Lets see- Justice is an old soul. I swear he was born sensible. Now he was active and needed his mind and body stimulated(would run though the house and do kick flips off the cabinets) but he was incredible focused even at 6 wks which was the first time I met him. When I got him at 11 weeks he was like an adult. Seriously he was unreal. He never chewed anything, never got into trouble. He was free in the house by 9 months. Went straight though obedience classes and was learning Open at 10 months and had his first CD title at 14 months. He does still bounce around on occasion at 11.5yrs just like he did as a puppy.
Ember who is Justice's niece was a quick maturing puppy too. I think she was starting to mellow at 1 yrs and really started to settle by 1.5 yrs. But like a fine wine, Ember is still mellowing at almost 9. She was a surly pup and now she seems to be having more fun in life but in a different way. It is weird.
Diva, ah Diva. The brain really started to come in the mail around 2.5yr and she was pretty mature by 3yr. But mellow is never a word I would have called Diva. ADD yes, mellow no.
Birch again is not mellow. He is ready to go at the drop of a hat. But at 2yr 3 months he is pretty mature. He naps in the chair with me most evenings and He finally graduated to sleeping outside the kennel at night a couple months ago. But then just when I think all is good he brings me a sock he stole from somewhere or is found ripping up the newspaper(just this afternoon, sigh)
