Probiotics for Dogs Benefits

Probiotics have proven beneficial for treating a vast array of dog health problems — this is part of the reason that many people are excited about probiotic supplements for dogs.

A few of the most common ailments they’re used to treat in dogs include:

Dog Probiotics for Diarrhea / Excessive Gas / Digestive Upset

Digestive problems – especially dog diarrhea – are the most common reasons that probiotics are administered to dogs.

Often, dogs suffer diarrhea because the naturally occurring beneficial bacteria in their intestines have died off.

This not only prevents proper digestion, but it also allows harmful bacteria to proliferate – both of which can cause diarrhea and other digestive problems, such as excessive gas.

But, by administering a good probiotic, you can restore the beneficial bacteria that should be present in your dog’s intestines, which will usually solve the problem.

The bacteria will not only help restore proper intestinal function, but they will help out-compete the harmful bacteria, so your dog’s body can eliminate them.

Dog Probiotics for Skin and Coat Health

Bacteria play important roles in a variety of biological systems.

So, while probiotics are normally used to help solve problems involving the digestive system, they can also help solve problems that appear to have little to do with the digestive tract. One good example of this phenomenon involves your dog’s skin and coat health.

By administering probiotics to your dog, you help ensure that his digestive tract is functioning properly, which, in turn, will often help improve the condition of his skin and coat.

It also reduces the chances that harmful bacteria will colonize your dog’s skin, as fewer harmful bacteria will be found in your dog’s digestive system (because of the way dogs groom themselves, they’re likely to become coated in any bacteria found in their intestines).

Supplementing Dog Probiotics to Boost Immunity

A large portion of your dog’s immune system resides in his digestive tract. This helps to ensure he doesn’t become sick if he eats something contaminated with harmful bacteria.

By administering probiotics to your dog, you can help support his immune system, thereby helping to protect him from threats.

Dog Probiotics May Improve Yeast Infections

Yeast infections can be extremely troubling medical conditions, which cause constant and severe itching.

Some also cause skin irritation or pain, and – depending on where they occur – they can even cause your dog to develop terrible odors.

Serious yeast infections may require anti-fungal medications to treat, but probiotics may help alleviate mild cases.

Yeast infections often occur because the beneficial bacteria living on or inside your dog’s body die off. This creates an opening for yeast organisms to move in and colonize your dog’s body.

But, by administering probiotics to your dog, you can help restore the populations of beneficial bacteria, which will then out-compete and supplant the yeast organisms.

Skin Allergies

Skin allergies often occur in response to allergens present in the environment, but for reasons nobody quite understands, probiotics often help to alleviate them.

It may be that by adding beneficial bacteria back to your dog’s digestive tract, you can help “reset” a dog’s immune system and stop it from overreacting.

Regardless of the reason probiotics help to treat skin allergies, they are safe, easy to administer and natural, so they’re often worth trying.

When Switching Foods

Anytime your dog switches foods, it can upset his stomach – particularly if you don’t transition between the two foods slowly enough.

Among other things, an abrupt switch in your dog’s food can wipe out the bacteria present in his intestinal tract, causing him to suffer diarrhea and excessive gas.

But, if you administer probiotic supplements while changing your dog’s food, he’s much more likely to remain healthy while making the switch.

Note that beneficial bacteria are a normal part of your dog’s gut flora, so there’s no reason you shouldn’t give probiotics to your dog (unless, for some reason, your vet advises against it).

Even if it turns out that your dog already has a healthy population of beneficial bacteria in his intestines, any excess bacteria will just pass through his system.

So, dog probiotics are high-upside/no-downside products that are almost always worth considering for your pet.

Other Benefits of a Dog Probiotic

A few of the other reasons people often administer probiotics include:

  • Loose stools
  • Bacterial infections or imbalances
  • Inappetence
  • Constipation and painful or difficult eliminations
  • Chronic vomiting
  • Lethargy and depression
  • Poor growth or weight loss
  • Food allergies
  • Hot spots and hair loss
  • Some types of inflammation

Are Probiotics Good for Dogs?

Healthy dogs (and most other animals) harbor an entire microbial ecosystem inside their digestive tracts.

The vast majority of these bacteria are either beneficial or fail to have any appreciable effect on the dog’s health.

The beneficial bacteria perform a number of important functions, such as assisting in the digestion of food and maintaining a proper pH in the digestive tract.

However, these beneficial bacteria can be wiped out by a number of different things.

Broad-spectrum antibiotics, for example, often kill off these bacteria, while poor-quality dog foods may fail to provide the crucial nutrients the beneficial bacteria need to survive. In either case, your dog ends up with a depleted gut biome.

Normally, these beneficial bacteria help outcompete problematic bacteria, but when the beneficial bacteria die off, they provide an opening for the harmful varieties.

If these bad bacteria set up shop in your canine’s intestinal tract and start reproducing, vomiting, diarrhea and other digestive problems will often follow.

However, by providing probiotic supplements to your dog, you can usually restore the gut flora to its original state. This will typically help alleviate intestinal symptoms and make your dog feel better.

Wait, Aren’t Bacteria Bad?

The world is home to an astonishing number of bacteria – they pretty much cover every inhabitable surface of the planet. Scientists aren’t sure exactly how many different species exist, but estimates range from 10,000 to over 1 million.

As you’d expect, there is considerable diversity among this group. Different species live in different environments, subsist on different resources and go about life in different ways.

Many are completely benign and ubiquitous, while others are rare and exceedingly dangerous. Some are actually vital to other species.

The point being, while some bacteria are “bad,” others are quite important and can be generally considered to be “good” bacteria.

Probiotics are comprised of one or more species belonging to the latter category.

What About Prebiotics for Dogs?

Several probiotic supplements also contain prebiotics, which are also helpful for restoring proper digestive function. Prebiotics are not bacteria; instead, they are food sources for beneficial bacteria.

They are often included in supplements to help support the probiotic bacteria being delivered, to ensure that the bacteria do not starve once inside your dog’s intestines.

Additionally, because it is likely that some beneficial bacteria are already present inside your dog’s digestive tract, prebiotics can help support these populations too.

Prebiotics are typically fibrous substances that your dog’s body cannot digest. This ensures that they will survive passage through the stomach to reach the small intestine.

Inulin – a type of polysaccharide produced by many plants – is one of the most commonly used prebiotics for dogs. It is typically harvested from chicory root.

Different Probiotic Strains for Dogs

As referenced earlier, the world is full of different bacterial species (or strains, as they are often called), and each interacts with its environment in different ways.

And this holds true for those in your dog’s digestive tract too – there are likely dozens of different beneficial bacteria that help to keep him healthy.

Some of these strains are undoubtedly more helpful than others in restoring proper digestive function, but the scientific data on the subject is not conclusive.

Although there is some data demonstrating the efficacy of a few strains, such as Bifidobacterium animalis and Enterococcus faecium, the efficacy of others remains unknown.

Given this uncertainty, some of the best probiotics for dogs include several different bacterial strains to help achieve the best possible results.

However, some studies have demonstrated that different bacterial strains can actually work against each other, so much more research is necessary.

Buying Guide: How Can You Select the Best Dog Probiotic?

Now that you understand the role beneficial bacteria play in your dog’s health, you’ll want to compare the various products available so you can select the best probiotic for your dog.

Although it is impossible to guarantee that a given product will alleviate your dog’s symptoms, you can increase your odds of success by considering the following recommendations.

1. Opt for canine probiotics with the best reviews from other dog owners

Because scientific data regarding the efficacy of various probiotics is somewhat limited, one of the best ways to find the best probiotics for dogs is by reading the reviews of other dog owners.

Chances are, the better the reviews of a given probiotic are, the more likely it will help your dog feel better.

2. Look for dog probiotics made in the USA, Canada or Western Europe

Unfortunately, some supplements may be contaminated during the manufacturing process or include ingredients not listed on the label.

To avoid this as much as possible, stick with supplements made in countries and regions with strict safety- and quality-control standards.

3. Try to select a dog probiotic formulated with natural flavors

If your dog won’t eat a probiotic, it won’t do him any good, so you should always look for probiotics that feature dog-friendly flavors, such as beef or chicken.

This is especially important for tablets or chews, as you’ll want your dog to accept them like a treat.

4. Seek out probiotics that are designed to survive the journey into your pet’s digestive tract

Your dog’s digestive tract is a harsh environment that is designed to kill most bacteria that enter it, including those in many probiotics.

To help prevent this from happening, the best manufacturers encapsulate the bacteria in a type of shell that protects it from stomach acids and digestive enzymes.

5. Avoid products that do not indicate an expiration date or guaranteed live bacteria analysis

The bacteria in a probiotic supplement cannot live forever, and all probiotics will eventually contain nothing but dead bacterial cultures, if not used by a given date.

Most of the best probiotics for dogs will provide information on the label that indicates the length of time that the cultures will remain alive as well as an expiration date.

6. Try to select dog probiotics that also contain prebiotics

It is not only important to ensure the beneficial bacteria in a probiotic survives its passage through the stomach, you also want to make sure that the bacteria have the best chance of thriving once in the small intestine.

One good way to do this is by providing them with prebiotics – food – to help them grow and reproduce.
