- Small breeds (e.g., Chihuahuas, Toy Poodles): 12-15 years
- Medium breeds (e.g., Beagles, Cocker Spaniels): 10-13 years
- Large breeds (e.g., German Shepherds, Golden Retrievers): 8-12 years
- Giant breeds (e.g., Great Danes, Mastiffs): 7-10 years
However, it's important to note that these are just averages, and individual dogs can live longer or shorter than the typical range for their breed. Good nutrition, regular exercise, and proper veterinary care can all contribute to a longer, healthier life for your furry friend.
