According to a recent survey, 98% of veterinarians believe older dogs have different medical needs. And 91% said they could detect disease earlier if they saw their patients more often. Plus, because 1 year of a dog's life equals approximately 7 human years, canine illnesses can progress rapidly. For all these reasons, senior dogs should have a complete examination at least twice a year. Your veterinarian at the Animal Care Center may also prescribe medications for arthritis, canine cognitive dysfunction syndrome and other age-related diseases.
