i have a little german shepherd dog. i say little, she's like 45 lbs. that's little for a GS...anyway, she was a pound dog and they fixed her at like 10 weeks, so we think it probably stunted her growth.
(she's about 1.5 years old)
we still love her though. i named her the mighty quinn, after the song Quinn the Eskimo (the mighty quinn) written by bob dylan, made infamous by the grateful dead, and covered by phish (among others). I'm going to try to dig up a picture of her. she's the sweetest doggie in the world. and rambunctious as all hell.
