One of the worst incidents at the dog park that happened to us was when a little bitty jack russell tried to chew Neo thru the fence! No wonder her owner had her in with the big dogs! This dog was so psyco she spent the entire time we were there trying to get under the fence or chew thru it! Her owner was completely oblivious - just kept making excuses that she just wanted to "play". Just goes to prove that not all dangerous dogs are the big ones. Bostons also seem to have a "thing " for Neo's throat, too.
