Palmer met Oreo recently (my aunt's 12-year old chihuahua) and the two seemed to hit it off quite well... most especially since Oreo kept trying to jump on to Palmer's backside. The second meeting was bordering boring since the two didn't seem to care the other dog even existed. They meandered around the house without any sort of interaction, save a sniff here and there. Palmer got a bit territorial when he was chewing on his rawhide once but other than that, the two existed in perfect harmony.
As much as Johnny hates when we dress Palmer up, we put him in Oreo's hat for a bit. Palmer entertained us for a few seconds but took it off when he realized he wasn't getting a treat for wearing it. Anyway, from Johnny, Palmer, and I... Have a merry Christmas and a happy New Year!
