What Is Erythromycin?
Erythromycin is a type of macrolide antibiotic that helps treat a wide range of bacterial infections. It functions by blocking the production of proteins bacteria need to grow and multiply.
In veterinary medicine, Erythromycin is often prescribed off-label for dogs. This means it isn’t FDA-approved for canine use, but veterinarians can still legally prescribe it when they determine it’s appropriate. It’s important to always follow your vet’s guidance when giving Erythromycin to your dog.
Common Uses of Erythromycin for Dogs
Erythromycin is primarily used to treat gram-positive bacterial infections, but it also has some activity against certain gram-negative bacteria. Vets may prescribe it for:
- Skin infections
- Wound infections
- Respiratory tract infections
- Eye infections
- Gastrointestinal infections caused by Campylobacter or other bacteria
In some cases, it may be used as a prokinetic agent in dogs to help with delayed gastric emptying due to its effects on motilin receptors.
Erythromycin Dosage for Dogs
The correct Erythromycin dosage for dogs depends on the dog’s weight, the severity of the infection, and the specific condition being treated.

This can vary based on the form of the drug (tablet, capsule, suspension) and whether it’s being used as an antibiotic or a prokinetic agent.
