I'm really sorry the sweet girl had that problem! I honestly thought that goldens and labs were always sweet dogs...but my friend Lindsey had a black lab when she was growing up, and one day the dog just FREAKED OUT! It bit her head (she was about 6 or 7 at the time) and ripped her scalp back. She had to have something like 100+ stitches to fix her head. This is why she hates dogs now...she's just so terrified of them, especially black ones! And I saw labs not being so nice just last night with Bull and his sister Shadow. There was teeth baring, growling...basically a complete dog fight! Bull even made Shadow bleed! Thankfully they're only 7 weeks old, so I was able to yell and it scared them off each other! I just hope this doesn't continue on into their adult years. And we (me and the BF) got them from a BYB, well, actually a post office back parking lot breeder!
