As pet parents, we’re always looking for ways to improve our dogs’ health and happiness. One of the growing trends in pet care is the use of probiotics for dogs. These tiny, beneficial microorganisms are known for promoting gut health, but their benefits go far beyond digestion. 

Two veterinarians are checking a dog's health and talking about probitiocs.

Probiotics are becoming a popular supplement in the world of dog health. These supplements help keep your dog’s skin healthy and its immune system strong. Think of canine probiotics as little helpers that keep your dog’s tummy happy.

In this blog, we’ll learn more about probiotics and why they’re good for dogs. 

What Are Probiotics for Dogs?

Your dog’s gut is home to billions of microorganisms.

When everything is in balance, it works like a well-oiled machine. However, stress, illness, medications, or even a poor diet can throw off this balance. This leads to issues like diarrhea, gas, and a weakened immune system. This is where probiotics for dogs come in.

Probiotics for dogs are generally live bacteria or yeast that offer a ton of benefits.

What Are the Benefits of Probiotics for Dogs?

These supplements have a lot of advantages that can improve your dog’s overall health and life. Here’s why probiotics are good for dogs:

Improved Digestion

Probiotics for dogs can help with common issues like chronic diarrhea, constipation, bloating, and gas. They help dogs break down food and absorb nutrients, making the most out of your dog’s meals.

Strengthened Immune System

Around 70% of the immune system is located in the gut, so by enhancing gut health through probiotics, your dog's defenses are stronger. This improves pathogen defense and antibody production. In short, fewer diseases. 

Relief from Allergies

For dogs with skin allergies, probiotics can be a big help. They reduce the associated inflammation and lower histamine levels, providing a better chance at comfort. 

Better Skin and Coat Health

Probiotics can help keep the skin and coat healthy, reducing irritation, dryness, excessive shedding, and skin issues. They also keep a stronger skin barrier and improved nutrient absorption, furthering a healthy skin and coat. 

Reduced Stress and Improved Behavior

Gut health and mental health are connected through the gut-brain axis. Essentially, this means that your dog’s behavior will significantly improve through probiotics. These can help reduce stress and assist with anxiety-related behaviors.  

Improved Overall Health

All in all, the benefits all point toward a much better overall health for dogs. When their gut is healthy, they are happier and have a better outlook during their everyday routines. Plus, they experience fewer health issues.

Should a Dog Have Probiotics?

It will depend. If your dog is generally healthy, then they will be fine with their normal diet and exercise routines. Dogs should have probiotics when they need additional support for their gut, which is usually when they’re having a health or nutritional problem. 

What Are the Types of Probiotics for Dogs?

Not all probiotics are the same, and different strains of bacteria provide different benefits. So, before you choose the right one for your dog, here's an overview of the common ones: 

  • Lactobacillus acidophilus. This is one of the most well-known probiotic strains and is great for overall digestive health. This probiotic improves immune function and prevents the growth of unwanted bacteria. It’s also beneficial for reducing diarrhea.

  • Bifidobacterium animalis. A highly effective probiotic strain used to help improve stool quality, assist with constipation, and improve digestion. It’s a core component in high-quality probiotics for dogs. 

  • Enterococcus faecium. Just like the previous probiotic strains, Enterococcus faecium can help restore a good balance of bacteria in your dog’s stomach. It’s particularly helpful for dogs that have stomach aches during stress or medication. 

  • Bacillus coagulans. This type is mostly used for digestive support, reducing gas and bloating in dogs. It also works great in stool consistency, immune function, and managing inflammatory digestive diseases. 

  • Saccharomyces boulardii.This is an excellent probiotic yeast for managing diarrhea and inflammation, as well as helping with stool quality. It’s a good option if your dog has any chronic gut issues.

Sources of Probiotics for Dogs

There are several ways to give your dog the probiotics they need. The important thing is to make sure this probiotic is safe, so we recommend bringing your best friend over to the clinic first. In the meantime, here are the common ones: 

Probiotic Supplements

The most widely used option of probiotics for dogs is a supplement type that is specifically designed for our pups. High-quality supplements often contain specific probiotic strains tailored for dogs. These are:

  • Powders

  • Chews

  • Capsules

Probiotic-Enriched Dog Foods

Some dog food brands now include probiotics in their recipes. These specially formulated foods are designed to support your dog’s gut health as part of their daily diet. Be sure to look for options that list live and active cultures on the label.

Natural Sources of Probiotics

Certain human foods are naturally rich in probiotics and can be shared with your dog in strict moderation. 

  • Plain, unsweetened yogurt. A good source of live culture, but make sure it’s free from artificial sweeteners.

  • Kefir. Similar to yogurt but higher in probiotics, kefir is a fermented milk drink that’s safe for most dogs in small amounts.

  • Fermented vegetables. This includes fermented carrots, cabbage, and green beans. 

What Are the Side Effects of Probiotics for Dogs?

A veterinarian is talking to a pet owner about the side effects of probiotics for dogs. The owner is carrying his white dog in his arms.

They are usually safe for dogs, beneficial even. But even then, there are some possible side effects to consider. These include:

  • Digestive upset

  • Diarrhea

  • Bloating

  • Constipation

When introducing probiotics to dogs, some may experience mild side effects as the gut adjusts. Generally, these symptoms are short-lived and should resolve. Plus, some probiotics can have additional flavorings and additives, which can be bad for dogs, so always choose the safest ones.

What to Know Before Giving Your Dog Probiotics

If you want to start giving your dog probiotics, here are some key things to consider first: 

  1. Not All Probiotics Are the Same

Some types of probiotics focus on general health, while others focus specifically on digestive health. Others are also made to support specific needs, such as diarrhea or skin health. Visit our vet pharmacy so we can help you decide the most suitable one. 

  1. Stick to Dog-Specific Products

Human-grade supplements are often not ideal for dogs because they have a different gut microbiome. Plus, some contain additives that aren't good for dogs. Always stick to what's right for them. 

  1. Check for Side Effects

Although probiotics are generally safe, some dogs can experience potential side effects such as gas, bloating, or soft stools. These symptoms usually resolve quickly. If not, talk to us immediately.

  1. Store Properly

Probiotics are living microorganisms, and their effectiveness depends on proper storage. This means you should always keep them in a place that is cool and dry. 

  1. Probiotics Are Not Always Necessary

Even if they're beneficial, they aren't crucial. Always check with us first to see if your dog really needs probiotics or not. It's going to depend on their digestive and overall health.

  1. Consult the Vets

Before starting your dog on probiotics, let our vets do a wellness check. We can recommend the best strains, dosage, and product for your dog’s unique needs.

Final Thoughts

Probiotics for dogs are a simple yet super powerful way to support your best friend’s overall health. These supplements improve your dog’s digestion, strengthen its immunity, and promote a shiner coat. The benefits are pretty endless.
