Nothing yet. I don't see it ever changing. Jackson will be 2yrs old in October. He's a 16lb Yorkie and/or Silky Terrier, don't know. Anyways, he's the most go-with-the-flow dog. He prefers canine company rather than humans. We try to get to the dog park once a week (usually Saturday) and he really enjoys. He has certain days where he runsrunsrunsruns like a mad man, but other days he is more content to chill, sniff everyone, walk around, lay in the baby pool, etc. It all depends on weather and his mood really. He's never ever once shown aggression for another dog or anybody. I've never seen him growl, curl a lip, or anything. He barks playfully in a bow position to see if a dog will chase him, and usually it works. If not, he just walks away.
Any dog can come into our house, our car, our space, etc and he greets them with a warm welcome. He can go into anybody's elses home with a dog and fit right in.
I feel really blessed to have been granted a dog like Jackson. He literally has no behavioral problems. Besides the fact that he turns into somewhat of a spazz at my dads home (where we visit 1-3x per week, 2 other dogs, 2 cats, and 3 other humans, plus big fenced in yard with big pool, hot tub, etc) so he just gets excited. That's the only thing I can think of 'bad' about him and it's not even bad, lol. Oh and he's shy with strangers. Never aggressive, or really 'fearful' per say, he just prefers for humans (that he doesn't know) to ignore him. He will go up and sniff to say hey, but once they come to pet him, he backs away lol. We've been working on this though and he's gotten sooo much better at human greetings.
Anyways longer post than I wanted.
