Taking a yorkie at home is a commitment that is not taken lightly.  If you can’t take care of this dog for 15 years, it is better to postpone buying one until you are ready to do so. Now that you have an idea about the lifespan of Yorkshire terriers, take note of the age when they will become prone to illness and injury. More trips to the vet are needed. Arthritis is the most common illness for them but the good news is that there are medications to ease the pain and improve their life. Remember that their lifespan can reach up to 15 years so make sure you give them the best life possible.
