The English Cocker's 5/5 with children and 4/5 with other dogs and strangers describe a genuinely easy dog to take places. It is busy, cheerful and interested in everything, and it settles when the day's work is done.
The 2/5 for time alone is the caveat. Cockers are closely bonded and long unbroken absences produce vocalising and door-directed destruction. Absence training from the first week, regardless of your current schedule, is the standard prevention.
One thing worth raising with a breeder is temperament in the line. Sudden, out-of-character aggression has been reported historically in the breed, more often in solid-coloured dogs, and while it is uncommon and its causes are debated, a breeder who is willing to discuss the temperament of the parents and grandparents openly is worth more than one who deflects the question.
On money the Cocker runs $100–$200 a month against $110–$240, and $1,400–$2,900 against $1,700–$3,200 in the first year — mostly a weight difference, narrowed in practice by grooming and ear treatment.
Lifespan runs 12 to 14 years against 10 to 13.
