I had posted about a month ago when we adopted this girl, she was a stray from South Florida. When we first got her, we thought she was a ~6-7 month old GSD puppy. Well, we've had her for a month and she hasn't gotten any bigger (besides putting on 5 lbs or so because she was skinny when we got her.) Our vet thinks she is about a year, based on her teeth, and won't get any bigger. She weighs right about 50 lbs. Everyone that sees her automatically assumes she is a GSD puppy, the only differences I have seen is her snout is slightly shorter, and ears a bit smaller, then a purebred. That said, any guesses as to what she is mixed with? Her personality is all GSD. Very, very smart, loyal to my wife and I, lots of energy outside, but after a day of exercise, she thinks she is a 50 lb lap dog.
