What Is A Probiotic?

Just like in the human digestive system, A probiotic is a beneficial bacteria living inside your dog’s tummy. Literally, probiotics mean “life promoting”, they are there to balance the dog’s body as well as to balance the bad bacteria to keep things in order. A probiotics aids digestion helps boost the immune system, and extracts the vitamins and minerals from your dog’s food, and distribute them all over the body accordingly. They are also responsible for other health concerns like strengthening bones, reinforcing the immune system, and making teeth stronger.

When your dog has an unstable digestive system, you will notice they are experiencing some tummy issues such as belching, grumbling stomach even after mealtime, diarrhea, to name a few. These are signs that your dog might have an unhealthy digestive system. This is the reason why your dog will need the help of probiotics supplement to balance their bowel irregularity

No only Probiotic but also Prebiotic

Probiotics may not be enough to secure your dog’s healthy digestive system. And this is where prebiotics comes into play. A prebiotic is a form of fiber coming from food support the healthy growth of intestinal bacteria and they help also help balance the harmful bacteria just like probiotics’ purpose. When prebiotics are fermented in the large intestine, this will become a source of food of probiotics and this is where probiotics will take action and make the dog’s stomach are in good shape.

…And below are the benefits of prebiotic

We can say that prebiotics is tougher than probiotics the fact that they can reach the large intestine without any harm. From there, they will start to work their fermenting power for smooth digestion.

Boost the body to absorb more nutrients – From being fermented, prebiotics spreads to the stomach of your pets and aid the digestive system. Prebiotics break down each food and the more they are able to break down the food the more nutrients the dog is getting.

It Restores Intestinal Orders – Prebiotics are also responsible for restoring intestinal orders and your dog’s overall gut health. They help normalize the stomach issues and they correct all digestive issues for nutrients to be absorbed at maximum potential.

Compelling Reasons to Give Your Dog Probiotics

There are many reasons why you should give your dog probiotics and all of them are with good intentions. It is not enough to give him excellent kibble food, it is best to give him probiotics also. These are some of the reasons to help you convince that probiotics are perfectly safe and recommended for all dogs out there.

A Tendency to Strengthen Bones

There is an ongoing study about the correlation between prebiotics and bone density. A study revealed that prebiotics may help absorb calcium from a given diet and supplements. The study suggests that the more it absorb calcium, the more possibility of bone and density to increase.

Affects Dog’s Behavior

An unhealthy digestive system can also target emotional health. Your dog might not feel well and you are starting to notice that there is a behavioral change that can be alarming to them. These behavioral changes include obsessive compulsive actions like excessive licking. This is mainly due to gastrointestinal issues. With the support of probiotics, they might improve your dog’s behavior because of a well-functioning digestive system.

It Eases Your Dog’s Chronic Gastrointestinal Distress

Give your dog a premium quality probiotic with added nutrients and with prebiotics who suffer from chronic tummy issues. Giving this on a regular basis will help soothe the pain and will fight off the dab bacteria that causes your dog to have Chronic Gastrointestinal Distress.

You Senior Dog Will Thank You

Senior dogs are more prone to disease and chronic illnesses. Older dogs have weakened immune systems and one of them is their digestive system. So, with the help of giving your old dog probiotics, their digestive system will be strengthened and it can also become a key factor for your dog’s prolonged lifespan.

It Decreases the Side Effects of Anti Biotics

As much as antibiotics fight infections and bad bacteria, they can also kill good bacteria in their digestive system. When your dog takes antibiotics, there is a tendency that they will end up having diarrhea, stomach upset, bloating.

To help decrease the side effects of antibiotics, have your dog take quality probiotics ahead of your dog’s scheduled antibiotic for a week. Much better if it is symbiotic (combination prebiotics and probiotics) This is to strengthen the good bacteria in your pooch’s digestive system.

Helps Dogs with Constipation

There will always be a moment where your dog will be experiencing constipation. Dogs with constipation can become lethargic and may vomit at times. Dogs who are experiencing this must be given plenty of water, body conditioning (exercise), more importantly, give them probiotics. This will probably alleviate the dog’s constipation.

For Healthy Teeth

It is a proven fact that probiotics can even make dog’s teeth healthier. They slow the bacteria buildup of bad bacteria growing the dog’s teeth. If bad bacteria successfully build up, dogs might end up having a common periodontal disease like halitosis (unusual bad breath). Probiotics and even prebiotics are also good for dental care to dogs.

What to Choose When Buying the Best Probiotic for Dogs

When choosing the best product, you must be careful and knowledgeable to distinguish between substandard quality versus standards with the highest quality. There are thousands of probiotics products out there but only a handful of them has possessed the excellent caliber for maximum support of the dog’s digestive tract.

A few of those handful excellent products have made it to my list in which I have reviewed just to save your precious time. But first, I am going to breakdown some of the qualities of choosing the best probiotics for dogs.

Look for various bacterial strains listed in the ingredient

Usually, premium quality products have a lot to offer in their products, especially probiotics. Probiotics products for dogs must contain several beneficial bacteria. Each bacteria have a different function. The more it contains bacteria on the ingredient, the better for the dog’s overall health.

Determine the number of colony forming units (CFU) contains in the product

For the probiotic to become highly effective, there must be a sufficient number of colony forming units (CFU) contains in the probiotic supplement. The dog’s acidity level is high. Much better if there are at least 3 billion CFU. Some products offer less than this but do yourself a favor for your dog. Choose the recommended amount of CFUs so your dog’s health is in good shape.

Consider the format

Probiotics have various options to choose from, they are powdered and soft chews. Soft chews are great for dog treats because it is palatable and they think that it is normal food. While it seems palatable for them, once the package is open, there is a tendency where the probiotic’s potency may lose. Compared to powder that it is ideal because some of the products come with odorless and tastelessness.

Choose a product that has also prebiotics

It is because they are a great tandem for warding off bad bacteria and normalizing the digestive issue of the dog. Without prebiotics, the effectivity rate may not be as high when prebiotics is included. Prebiotics act as a booster for probiotics and for a better digestive system also. So, with the inclusion of prebiotic, guaranteed that the product is great for your dog.

When there is digestive enzyme in the label

The best way to ensure the probiotic product is one of the best is that there must include a digestive enzyme. This agent is also beneficial for the dog’s digestive system. They are the ones who do the balance for a better gastrointestinal tract. This is an actually ideal ingredient for dogs. Most often dog food lacks digestive enzymes. So, be sure that the digestive enzyme is also included for the dog to properly digest and absorb all the nutrients it needs.

Natural probiotic for my dog

If you are out on the budget, you can try some natural probiotic for your dog. It may not be highly effective than the probiotic food supplements above, but they can naturally work for your dog. There are plenty of them and you might even own some of them. Honey, leeks, banana, Jerusalem artichokes, and kefir. These can be your go to natural probiotic for your canine. For more suggestions, you are always welcome to discuss this matter to your veterinarian for a better nutritional diet plan for a better gut health of your adorable furry friend.

Frequently Asked Questions

Can I give probiotics for humans for my dogs?

Although there is no specific research or known studies regarding whether giving probiotics meant for humans is beneficial or not, it is a safe bet that you can. However, the efficacy rates of probiotics for humans and dogs are different.

However, it is recommended that you should administer probiotics that are suitable for dogs because they are designed for the dog’s digestive system and while probiotics for a human might become ineffective to your dog because there are some physiological differences to consider and dog’s acidity in the stomach is higher than humans. In short, yes but it is much more suitable if your give probiotics meant for dogs.

What are the side effects of probiotics for dogs?

As much as probiotics are helping the digestive system when regularly maintained, for starters, dogs might experience occasional side effects. These side effects include bloating, gas, diarrhea, and constipation. However, these are temporary because the dog is adjusting to food that is new to them especially if you change their diet plan with a probiotic supplement. The dog’s change in appetite is only a temporal issue before it improves for the long term depending on the usage of probiotic supplements.

Can My Puppy Take Probiotics?

Absolutely. It is much better if your puppy takes probiotics as early a possible. This will help your pup to develop their digestive system as they grow. It is better to keep them with enough probiotics during puppy days so their stomach will be flooded by good bacteria and they can build up there so by the time your puppy is matured, he is more immune and has a stronger digestive system. With regular intake of probiotics, your puppy has a low risk of gastrointestinal issues.

How Can I Include Them in my Dog’s Diet?

You must know the right supplement for your dog first and slowly introduce the supplement to your dog’s diet. If your dog loves to eat some of these, you can incorporate the probiotics supplement in the following food:

  • Oatmeal
  • Sweet Potatoes
  • Sliced Apples
  • Flaxseed meal

Final Thoughts

It is amazing how extremely helpful probiotics to dogs. Both holistic and traditional vets agreed to its useful function in the dog’s digestive system in the last decade. Back then, there was no knowledge about what it can do to dogs. But with years of studies and research, luckily enough, it is very helpful to a dog’s digestive system and it extended its benefits also to others else such as promoting good skin condition. With the proper nutritious diet plan and probiotics for dogs, you cannot simply ask for more. Even dogs will thank you that they are having the greatest care of their life.
