I just adopted a boxer puppy - she was dumped off at my parents' house in the country and came home with me - and was trying to get an idea of her age. She's about 20lbs (she was skinny when I got her and has filled out nicely in the last week - she looks like she's supposed to now) and about 17" at the shoulder. Looks like she still has all of her baby teeth. We haven't been to the vet yet, (my sister works for a paper that provides free spaying or neutering and first vet visit for animals adopted through them so I'm waiting on my certificate) but I'm not sure how much he'll be able to tell me about an approximate age. Thanks in advance for any help!
