Liquid Amoxicillin Dosage for Dogs

Pet Medications

Amoxicillin is a penicillin antibiotic than can be used in dogs.  Dosage for dogs are calculated by weight.

The dosage varies from 10mg to 20mg per kilogram of weight given twice a day.  For example, a 22 pound dog equals 10 kilograms.  For that dog the dose would vary from 100mg to 200mg every 12 hours.

The FDA has approved a oral suspension for dogs known as Amoxi-Drop®.  This suspension has a concentration of 50 milligrams per mL.  To continue with the example above the dog would receive 2 to 4mL by mouth twice a day.


The liquid form for humans is available in the concentrations 200mg/5mL, 250mg/5mL and 400mg/5mL.  If your veterinarian approves the use of the liquid for humans, be sure the dose is converted correctly — the concentration is different and will require that a different volume of the liquid be given to the dog.

Liquid Amoxicillin side effects in dogs are generally mild.  Do watch for signs of allergies like itching and rash.  Nausea, vomiting and diarrhea may occur.  Always contact your veterinarian immediately if you believe your dogs is suffering from side effects or allergies.
