Antibiotics for dogs are medications designed to combat bacterial infections. “These infections can affect various parts of the body, such as the skin, respiratory system, urinary tract, or gastrointestinal system,” says Jessica Apted, DVM, regional medical director for Sploot Veterinary Care‘s Denver metro locations. Antibiotics work by either killing bacteria directly or preventing the bacteria from multiplying, allowing the dog’s immune system to eliminate the remaining bacteria and heal the affected tissues, Dr. Apted explains. Dog antibiotics come in different formulations to suit your pet’s specific medical needs and other considerations, including your ability to administer the medication on a certain schedule. These include: Tablets and capsules: These are the most common formulations, and some antibiotic tablets are even flavored so your dog eats it like a crunchy treat. Not all dogs are fans of swallowing pills or capsules. Hiding tablets and capsules in pill pouches, like Greenies Pill Pockets, can help. Liquid antibiotics: Ideal for dogs who struggle with pills, liquid antibiotics can be given into the mouth via syringe. Topical treatments: Antibiotic creams, ointments, or sprays are used for skin infections, wounds, or hot spots. Ointments that contain multiple ingredients (antibiotics, anti-inflammatory medication, anti-yeast medications) are commonly used for ear infections. Injectable antibiotics: These medications, which are typically administered in a clinic setting by a veterinarian, are often used for severe infections or when oral medications aren’t an option.,Jump to section What Are Antibiotics for Dogs?
