In short

A 5-year-old Cocker Spaniel is about 37 in human years, and a 10-year-old is about 60.

In a 2024 study led by Dogs Trust, published in Scientific Reports, which looked at more than half a million UK dogs, half of Cocker Spaniels lived to 13.3 or older. That's longer than dogs overall, and about the same as a person reaching 75.
