Benefits of Probiotics for Dogs

What do probiotics do for dogs? The answer is – Exactly what probiotics do for humans.

Like us, dogs also have a gut system filled with bacteria that can profoundly influence their overall health. Probiotics help maintain an appropriate balance of good bacteria in your pet’s gut.

Check below the benefits of probiotics for dogs:

  • Alleviate bloating and digestive issues caused by illness or stress. Illness and stress in dogs disrupt the balance between healthy and unhealthy microbes in their gut. This leads to conditions like dog diarrhea, gas, bad breath and cramping. Studies show that probiotics for dogs can reduce the duration of diarrhea from seven to four days.
  • Decrease negative effects of antibiotics. While antibodies fight infection, they may negatively affect your dog’s gastrointestinal health. So, start giving them probiotics a few days in advance to curb the side effects of antibodies.
  • Reduce allergies. Allergies are responses to the improper immune system and imbalanced gut bacteria. Best probiotics for dogs may lessen allergy symptoms.
  • Promotes good behavior. Bad gut means a fussy and annoyed dog, and a healthy gut means a happy and healthy pet. So, as mentioned above, probiotics promote good gut health, making your furry companion feel comfortable, happy and healthy.
  • Healthier teeth, breath and coat. Giving a daily recommended dosage of probiotics will make your dog healthy from the inside. Better internal health means a healthy body outside.

What to look for when buying probiotics for dogs?

You must probably be wondering how probiotics are beneficial for dogs. The healthy bacteria are known as probiotics and help your dog’s digestive tract, itchy skin, stress, allergies, and much more. So, let’s narrow down a few considerations when buying probiotics for dogs.

Multiple Strains of Probiotics are Beneficial: Having probiotics with multiple strains of healthy bacteria benefits the overall body of your paw-some friend. Each bacteria has unique properties which target various issues of gut health and other systems. So, check the ingredient panel, which has bacteria like:

  • Enterococcus faecium
  • Lactobacillus acidophilus
  • Lactobacillus casei
  • Lactobacillus plantarum
  • Bifidobacterium bifidum
  • Bifidobacterium animalis
  • VSL#3

 

Check Flavors: Generally, probiotics are not delicious enough for furry friends. Therefore, the probiotics manufacturers add flavors, like a fruity or chicken flavor, adding taste to your dog’s diet. However, you must check the ingredients and choose the non-vegetarian flavors your dog loves.

Having an unidentified protein and a mix of flavors is not good. A single taste with multiple bacterial strains is a good choice.

Choose Probiotics Which Also Contains Prebiotics: You must know that probiotics work when they have a good food source. It can be in the form of beans, peas, chicory root, Jerusalem artichoke, etc.

But, if your furry friend refuses to have them, you must look for probiotics having prebiotics. The probiotics will feed on prebiotics and elevate your dog’s health—for example, the presence of inulin in probiotics.

Consider the Form of Probiotics: Probiotics are available in various forms, which include capsules, powders, dog food, soft chewable, etc. Depending on the nature of your pet, choose the right form.

For example, the powder is easily dissolvable in food, and dogs also easily intake soft chews. Capsules can be tough, but it depends on the individual nature. So, choosing the right form will help you make the best out of it.

Always Check the Colony Forming Units (CFU): The lining of the dog’s gut is highly acidic, and many probiotics don’t survive it. So, always check for the colony forming units (CFU) while selecting the probiotic. It should be at least 3 billion CFU. This will help you choose the most effective probiotic for your furry friend.
