Hi!

My mini f1b goldendoodle Charlie is 19 weeks / 4 months and 1 week exactly. As of right now, he is 21 pounds and he has grown at least a pound a week for as long as I can remember. I feel as though if he were to stop growing this very second, he would still be a 25-30 pound dog just by filling out. However, he is still growing pretty quickly. My vet seems to think he will only be 30-35 max, but I'm thinking 40 at least. Does anybody else have a doodle who was around this size at his age? Any size that he might get is fine, as my only concern was that he would be less than 20 pounds full grown HA (there was a pup in the last litter who was only 13 pounds). His parents are both under 30 pounds. Thanks!!!

Well, Charlie is 14 months old now! He was 36 pounds at 12 months, and when I weighed him a month ago at 13 months he was 37.5 pounds. He's probably 38 by now at LEAST! He's being groomed Sunday so I'll weight him there. He ended up being the most perfect size for me!!

Wow!  He really is larger than you expected. He really is a nice size.
