Clavamox for Dogs – Dosages, Side Effects and Safety Tips!

As a dog owner, you should be interested in knowing more about some essential medications.

Clavamox for dogs is definitely on top of that list.

You might have encountered this word when you had a consultation with your vet. He or she could have prescribed it to your dog who wasn’t keeping too well.

Well, Clavamox is a medication administered by a vet to your dog, and it is a broad spectrum antibiotic. You will need a prescription to get this FDA-approved drug. You can find Clavamox in the form of oral drops and tablets.

What is Clavamox?

Clavamox is a drug that is formed by combining Amoxicillin and Clavulanate Potassium. It is used to treat an array of infections caused by bacteria such as Cellulitis, Skin infections, Abscesses, and also wounds in dogs.

Some bacterial infections are resistant to the impacts of Amoxicillin alone. With this special mixture, you can treat those infections effectively. But bear in mind that the side effects of using Clavamox might be a little harsher than the plain Amoxicillin variants.

Clavamox for Dogs – Dosage

This is a prescription drug.

Even if it is one, it is very important to stick to the dosage once you get your hands on it.

Follow the dosage prescribed by your vet to the letter and there won’t be any problems.

Below is a general guideline and it is only for informational purposes (though this is what your vet will tell you except for in exceptional cases).

The optimum Clavamox dosage for dogs is about 6.25mg/lb of your dog’s body weight twice a day. This is for tablets, and when it comes to liquid, it is about 1ml/10 lbs of the dog’s body weight.

If you are planning to go the liquid route, then remember to keep the solution in the refrigerator without fail. And also, be sure to replace the medicine after a period of 10 days.

Clavamox is usually available at the pharmacy in tablet form at strengths ranging from 62.5 mg to up to 400 mg, where the perfect strength for your pet dog would be decided by the veterinary doctor himself or herself.

This medication is also available in a liquid suspension from where it contains 50 mg of amoxicillin and 12.5 mg of Clavulanate potassium per milliliter.


  1. If you are treating soft tissue or skin infections with this drug, the average period of medication will be 5 to 7 days. In case your pet stops responding to the treatment after taking it regularly for a period of three days, you would have to consult your veterinary doctor without fail.
  2. Even though it has been seen that the treatment of certain bacterial infections in dogs such as the urinary tract infection takes longer to heal than the others, care should be taken that the medicine is not administered to your pet for more than 30 days. Doing so might result in grave results and side effects.
  3. It is important that you complete the treatment for the prescribed period as told by your vet. Do not stop giving the medicine to your pet before the dosage finishes. If you do so, then there are good chances that the infection might actually make a return which just means more trouble for your friend.
  4. If you have missed a dosage, don’t panic. If you realized it only some time later like 30 minutes, administer the missed dose. If it is already time for the next dose by the time you realize, skip the missed one. Never give two dosages at the same time!

Clavamox for Dogs – Side Effects

Clavamox brings some excellent benefits when you are dealing with bacterial infections and other issues.

But like every other drug on the market, this too will have some side effects depending on the dog.

You might be following the dosage to the letter, and still some reactions may pop up. You don’t have to worry as most of them are mild and nothing serious.

This drug can also interact with other drugs like Tetracycline and Chloramphenicol and may result in some trouble to your dog. There are also chances of absolute resistance that is not the severe.

Some of the major side effects associated with Clavamox include:

  • Allergic Reactions: One of the most common side effects that Clavamox can result in is allergies. Symptoms here include breathing difficulties, swelling, fever, vomiting, rashes, increase in heart rate and even seizures. In case you encounter any such issue, taking your pet to the vet immediately is the best thing to do.
  • Diarrhea Woes: Another side effect that is very regular is diarrhea. This is mainly caused by the sudden change of bacterial population inside the animal’s intestine. Watch out for the level of diarrhea. If it is beginning to be too much, call your vet.

You can also watch out for loss of appetite and also yeast infections in some cases.

At times, the issues of neurotoxicity might also arise in case the medicine dosage goes up to a long period of time and in high dosages as well. The neurotoxic effect causes confusion and coordination issues in the pet.

Safety Precautions

You have to be careful and mention all the medical history to your vet before he prescribes your dog Clavamox.

Dogs with a history of hypersensitivity to the group of antibiotics such as cephalosporin and penicillin do not go well with Clavamox.

Also, don’t give your dog this medicine if she is pregnant, lactating, or breeding.

It might look like a lot of work, but be open to your vet about these things and he’ll take care of the rest.


Clavamox is great for your dog when you need to fight his bacterial infections.

It is also approved by the FDA, so you don’t have to worry about doing anything sneaky here.
