Chico is not a loner...
Instead, Chico hangs out with his gang, Buster and Olly! This particular picture was taking on the Montlake bridge in Seattle's U-District. Buster and Olly are Chico's best friends, we try to go and play with them once a week. Buster and Olly are actually brother and sister also, a few years apart. In fact, Olly is Chico's girlfriend (We actually don't worry about them being behind closed doors together, we've fixed that problem).
Actually, it's quite amusing. Buster will sit on the couch and watch Olly and Chico play. If one of them starts winning (because they play fight all the time), Buster will go and take control of the situation (usually chewing on the winners ears).
Chico also takes Buster and Olly to the dog park with him. It gives him a boost of confidence when he has his gang at the park with him. Just look out to those other dogs when the gang shows up!
