If you are a dog parent, chances are you will need to give your pet antibiotics at some point. There are several antibiotics that are regularly prescribed to dogs for infections and other issues. Knowing ahead of time what to expect will help you to handle medical issues easier.


Tetracycline is available in both capsules and liquid form. It is used to treat respiratory infections and infections of the skin. It is also used for Lyme disease and Rocky Mountain fever. Dairy clashes with this drug, so giving cheese treats or any other dairy foods needs to be avoided when using it. Tetracycline can cause stomach upset and diarrhea, so your furry pal may need more frequent potty trips or a medication to ease the symptoms.


Cephalexin is a broad spectrum medication and is used to treat a large variety of illnesses in dogs. It is commonly used for infections involving the lungs and the skin but may also be prescribed for other canine health issues. It is also commonly prescribed for urinary tract infections. Cephalexin can also cause stomach issues in your dog and an additional medication to control diarrhea may be needed.


Enrofloxacin comes in chewable tablet as well as liquid drop form to be used for ear infections. It is used to treat a wide variety of issues, covering everything from liver and lungs to intestines and urinary tracts. Enrofloxacin is generally avoided in small puppies since it can cause lesions on cartilage and may inhibit growth. Dogs taking Enrofloxacin may exhibit a loss of appetite and general lethargy.


Amoxycillin is available in tablet and in liquid form. The liquid version must be kept refrigerated once it is mixed. Amoxycillin is used for infections of the skin and for abscesses. It is also commonly prescribed after general surgical procedures to prevent infections from occurring. The most common side effects of Amoxycillin are nausea and vomiting.
