I'm not sure if you meant to ask "when" boxer mix dogs are full grown, or how large they are? I would consider a medium-sized breed like a boxer mix to be full grown at around 12 months of age. As far as size, Boxers are medium-sized dogs that usually weigh around 60 lbs or so. Depending on what Chloe is mixed with, she might be this size as an adult, or could be a bit larger or smaller.
