If you mean Italian Greyhounds their lifespan is approximately 12-15 years with proper care. IG's have many medical issues that they are prone to like bad teeth. You will need to brush their teeth daily otherwise plaque builds up, enters the blood stream and cause heart, liver and kidney damage, even failure. The also are extremely prone to broken legs. They are a hyperactive dog that needs plenty of room to run and play. If you are considering one of these as a pet, please visit an Italian Greyhound rescue to adopt one. You can find Italian Greyhound rescues (like mine) on petfinder.com.
