please could you tell me, at what age approx a lab puppy reaches his max height and weight. my lab pup barney is
5 months old and weighs approx 24kg. is that a good weight for him.

thanks cliff.

Hi Cliff,
Most medium sized breeds like a lab reach their maximum height at about 10 months or so, and mature weight at about 18 months. There isn't a recommended weight for labs (a show-bred males height should be about 22" at the shoulder) but it should be right for the dog - ie you should be able to feel the ribs without squidging through layers of fat.
Hope this helps.
:)
