Dog ear infection treatment you can rely on

Claro® features three active ingredients that work together to give your dog relief. Florfenicol fights harmful bacteria, terbinafine fights certain strains of yeast, and mometasone furoate reduces swelling and associated discomfort and itching. If your vet thinks Claro® is right for your dog, just one dose treats the infection AND soothes painful symptoms.

Vet-applied, so you know it’s done right

If you notice signs of ear infection discomfort in your dog, it’s important to visit your vet for a proper exam and diagnosis. With Claro®, your vet can diagnose and treat the ear infection all in the same visit. You can trust your vet to ensure the entire dose of medication reaches deep into the ear canal, so there’s no need to deal with the stress or guesswork of at-home treatments.  

With Claro®, relief starts right in the parking lot!  

With these tips, talking to your dog’s vet about an ear infection is easy.

No frustrating OTC or at-home remedies

Treating an ear infection at home multiple times a day can be challenging for you and stressful for your dog. But since one-dose Claro® is vet-applied, relief from itchy ears is easy. Avoid the hassle of messy over-the-counter and at-home remedies with ear infection treatment you can count on.
