Pet Health

Pets can add fun, companionship and a feeling of safety to your life. Before getting a pet, think carefully about which animal is best for your family. What is each family member looking for in a pet? Who will take care of it? Does anyone have pet allergies? What type of animal suits your lifestyle and budget?

Once you own a pet, keep it healthy. Know the signs of medical problems. Take your pet to the veterinarian if you notice:

Loss of appetite
Drinking a lot of water
Gaining or losing a lot of weight quickly
Strange behavior
Being sluggish and tired
Trouble getting up or down
Strange lumps
