Since my guy is just 9 months old...I don't know yet how he will be at full grown! But I've read enough here to think your gal will still put on some weight..mostly fill out until about 2. They come in all weights and sizes! But bet she's perfect! We have had a few threads here on growth..my Jake weighs 42 lbs and he'll probably be on the smaller side of male bullies...but he's so perfect and healthy...I don't think much about it. You might do a search for this subject on older threads..but I KNOW Maggie is perfect!
