog will want to deal with, as it can result in extreme vomiting, nausea, or diarrhea. 

What messes up my dog's gut microbiome?

The gut microbiome describes the bacteria and microbes that live in your pet's gut (their stomach and digestive tract). Your pet's microbiome changes based on the foods they eat, so if they eat bad food (food that is either unhealthy or disease-ridden), it can change their microbiome for the worse. Vomiting will also have a negative impact on your pet's gut health.

What happens if I give my dog yogurt?

Yogurt is a great probiotic for your dog. In addition to the products featured in this guide, yogurt can be helpful for your dog's gut health. Just don't give them too much, as this can have the adverse effect and lead to an upset stomach.
