Anyone who lives with animals knows it all too well: A minor slip, a scratch in the barn, or a scrape after playing—injuries are simply part of everyday life. And then there’s that anxious question again: What can I apply to my pet’s wound without causing more harm than good?
When I think of the medicine cabinet from my childhood, an image immediately appears in my mind: a rust-colored ointment. I was constantly on the move—and just as often covered in scratches. After every fall, first came the disinfectant, then a bandage with this mysterious ointment. It worked almost like magic and noticeably sped up healing.
Later in the horse stable, I encountered it again: Betaisodona, ubiquitous for small scratches and scrapes. But at home, it was strictly forbidden—it was never to be used on the cats. Why is that? And what about dogs? 1
What Exactly Is Betaisodona?
Betaisodona is available as a solution or ointment and contains the active ingredient povidone-iodine. This releases iodine, which reliably kills bacteria, viruses, and fungi. In human medicine, Betaisodona is primarily used for skin disinfection before surgeries—to eliminate germs and reduce the risk of infection.

Can I Use Betaisodona on My Animals?
The answer is often disappointing: It depends. Every organism reacts differently to active ingredients—a blanket recommendation is therefore not possible. However, it is clear: Betaisodona can generally belong in the emergency kit for horses and dogs. Still, wounds or skin infections should always be checked by a veterinarian.
Particularly with dogs, caution is advised. The application should only be done in consultation with a veterinarian—and above all, the dog must not lick the treated area. Ingesting povidone-iodine can be life-threatening for them. 2
Horses Can Be Treated with Betaisodona
When horses frolic with their peers in the pasture, small wounds can occur quickly. To treat these, some horse owners turn to the “all-rounder” from the stable pharmacy. However, it is essential to ensure that no dirt remains in the wound—hygiene is crucial. It helps to rinse the wound once and then apply the antiseptic. For deep and bloody wounds, a veterinarian should be consulted immediately. 3

For Cats, the Ointment Is Deadly
Betaisodona must not be used on cats—contrary to some widespread advice. Their bodies react sensitively to povidone-iodine—even small amounts can lead to poisoning and, in the worst case, be life-threatening. If you want to treat a small wound on your cat, you should use iodine-free products. Antiseptics with octenidine are recommended.
Conclusion
Betaisodona can be a valuable aid in many home and stable pharmacies—provided it is used correctly. While horses can be well cared for with it and dogs should only be treated after consulting a veterinarian, utmost caution is required with cats: Povidone-iodine is dangerous for them. To be safe in an emergency, it’s better to have an iodine-free antiseptic like octenidine on hand for cats.
