If you’re reading this, chances are you’ve just come back from the vet with a prescription for Clavamox for your dog and want to know more information about this drug.

Listening to your vet explain everything you need to know about a new medication can be overwhelming. It’s often hard to remember all of the important details, especially if you’re worried about your dog — or if your dog is doing their best to escape the room or burrowing under your arm.

If you still have questions about Clavamox, don’t panic. Here’s what you need to know about Clavamox for dogs.

What Is Clavamox?

Clavamox is a broad-spectrum antibiotic and is the veterinary equivalent of Augmentin for humans. To get a little technical, it’s a type of penicillin generically known as amoxicillin trihydrate/clavulanate potassium. Luckily for the average owner, the brand name of the drug, Clavamox, is much easier to say.

Clavamox was developed specifically for veterinary use in dogs and cats. It’s given orally, by tablet or suspension drops, to fight off bacterial infections and is most commonly used to treat the following:

The drug has been clinically proven to fight off several strains of bacteria, including Staphylococcus, Streptococcus, and E. coli, along with other strains of aerobic and anaerobic activity. In some cases, your vet might take a culture of the infection prior to prescribing Clavamox to make sure that the drug is the correct choice for the bacteria in question.

Clavamox isn’t used to treat viral or fungal infections. It’s also not effective against certain types of bacteria or infections caused by Enterobacter or Pseudomonas.

Side Effects of Clavamox for Dogs

The most common side effect of Clavmox is an upset stomach, including vomiting or diarrhea. As with any medication, some dogs may have an allergic reaction. Dogs with a history of allergies to penicillin shouldn’t take Clavamox. Discontinue giving your dog Clavamox and call your vet immediately if you suspect your dog is having an allergic reaction.

Symptoms of an allergic reaction in dogs include:

  • Swelling
  • Rash
  • Difficulty breathing
  • Increased heart rate
  • Fever
  • Vomiting
  • Seizures

Clavamox is generally well tolerated in dogs, but there are some other side effects to watch out for:

You should always talk to your vet about possible adverse reactions before administering a medication for your dog. Be sure you have a plan in place with your vet for dealing with an adverse reaction.

Dosage of Clavamox for Dogs

You should only give your dog Clavamox under the guidelines of your veterinarian. If you have questions about the dosage, talk to your vet before making any adjustments, as it could limit the effectiveness of the antibiotic.

You can also compromise the drug’s efficacy by shortening the course of treatment. While it might be tempting to stop giving the drug once your dog starts to get better, especially if you have a dog that’s difficult to medicate, failure to administer the entire course of antibiotics can lead to a relapse. You also increase the chances of the infection becoming resistant, meaning it’ll be harder for your dog to fight off another infection.

How to Give Clavamox for Dogs Safely

Clavamox is a generally safe drug, but there are some things you need to keep in mind when administering any new drug.

Observe your dog closely for any signs of an allergic reaction or adverse side effects, especially if this is the first time your dog has taken antibiotics. If possible, arrange for someone to check in on your dog if you plan on being away from the house for more than a few hours.

Talk to your vet about the best way to administer the drug and about any possible medication interactions. If your veterinarian prescribes oral suspension drops, remember to refrigerate them, as they’ll go bad very quickly if left out. Call your vet if your dog’s condition does not seem to respond to the drug.

The best way to get answers to questions regarding your pet’s medications is to talk to your prescribing veterinarian. If you have concerns about giving your dog antibiotics or suspect your dog is having an adverse reaction, seek veterinary advice.
