Antibiotics are medicines used to treat and prevent infections caused by bacteria. They won't treat illnesses caused by other bugs like viruses. Antibiotics can be life-saving drugs, but many harmful bacteria are becoming resistant to them.

Every year, antibiotics help millions of dogs to recover from infections. But they only work against bacteria. And not all bacteria are harmful. Side effects of treatment are common, especially tummy upsets and allergies. If we use antibiotics properly and only when we need them, they’re more likely to work when your dog needs them most.
