The Chihuahua has an average lifespan of 14–16 yrs. Luxating patella, heart disease, and dental issues are frequent. Despite their size, they can be surprisingly durable.
Veterinary costs vary by breed. Larger dogs and brachycephalic breeds often incur higher lifetime expenses. Always buy from health-tested breeders or adopt from a reputable rescue.
Exercise & Training
Rottweiler exercise needs: Moderate–High energy. The Rottweiler does well with 45–60 minutes of exercise daily and benefits from variety to prevent boredom.
