About the Spanish Water Dog's ageing

The Spanish Water Dog is a medium breed with an average lifespan of 10 to 14 years. Like other medium-sized dogs, the Spanish Water Dog ages most rapidly in its first two years — reaching the rough equivalent of a 24-year-old human by its second birthday — and then ages more steadily.

Spanish Water Dogs typically reach senior status around 8 years old. From that point on, screening for joint, dental and weight-related conditions becomes especially valuable. Medium-class breeds tend to be prone to dental issues and weight gain in middle age, so dental care and portion control pay off.

If your Spanish Water Dog is approaching the high end of its expected lifespan (14+ years), you're already doing something right. Continue to monitor mobility, appetite, weight and behaviour — and adjust food, exercise and vet check-up frequency accordingly.
