Living With It
Care, Cost and Maintenance
Introduce Slowly
Start with half the recommended dose for 3-5 days to allow your pet's digestive system to adjust.
Mix with Food
Most powders and toppers should be mixed into wet or dry food for best palatability and absorption.
Monitor Stool Quality
Track your pet's stool consistency daily. Adjust dosage if needed, and consult your vet if issues persist.
Pro tip
Our top tip: rotate between a probiotic powder and a pumpkin topper weekly to maintain diverse gut flora and prevent reliance on a single supplement.
Frequently asked questions
Are organic supplements better for sensitive stomachs?
Organic supplements avoid synthetic additives and pesticides that can further irritate a sensitive stomach. We recommend them as a safer first choice.
How quickly will I see results?
Many owners report firmer stools within 3-7 days. Probiotics may take up to 2 weeks for full effect. Individual results vary.
Can I give both a probiotic and pumpkin topper?
Yes, they work well together. Pumpkin provides soluble fiber (prebiotic) that feeds the probiotics, enhancing their effectiveness.
Are these supplements safe for puppies or kittens?
Most are safe for pets over 8 weeks old, but always check the label and consult your veterinarian for young animals.
Should I refrigerate probiotics?
Some probiotics require refrigeration, but many are shelf-stable. Follow the storage instructions on the product label.
