Updated September 2, 2022

As a loving pet owner, you want your dog to live a long and healthy life. And a big part of that is making sure they're getting the right nutrients in their diet. But with all the different types of food and supplements out there, it can be difficult to know what's best for your dog.

One area that's often overlooked is gut health. Just as in humans, a healthy gut is crucial for a dog's overall health. That's why prebiotics, probiotics, and digestive enzymes are so important.

Keep reading to discover everything you need to know about these powerful gut-health boosters and how to incorporate them into your dog's diet.

What Are Prebiotics for Dogs?

Prebiotics are a type of dietary fibre that acts as fuel for probiotics (good bacteria) in the gut. By feeding the good bacteria, prebiotics help promote a healthy balance of gut flora. This is important for many reasons, including supporting immunity, preventing inflammation, and aiding digestion.

In order to be effective, prebiotics must be resistant to the digestive process so that they can make it to the large intestine intact. There, they are fermented by gut bacteria and turned into short-chain fatty acids (SCFAs), which are a source of energy for cells in the colon.

A common food source of prebiotics is chicory. Learn about the benefits of Chicory for Dogs and why it's a great ingredient to see in your dog's food

SCFAs play other important roles, such as reducing inflammation, supporting a healthy immune system, and maintaining the integrity of the gut barrier. They may also help prevent diseases like obesity, diabetes, and cancer.

Many raw dog foods include prebiotics to ensure optimal digestion and absorption of nutrients. Here are a few dog foods that offer superior digestibility from prebiotics:


What Are Probiotics for Dogs?

Probiotics are live microorganisms (bacteria and yeasts) that are beneficial for gut health. They're similar to the good bacteria that naturally live in the digestive system and can help restore the balance of gut flora when it's been disrupted. That's why probiotics are often referred to as "friendly," "good," or "healthy" bacteria.

Probiotics work together with the good bacteria that reside in your dog's gut to keep harmful bacteria in check. They also help break down food and absorb nutrients, support immunity and contribute to a healthy digestive system.

The relationship between prebiotics and probiotics is symbiotic, meaning they work together to support gut health. Prebiotics act as food for probiotics, while probiotics help prebiotics achieve their full potential in the gut.

Probiotics are a helpful part of a complete dog diet, and tasty meal toppers like Goat's Milk for Dogs can ensure appropriate probiotic inclusion. 


What Are Digestive Enzymes?

Digestive enzymes are proteins that help break down food into nutrients so that the body can absorb them. Dogs produce their own digestive enzymes, but the amount and activity of these enzymes can decline with age. This is one reason why senior dogs often have trouble digesting food properly.

Senior dog foods are often formulated with easier-to-digest proteins and other digestion-friendly ingredients to ensure that older dogs are getting the nutrients they need to fight the effects of ageing. 

Dogs produce three main types of digestive enzymes: proteases, which break down proteins; amylases, which break down carbohydrates; and lipases, which break down fats. Cellulase is another type of enzyme that helps break down fibre, but dogs don't produce this naturally.

The pancreas is the primary organ responsible for producing digestive enzymes. These enzymes are then secreted into the small intestine, where they help break down food.

If the pancreas isn't functioning properly, or if not enough enzymes are being produced, dogs can experience poor digestion, nutrient deficiencies, and other health problems.

Dietary sources of digestive enzymes can be found in many foods, like pineapple and mango. Find out which of your dog's favourite fruits and vegetables might be offering more nutrition than you thought.

Do Dogs Need Prebiotics, Probiotics, and Digestive Enzymes?

Now you know what prebiotics, probiotics, and digestive enzymes are, let's take a look at why you may want to add them to your dog's diet. As mentioned earlier, gut health is crucial for dogs (and humans!) of all ages. A healthy gut supports immunity, digestion, nutrient absorption, and more.
