Probiotic FAQ’s

1. Is it OK to give dogs probiotics every day?

Dogs can take probiotics on a regular basis to promote everyday digestive health and well-being.

2. How do you know if your dog needs probiotics?

The majority of dogs require probiotic and enzyme supplements.

3. Can I feed my dog human probiotics?

Human probiotic supplements won't cause any harm, but they won't deliver all the species-specific benefits you're looking for when you supplement their diet. Instead, you need a probiotic for dogs — in other words, a probiotic that contains ingredients that have been clinically tested in dogs

4. Do vets recommend probiotics for dogs?

Canine probiotics are widely used to decrease gas and diarrhea. They are also often recommended for dogs with various digestive diseases. And just like with people, veterinarians often recommend probiotics for dogs following antibiotic treatment. This helps replace the good bacteria in the digestive tract

5. Is pumpkin a probiotic for dogs?

Pumpkin can act as a prebiotic that feeds the friendly bacteria in your dog's gut, which helps with everything from colon function to the immune system. Pumpkin's blend of soluble and insoluble fiber can be an effective remedy for both diarrhea and constipation.

6. How long should a dog be on probiotics?

I recommend following the instructions on your dog’s probiotic supplement for at least a month or two to determine what the maximal benefits might be. Then play around a bit to see if you can get away with giving it every other day or just a couple of times a week.

7. Do probiotics help itchy dogs?

In pets with pyoderma, bacteria on the skin triggers the immune system to react by creating an itchy, inflamed, bumpy skin rash. Probiotics for itchy dogs applied topically can help prevent the itchy skin rash from forming by blocking skin cells from recognizing the bad bacteria

8. What are the side effects of probiotics in dogs?

Some dogs may experience digestive discomfort, diarrhea, bloating, gas, constipation, or nausea when starting probiotics. A digestive symptom may temporarily get worse before it improves. Changes in appetite may be an early indicator of an adverse reaction

9. What time of day should I give my dog probiotics?

In the morning your dog’s digestive system will offer the least amount of resistance to getting the good stuff to his gut to strengthen it and boost nutrient absorption and ensure a healthy immune system.

10. Do probiotics help firm up stool in dogs?

Yes! Supplementing your dog with “helpful good” bacteria can help improve his/her digestion and definitely firm up an unpleasant soft stool. Probiotics for dogs like can also help with your dog's allergies, yeast infections, dermatitis, and even dental issues.
