ToggleWhat is Clavacillin?
Clavacillin is a veterinary antibiotic composed of two active ingredients: amoxicillin and clavulanate potassium. Together, these compounds work to treat various bacterial infections in dogs. Amoxicillin is a penicillin-type antibiotic that kills bacteria, while clavulanate potassium inhibits the enzymes that may otherwise protect bacteria from antibiotics.
Clavacillin is manufactured specifically for animals and is not the same as the human version of amoxicillin-clavulanate, which may contain ingredients not safe for pets. Always consult a vet before using any medication on your dog, even if it seems similar to what humans take.
Why Use Clavacillin for Dogs?
Veterinarians commonly prescribe Clavacillin for dogs when they suffer from infections caused by susceptible strains of bacteria. These may include:
- Skin infections (abscesses, wounds, and cellulitis)
- Urinary tract infections (UTIs)
- Respiratory tract infections
- Periodontal (gum) disease
- Soft tissue infections
The antibiotic works by targeting the bacteria’s cell walls, effectively killing them and stopping the spread of infection. By combining amoxicillin with clavulanic acid, Clavacillin offers a broader spectrum of activity than amoxicillin alone, making it effective even against bacteria that produce beta-lactamase enzymes.

Proper Dosage of Clavacillin for Dogs
The dosage of Cloxacillin for dogs depends on several factors, including the dog’s weight, the type and severity of the infection, and overall health. It’s crucial to follow your veterinarian’s instructions precisely.
Typically, Clavacillin is administered orally twice a day. The dosage is usually calculated as 6.25 mg per pound (13.75 mg/kg) of body weight, every 12 hours. For example, a 20-pound dog would require approximately 125 mg of Clavacillin every 12 hours.
Clavacillin is available in tablet and liquid forms, and it’s essential to complete the entire course of the medication even if your pet starts to show improvement early.
How to Administer Clavacillin to Your Dog
Clavacillin tablets can be given directly or hidden in food if your dog resists taking pills. For liquid suspension, shake the bottle well before measuring the correct dose. Using a syringe or dropper can help ensure accurate administration.
Here are a few tips:
- Administer with food to minimize the risk of stomach upset.
- Always ensure fresh water is available.
- Store the liquid form in the refrigerator and discard after 10 days.
- Monitor your pet for side effects and report any concerns to your vet immediately.
Possible Side Effects of Clavacillin for Dogs
While Clavacillin is generally safe when used as prescribed, some dogs may experience side effects. Common side effects include:
- Vomiting
- Diarrhea
- Loss of appetite
- Lethargy
Less common but more serious side effects may include:
- Allergic reactions (swelling, rash, difficulty breathing)
- Seizures (in rare cases)
- Liver dysfunction (especially with long-term use)
If any adverse reactions occur, discontinue use and consult your veterinarian immediately. Never attempt to adjust the dose on your own without professional guidance.
Precautions When Using Clavacillin for Dogs
Before starting Clavacillin for dogs, your vet will evaluate your pet’s medical history. The medication should not be used in dogs with known allergies to penicillin or other beta-lactam antibiotics.
Important precautions include:
- Avoid use in pregnant or lactating dogs unless specifically advised by your vet.
- Inform your vet about any other medications your dog is taking to avoid drug interactions.
- Do not skip doses or stop the treatment early, as this may lead to antibiotic resistance.
