Frequently Asked Questions About Giving Your Dog Probiotics to Support Allergy Relief

  1. Q: What are probiotics and how can they benefit dogs with allergies? A: Probiotics are beneficial bacteria that help maintain the health of the digestive system. In dogs with allergies, they can help regulate the immune system, reduce inflammation, and potentially decrease allergic reactions. Probiotics may also enhance the gut barrier function, further reducing allergic symptoms.
  2. Q: Are all probiotics the same? A: No, not all probiotics are the same. Different strains of probiotics can have different effects, and some strains may be more beneficial for certain health conditions than others. It’s crucial to choose a probiotic supplement specifically designed for dogs and one that’s clinically proven to help with allergies.
  3. Q: How long does it take for probiotics to work? A: The effects of probiotics can vary depending on the individual dog and the severity of their allergies. Some dogs may show improvement in a few days, while others might take several weeks to a few months to show noticeable benefits.
  4. Q: Can I give my dog probiotics meant for humans? A: While it’s not generally harmful to give dogs human probiotics, it’s more beneficial to give them probiotics specifically formulated for their species. This is because the bacterial strains beneficial to human gut health might differ from those beneficial to canine gut health.
  5. Q: Can probiotics cause side effects in dogs? A: Most dogs tolerate probiotics well, but some dogs might experience minor side effects like gas, bloating, or changes in stool consistency when they first start taking them. These effects usually subside once the dog’s system adjusts to the new bacteria.
  6. Q: Do I need a prescription to give my dog probiotics? A: No, you do not typically need a prescription for canine probiotics, as they are usually available as over-the-counter supplements. However, it’s always wise to consult with a veterinarian before starting any new supplement regimen.
  7. Q: What if my dog doesn’t like taking the probiotic? A: Probiotics for dogs come in various forms, including powders, capsules, chews, and even added into some dog foods. If your dog doesn’t like one form, you can try another. Some can be mixed into their regular food unnoticed.
  8. Q: Can I give my dog probiotics while they are on antibiotics? A: Yes, it’s often beneficial to give dogs probiotics during and after antibiotic treatment because antibiotics can disrupt the balance of bacteria in the gut. However, you should administer them a few hours apart to ensure the antibiotic doesn’t kill the probiotic bacteria.
  9. Q: Can probiotics cure my dog’s allergies? A: Probiotics can help manage and alleviate some of the symptoms of allergies in dogs, but they are not a cure. Allergies are usually managed rather than completely cured. It’s important to work with your vet to create a comprehensive allergy management plan.
  10. Q: How long will my dog need to take probiotics? A: This largely depends on your dog’s individual health condition and response to the supplement. Some dogs may benefit from short-term use, while others may require a long-term approach. It’s essential to consult with your vet to determine the best plan for your dog.


What Clinical Studies Have Been Done on The Benefits of Probiotics for Dogs with Allergies?

  1. A 2019 study published in “Frontiers in Veterinary Science” examined the effects of probiotics on dogs with atopic dermatitis, a type of allergic skin disease. The study found that dogs given a multi-strain probiotic experienced a significant reduction in skin lesions compared to a control group. This suggests that probiotics may be beneficial in managing this common canine skin allergy.
  2. Another study conducted by researchers in Finland and published in “Veterinary Record” in 2016 showed that puppies given probiotics early in life were less likely to develop atopic dermatitis than those that did not receive probiotics. This indicates that early introduction of probiotics could potentially have a protective effect against certain allergies.
  3. A research article published in “BMC Veterinary Research” in 2018 indicated that probiotics could enhance the efficacy of immunotherapy in dogs with allergies. The study found that dogs with atopic dermatitis receiving allergen-specific immunotherapy, coupled with a certain probiotic, had better clinical improvement compared to dogs only receiving immunotherapy.

These studies suggest that probiotics could potentially have a role in preventing and managing allergies in dogs. However, more research is needed to fully understand the complexities of this relationship and to determine which specific strains and dosages of probiotics are most beneficial.

Please consult your veterinarian before starting any new supplements in your dog’s diet, as every dog is unique, and what works for one may not work for another. It’s also crucial to note that probiotics should not replace any current allergy treatments or medications your pet may be on, but they can be considered a complementary approach to overall wellness.
