Puppy to adult weight

[ihatethecold]

My puppy is 13 weeks old and weighs 22lbs,

I have read somewhere that at 12 weeks they are half their adult weight.

Anyone else know if that's correct?

I've answered my own query, 45lbs apparently!

I wouldn't believe that site...I put in past weights and ages for mine and got adult weights of between half and two thirds what mine is at 9 months, never mind as an adult.

Oh great!!!

It's very, very breed dependant as different breeds have growth spurts at different times. Take for example a Leonberger they are often only one fifth of their adult body weight at this time.

Exponential growth tends to continue to about 20 weeks and then slows. Hence feeding regiemes.
