10 Best Probiotics for Dogs

Probiotics are tiny bacteria that live in the intestines and help keep them healthy. They also positively impact other body parts, including the brain, the immune system, and the skin.

When you give your dog probiotics, you’re giving them good bacteria that make their digestion process more manageable and their immune system robust.

Keep reading to learn more about why dogs need probiotics and how to choose the best probiotics for dogs to improve your furry friend’s health and quality of life.

Benefits Of Probiotics In Dog’s Health

Here’s how the probiotics will impact your dog’s health positively :

1. Make Digestion Work Better

Probiotics help your dogs to digest food properly by supplementing the right bacteria in their stomach. They can help with constipation, diarrhea, gas, and bloating. Probiotics also help reduce the risk of indigestion and other stomach issues.

2. Help With Allergies

The good bacteria in probiotics can help balance out some harmful bacteria, improving overall health and reducing the severity of allergies. For example, probiotics are known to positively affect gastrointestinal (GI) issues such as diarrhea and irritable bowel syndrome, which are common symptoms associated with canine allergies.

3. Boost Immune System During Pregnancy

Probiotics are vital for pregnant dogs because fluctuating hormones and increased blood volume weaken their immune systems. If you’re in the process of getting your dog pregnant, now is an ideal time to start supplementing with probiotics. It will help boost its digestive health and immune system function, ensuring it delivers healthy puppies.

4. Help Them Heal From Surgery Or Illness Quickly

Probiotics are great for helping your dog recover from illness, surgery, or other procedures. They can help with the healing process by boosting the immune system, digestive system, and skin health. They can also improve hair quality by promoting healthy skin cells that help prevent shedding.

5. Build Their Immunity

Dogs are just as susceptible to illness from bacteria as humans. They can suffer even more severe effects if there is an imbalance of good and bad bacteria in their gut due to their generally less varied diet and negative response to many standard vaccinations.

That’s why it’s crucial to give your dog a probiotic. It boosts the immune system by providing a line of defense against harmful bacteria and viruses.

When To Give Probiotics To Dogs

Probiotics are necessary for dogs that often experience bloating, gas, constipation, diarrhea, or a decreased appetite. It’s also essential to give them probiotics during stressful periods. Chat with your vet before feeding probiotics to your dog. The vet will look at your pet’s medical history, then suggest the best probiotic.

All probiotic supplements aim to promote the development of beneficial bacteria in your dog’s body. However, they’re not all similar. Giving your dog the probiotic that your vet recommends would be best.

Usually, the recommended product contains bacteria primarily found in the canine intestine, such as:

  • Lactobacillus acidophilus: They keep good bacteria in balance and ward off disease-causing germs.
  • Enterococcus faecium: They benefit dogs that have digestive problems.
  • Bifidobacterium breve and Bifidobacterium lactis: Help reduce diarrhea
  • Lactobacillus casei: This bacteria influences your dog’s emotions and moods.

Should You Accompany Probiotics With Prebiotics?

Prebiotics are soluble, indigestible fiber that probiotics require to develop. They feed and help the probiotics to stay alive. That means probiotics can be less productive and may eventually go extinct without prebiotics. On the contrary, if the probiotics are well-fed, they will grow and support the production of new colonies of beneficial bacteria for your dog.

Types Of Dog Probiotics

There are different formulations of canine probiotics, including:

For each type of formulation, follow the instructions on the container and your veterinarian’s advice on the amount and how often to feed your dog.

Are Probiotics Drugs And How Safe Are They?

Probiotics don’t fit into either the food or medicine categories. They are regarded as natural supplements. In short, they are not subject to FDA regulation and are not necessarily required to adhere to stringent safety standards.

Nonetheless, remember that a product’s “natural” status does not guarantee its safety. Therefore, you must exercise vigilance when purchasing supplements for your dog.

If uncertain, discuss any potential probiotic use with your veterinarian. You could consult a veterinarian about probiotics through a telehealth service as well.

What To Consider When Buying Probiotics For Your Dog

Ensure that you check on these factors:

  1. Live Cultures – Many probiotic products contain dead cultures that don’t help digestion or boost immunity. Always pick a probiotic with live cultures.
  2. High-Quality Strains– If a product doesn’t list the strains used, it probably contains none. Probiotic packages may use an acronym to label the microorganisms they have.
  3. Consider the Bifidobacterium and Lactobacillus species, as most vets prescribe them for dogs’ gastrointestinal tracts. You can identify these species on the package as L or B for L.acidophilus and B.longum, respectively.
  4. Wet or Dry Probiotic – Liquid (wet) probiotics are often more palatable for dogs and can be a suitable alternative for dogs with individual medical requirements. On the other hand, dry probiotics may be cheaper and last longer. Whichever your choice is, ensure your dog will be okay with it.
  5. Colony Forming Units (CFUs) – The quantity of CFUs will determine the probiotic’s efficacy. Usually, more CFUs are preferable.
  6. Expiration Date – You’re purchasing a probiotic because it contains living microorganisms. Their shelf life is just a few months. So, check the expiry date, as the probiotic will lose its effectiveness after this date.
