The recommended Enrofloxacin dosage for dogs is 5-20 mg/kg for the treatment of infections in dogs that don’t respond to other antibiotics. These infections include skin infections, pneumonia, and urinary tract infections.
Enrofloxacin Dosage for Dogs by Weight
The appropriate dose of enrofloxacin depends on a number of factors:
- Dog’s body weight

This is simply a multiplication of the dog's weight by the dosage level prescribed.

How a Calculator Works
Most veterinary dosage calculators involve three steps:
- Enter the weight of the dog (kilograms or pounds)
- Choose the range of dosages recommended by a veterinarian.
- The calculator takes the weight and multiplies it by mg/kg dosage to estimate the daily dose.
Advantages of Enrofloxacin For Dogs Dosage Calculator

Common Uses of Enrofloxacin for Dogs
Veterinarians prescribe enrofloxacin for all kinds of bacterial infections.
- Urinary Tract Infections
Dogs affected by bacterial UTIs may be treated with enrofloxacin as it penetrates urinary tissues well.
- Skin and Soft Tissue Infections
Some common uses of this antibiotic include:
- infected wounds
- abscesses
- dermatitis by bacteria
- Respiratory Infections
Enrofloxacin may be helpful in treating infections which affect:
- lungs
- bronchial tubes
- upper respiratory tract
- Ear Infections
Some bacterial ear infections are well treated with fluoroquinolone antibiotics.
How Enrofloxacin Works
Enrofloxacin is a fluoroquinolone antibiotic drug. These drugs disrupt the function of bacterial enzymes such as DNA gyrase and topoisomerase that are required for DNA replication in bacteria.
When these enzymes are inhibited:
- Bacteria cannot reproduce
- Infection growth stops
- The remaining bacteria are destroyed by the immune system
Because of this mechanism, enrofloxacin is said to be bactericidal, meaning that it actually kills bacteria rather than slowing their growth.
Side Effects of Enrofloxacin For Dogs
Although generally safe if prescribed correctly, there are some dogs which may experience side effects.
Common side effects include:
- Vomiting
- Diarrhea
- Loss of appetite
- Lethargy
Less common but more serious effects can be:
- Neurological symptoms
- Joint Problems in Growing Puppies
- Hypersensitivity reactions
Because fluoroquinolone antibiotics can have an effect on the development of cartilage, veterinarians generally do not want to use these antibiotics in the young, growing dog, unless required.
