The American Cocker Spaniel is classified by The Royal Kennel Club within the smaller ageing band, typically weighing 10–13 kg as an adult, with a median life expectancy of around 13.3 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Developed in the United States from English Cocker Spaniel stock and bred for a smaller frame and longer, silkier coat, the American Cocker Spaniel is gentle, affectionate, and eager to please.

What this means for your American Cocker Spaniel

The breed's long, low-set ears restrict airflow and are prone to infection, so regular checking and cleaning matters throughout its life. Progressive retinal atrophy, an inherited condition that gradually affects eyesight, is also seen in the breed — regular eye checks can help catch it early.

American Cockers can be prone to weight gain as they age, which puts extra strain on joints already susceptible to hip dysplasia, so keeping an eye on portion sizes becomes more important in the senior years.

When is an American Cocker Spaniel considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, small breeds like the American Cocker Spaniel are generally considered senior from around 10 dog years old.
