Whippet size questions
How big does a Whippet get?
The American Kennel Club gives 25 to 40 lb (11 to 18 kg) for males and 25 to 40 lb (11 to 18 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 Whippet fully grown?
On this curve a male reaches half of adult weight at about 17 weeks (4 months), 90 % at about 46 weeks (11 months) and 95 % at about 69 weeks (16 months). On this curve a female reaches half of adult weight at about 15 weeks (4 months), 90 % at about 48 weeks (11 months) and 95 % at about 68 weeks (16 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 Whippet puppy weigh at 6 months?
A typical male is about 23 lb (10.6 kg) and a female is about 24 lb (10.7 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.
