Ooh that's a big puppy.
Desmond was only around 25-30 lbs at that age, but I don't remember how tall he was. He's 10 months now and is 50-55 lbs and 24 or 25" tall, though. It sounds like your pup still has a good bit of growing to do and may be on the larger side of standard poodles. But honestly I'm not sure how much more growing my own pup has to do, so I can't give you much input on how yours will grow.
