You’ve picked out the best dog food to support his nutritional needs, whether it’s a low protein dog food, a dog food for sensitive stomachs, or an organic dog food, and you’ve also picked out the best dog bowl so that he can thoroughly enjoy your meal. But if you really want to step up your pet’s health or if your pooch is exhibiting digestive health issues, than you might want to consider adding a probiotic to his diet.

If you’ve never used probiotics for dogs, you might be wondering exactly what probiotics are, how they can benefit your pup, and what features the best probiotics for dogs offer. Below, we provide valuable information about dog probiotics so that you can make the best choice for the health of your furry best friend.

What are Dog Probiotics?

Basically, probiotics are made up of live bacteria that improve the health of your pup; specifically the health of his digestive system. While you might think of bacteria as being bad for your dog, there are actually good bacteria that offer numerous health benefits.

Probiotics have been proven to be an effective way to improve the digestive health of dogs, especially those that are suffering from issues with their gastrointestinal system. For example, if your pup suffers from diarrhea or flatulence, probiotics can help to ease his symptoms. But that’s not all probiotics do. They can also help to strengthen your pup’s immune system, ease allergies, and just improve his overall health and well being.

What are the Benefits of Probiotics for Dogs?

It’s long been known that probiotics are beneficial for humans, but researchers are now finding that they are just as beneficial for canines. Some of the benefits that your pup can expect to gain from probiotics include:

  • Improved gastrointestinal health. Probiotics can help to reduce the frequency and duration of symptoms that affect the gastrointestinal tract, such as diarrhea, constipation, and flatulence.
  • Improved digestion. The healthy flora that probiotics offer can help your dog get more out of the premium quality food that you are feeding him, as he will be able to absorb nutrients better.
  • Stronger skin and coat. Probiotics can also help to improve your pup’s skin and coat, especially if he suffers from allergies.
  • Strengthened immune system. It has also been found that probiotics can help to strengthen a dog’s immune system, thus improving his ability to fight off infections.

In other words, probiotics for dogs can significantly improve the overall health and well being of your canine companion.

Things to Look for

When it comes to the health and well being of your dog, choosing the best probiotic is absolutely essential. Unfortunately, there are a lot of products on the market that advertise they offer the best supplements, but in reality, they either do very little or worse, they can cause adverse effects.

If you want to ensure that you are providing your pup with the best probiotics for dogs, here’s a look at some features that you should be looking for:

  • High quality bacteria. The best dog probiotics will be formulated with the highest quality bacteria. There are a number of different high quality bacteria, but some include:
    • Bacillus coagulans, which coat the lining of the digestive tract in order to protect your pet from harmful bacteria that can make their way into his system.
    • Bifidobacterium animalis, a naturally occurring bacterium that is found in the large intestine of a dog. This probiotic helps to improve your pup’s digestion and it also improve the functioning of his immune system.
    • Bifidobacerium bifidum, another bacterium that can strengthen your pet’s immune system. It also helps to balance out the bacteria inside your pup’s stomach, ensuring that there is a healthy balance.
    • Enterococcus faecium, which is another naturally occurring bacterium, and it’s found in the stomach of your dog. This probiotic aids in digestion and also ensures there is a good balance of bacteria in his stomach.
    • Lactobacillus plantarum, which helps to improve unpleasant gastrointestinal symptoms, such as diarrhea.
  • Easy application. It can be difficult to give some dogs probiotics; especially those that are very particular about their food. To ensure that your pup is ingesting the probiotics you are giving him, choose one that offers an easy application. A powder or a capsule that is served in a capsule and can be opened up is ideal, as you can disguise the probiotic in his food.
  • A healthy amount of probiotics per serving. While there is no right or wrong amount of probiotics per serving that your dog should be receiving, to see optimal results, look for a product that offers somewhere between 2 and 6 billion per serving size.
  • The amount of species. The more species of bacteria that are present in the probiotic, the more health benefits it is going to offer your dog.

Summing It Up

Whether your pet is suffering from digestive health issues or you simply want to improve his overall health and well being, than adding a high quality dog probitoc to his diet is a wise option to consider. It has been determined that the best probiotics for dogs can offer numerous benefits, including improved digestive health, a stronger immune system, allergy relief, and even healthier skin and coat. If you want to improve your pup’s health, choose a high-quality probotic, like one of the options recommended in our review.
