It actually does seem like they are sometimes. One lady brought a pair of them to the dog park and they were so amped up and hyper that they were overheating but they wouldn't stop running around. They were probably close to dying, literally having runny eyes and squirting shit as they were running. If a group of other owners hadn't caught up to them and thrown them in the dog bath to cool them down I'm positive they would have run themselves to death.OMG I thought these dogs just looked retarded, but they actually act like it too? This dog totally has down syndrome eyes. And maybe they're good at fighting because they have the dog equivalent of retard strength.
