Probiotic Chews for Dogs Buying Guide

Having a healthy diet with plenty of regular exercise is an obvious requirement to ensure your tail-wagger remains in tip-top condition. Yet many pups can lack the required vitamins and minerals to digest their food and keep a strong immune system — all because of a lack of friendly gut bacteria. 

A variety of circumstances can cause an imbalance, such as a prescribed course of antibiotics or even stress. Probiotic chews for dogs could be the solution.

Does My Dog Need Probiotics?

Your dog may benefit from the inclusion of a probiotic in their diet, whether they’re puppies or seniors. This is due to their body being more susceptible to the imbalances caused in their body. 

For many pets with long-standing health issues, from allergies to infections, their immune systems can be weakened. This can leave their microbiomes less than desired.

How To Choose the Best Probiotic Chews for Dogs

Let’s take a closer look at what to look out for and how to pick the best probiotic chewables for dogs.

Other Health-Improving Ingredients

While probiotics offer amazing benefits, when combined with other ingredients, like prebiotics, they work in unison together. This means you’ll stand a better chance of seeing the results you want from your chews. 

Plus, some probiotics include other health-boosting nutrients — vitamins, minerals, etc., — for all-encompassing well-being support.

Bacterial Strains

The best dog probiotic chews will disclose the strains and ingredients to show the benefits they can provide your dog. 

You can only have these benefits from your probiotic if these strains work alongside hundreds of other species. The more strains of bacteria found in a product, the more benefits your furry friend will be able to gain from it. So look for multi-strains for an all-around boost.

Individual Needs

You should also consider the root cause behind the reasons for needing to give your furry friend a probiotics chew. They may require further treatment that a probiotic would not be able to treat. So, make sure you consult your vet beforehand.

The Benefits of Probiotics

Here are a few ways your dog can benefit from a probiotic.

Promotes Digestive Health

As we’ve mentioned, including the much-needed healthy bacteria in your dog’s gut can vastly improve all aspects of their gastrointestinal health — from gassiness and bloating to less sickness and diarrhea.

Supports Immune System Function

Many pet parents don’t realize antibiotics and other prescription medicines can cause damage to their pet’s immune system. These meds can deplete the required healthy levels of good bacteria needed within their gut to promote healthy bodily function. 

A probiotic can help to maintain proper gut flora and restore better health to your pup.

Discourages Growth of Harmful Bacteria

When healthy bacteria in your dog’s gut are reduced, this can lead to perfect conditions for harmful bacteria. If this imbalance is prolonged, it can lead to worsening health conditions and an unhappy or poorly pet. Supplementing with probiotics levels things out and prevents this from occurring. 

Enhances Nutritional Absorption

With sufficient levels of probiotics, your bow-wow can absorb vitamins and minerals much more efficiently. As a result, you have a happier and healthier hound — and could even increase their life expectancy.
