Training and intelligence
Cocker Spaniels are not the most intelligent dogs, but they make up for this in enthusiasm and wanting to please.
Temperament
Cocker Spaniels love their families, especially children, in fact they love everyone. These are happy, affectionate dogs whose tails virtually always wag.
Attitude towards strange dogs and people
Everyone is a friend to a Cocker Spaniel, and they want to greet them warmly. Some may have a tendency to shyness, which good socialisation will help.
Grooming and shedding
Cocker Spaniels are medium shedders, their coat will grow very long, but can be clipped short for easier maintenance.
Exercise
They like lots of exercise. Cocker Spaniels are the smallest of the gun dogs so they have plenty of exercise and stamina.
Need for company
Cocker Spaniels like to be with their people best, but will tolerate being left for short periods.
General
Cocker Spaniels can be difficult to housebreak, and some love to bark just because they enjoy it; persevering with training will help with either of these problems. One of the worst problems with this breed is that popularity has lead to some doubtful breeding - make sure you get your dog from a reliable breeder.
