Cocker Spaniel size questions
How big does a Cocker Spaniel get?
The American Kennel Club gives 25 to 30 lb (11 to 14 kg) for males and 20 to 25 lb (9 to 11 kg) for females. Individual dogs can fall outside a breed range, and a mix or a dog from working lines may be larger or smaller.
When is a Cocker Spaniel fully grown?
On this curve a male reaches half of adult weight at about 18 weeks (4 months), 90 % at about 54 weeks (13 months) and 95 % at about 76 weeks (18 months). On this curve a female reaches half of adult weight at about 19 weeks (4 months), 90 % at about 61 weeks (14 months) and 95 % at about 80 weeks (18 months). These ages come from the shape of the published growth chart for small-medium dogs, scaled to the AKC weight, so they describe a typical dog, not a particular one.
How much should a Cocker Spaniel puppy weigh at 6 months?
A typical male is about 18.5 lb (8.4 kg) and a female is about 14.6 lb (6.6 kg) at 26 weeks on this curve. The range for healthy puppies is wide, so use the calculator above with your own puppy’s weight.
