Frequently Asked Questions

Can I give my dog probiotics while on antibiotics?

Yes — but the type matters. Bacterial probiotics (like FortiFlora or Petz Park) are killed by antibiotics. You need a yeast-based probiotic like Saccharomyces boulardii (Hero's formula) which is antibiotic-resistant. Give it 2 hours apart from the antibiotic dose.

What's a good CFU count for a dog probiotic?

For meaningful gut support, aim for at least 1 Billion CFU. Most budget options sit around 60–100 million CFU which is often insufficient for dogs with gut issues. Hero's 10 Billion CFU is the highest available in Australia.

How long should I give my dog a probiotic?

For acute gut upset (diarrhoea, vomiting), 1–2 weeks is usually sufficient. For chronic gut issues or dogs on regular antibiotics, daily long-term use is recommended. Always consult your vet for ongoing health conditions.
