This medication may be a tablet, a capsule, or a liquid that you give to your dog by mouth. You can hide the tablet in a doggy treat, in cheese, or other dog food to help encourage your dog to take this medication.  If your dog spits out the pill,  gently keep it in the dog’s mouth to ensure your four-legged buddy swallows it.

If your dog has been prescribed this medication, it is always recommended to give the entire prescription. Part of any wellness plan is completing the medication prescribed. Unless your vet tells you otherwise. This helps decrease your chance of causing cause your dog to develop antibiotic resistance.

Dosing instructions For Amoxicillin

Amoxicillin is dosed based on your dog’s body weight and what infection your vet is trying to treat. A typical dosage used by many vets is 5 to 10mg per pound. This means a 50-pound dog would need to take 500mg twice a day.

This is usually given for 10 to 14 days. Sometimes this may even be given longer. Amoxicillin starts working in your dog and continues for 12 to 24 hours. Make sure that you do give your dog the entire course of antibiotics to prevent your dog from developing a resistant bacterial infection.
