Dr. Lee introduces you to some of the common medical problems seen in our geriatric dogs and cats that might result in their demise. A geriatric pet means that they are in the last 10% of their estimated life—which can be a hard for both you and your pet. By understanding conditions such as osteoarthritis, decreased sensory and cognitive function, and skin masses, you will be better prepared to deal with them if these medical conditions become an issue.
