Clavamox, also known by its generic name, amoxicillin and clavulanate potassium, is an FDA-approved, broad-spectrum antibiotic medication for dogs, used to treat a wide range of infections, particularly those that may be resistant to other types of antibiotics.

Clavamox usually comes in the form of meat-flavored, chewable tablets to make it easier and more palatable for dogs to consume. It contains a special ingredient that neutralizes the particular enzyme that protects bacteria from antibiotics. Once this enzyme is neutralized, the medication is able to destroy the bacteria. From Staphylococcus to Streptococcus and E. coli, Clavamox is effective against many stubborn bacterial infections.1

This medication contains a combination of penicillin (specifically amoxicillin) and clavulanic acid, which makes it highly effective against many different types of common bacteria.2 It has been used effectively in dogs and cats for 30 years. It is important to note that Clavamox is not suitable for the treatment of viral or fungal infections. Speak to a vet to find out if Clavamox is the right medication for your pet.

Clavamox Uses

List of Clavamox uses

Clavamox was developed specifically for cats and dogs and can be used to treat any of the following conditions:1

This wide range of applications is why Clavamox is one of the most commonly prescribed pet medications in the U.S. It is safe for all breeds of dogs — from Chihuahuas to Great Danes and is available as tablets or drops.3

It’s regularly prescribed to treat soft tissue or skin infections, including wounds, abscesses, cellulitis, and dermatitis. In tablet form, it can also be very effective in treating bone infections, particularly in a dog’s mouth or teeth. If your dog develops a urinary tract infection, Clavamox is often a good choice of medication, as it has been proven to help with both mild and severe UTIs in dogs. In case of pneumonia or other respiratory illnesses, this medication is usually a vet’s first recommendation, although other treatment methods may be needed, depending on the severity of your dog’s respiratory distress.⁴

Clavamox side effects

Clavamox Side Effects

As with any medication, there are certain side effects that can happen as a result of taking Clavamox. Common side effects include:4

  • Diarrhea
  • Vomiting
  • Lethargy
  • Loss of appetite

These symptoms are usually normal and should not be a cause of great concern. However, keep an eye on your dog while they are taking the medication. Contact your vet if any of these common symptoms are severe, worsen, or don’t seem to go away.4

Serious side effects include a complete loss of appetite, fever, rash, and pale gums. These symptoms usually require immediate medical attention.

If your dog is experiencing severe side effects, it could be a sign of an allergic reaction to the medication. Additional symptoms of an allergic reaction to Clavamox are swelling, rash, difficulty breathing, increased heart rate, high fever, vomiting, and seizures.Every dog is different, so it’s important to always contact your vet or emergency veterinary services if your dog exhibits signs of illness when taking medication.

Clavamox Dosage & Administration

Clavamox should only be used with a prescription from a vet, who will be able to determine the right dosage for your dog, based on their weight, tolerance, medical history, breed, and any other relevant factors. Always check the prescription from your vet before administering medication to your dog. Clavamox doesn’t necessarily need to be given with food like some other medications, but if you notice that your dog is experiencing an upset stomach (such as vomiting or diarrhea), try mixing it in with their food.4

If your vet has prescribed Clavamox in liquid form, make sure to measure it precisely, based on a pharmacist’s instructions. Store it in the refrigerator and shake well before giving it to your dog. Your vet or pharmacist may provide measuring spoons or syringes to help with dosing.

Contact your veterinarian if you have a hard time getting your dog to swallow the medication or if you notice that they are experiencing stress when you try to give it to them. Make sure to be aware of how long your dog should be on Clavamox; a prescription refill may be necessary for longer treatment periods.

Clavamox Safety Information

It’s important to consider safety information when giving your dog Clavamox. Always inform your vet about any other medication your dog is taking — including vitamin supplements — as Clavamox can interfere with certain other drugs. This medication should not be given to dogs who are allergic to penicillins or similar drugs, nor to animals other than dogs and cats (especially not rabbits, guinea pigs, chinchillas, and other rodents).4

Seek emergency veterinary care or animal poison control if your dog gets too high of a dose. Vomiting is a common symptom of a Clavamox overdose and if left untreated it can lead to nervous system or liver damage.4

Final Notes

Clavamox is a broad-spectrum antibiotic for use in dogs and cats. It tends to be more effective than some other antibiotics, because it contains a combination of penicillin (specifically amoxicillin) and clavulanic acid, making it a good option in the treatment of bacterial infections. Clavamox is safe for all dog breeds and has been a common antibiotic prescription drug in veterinary medicine for decades. It is effective against pneumonia, urinary tract infections, infected skin wounds, dental disease, and respiratory infections.

Clavamox is available in chewable tablet and liquid form, with the latter usually being pork-flavored to make it more appealing for dogs to consume. This medication should only be administered with a vet’s prescription, because the dosage needs to be customized according to your dog’s breed, size, and overall health. Your vet will determine the length of treatment depending on the specific illness. Monitor your dog and be aware of the symptoms of allergic reaction and side effects.

Frequently Asked Questions

Who is Dutch?

Dutch is an online veterinary pet telehealth service, created by pet parents and board-certified veterinary specialists. We use a science-backed approach to provide pets relief for their everyday physical and behavioral health issues. Dutch connects you with licensed veterinarians over video chat and messaging to help you get care for your dog or cat quickly wherever you are — without the stress or expense of a vet visit. We also partner with pharmacies who can deliver prescription medication (in applicable states only) and over-the-counter treatments directly to your door. Dutch isn’t a veterinary practice or pharmacy, but a company that helps facilitate these services for pet parents to make veterinary care more accessible to all.

What is a visit with Dutch like?

When booking a video call with a vet, you'll be asked a few questions about your pet’s health issue. Depending on the issue, you may also be asked to fill out a longer questionnaire about their symptoms and share photographs of them so our veterinarians can better understand what’s going on. You’ll then pick an appointment time that works best for you.

During your video call, one of our licensed veterinarians will talk to you about the symptoms your pet is experiencing, ask you questions, review your pet’s medical history if you’ve provided it, and answer any questions you have. The vet will ask to see your pet and their environment. And they may ask you to perform some simple checks on them if needed.

After your video call, the vet will send you a message with a custom treatment plan to help your pet feel better, including a link to buy any recommended prescription or over-the-counter medications. Place your order and we’ll ship it free.

How much will it cost for Dutch to treat my pet?

The Dutch membership starts at $7/mo for unlimited access to the vet. No more long waits for appointments or surprise bills.

In addition to the base membership plan, our veterinarians may also recommend additional medication (Rx and/or OTC) that you will have the option of adding to your plan at an additional cost.
