My vet made mention that Chloe was very small at her 10 week apt. She was 8lbs 1 oz, which I have no idea, but it's been 13 years since I've had a boxer puppy. Our last boxer female was only 45ish lbs full grown, but she had immune issues and was the runt of the litter. I found a calculation online for a boxer and plugged in 8lbs at 10 weeks and it said she wouild be 20 lbs full grown, which I highly doubt. I don't care either way, but I think I bought way to big of a crate if she's not 55+ lbs!
