That how my pit mix is, she just keeps going and going. She'll be dead asleep, dreaming and all and as soon as you get up she's up full energy like she's been running the entire time. She's only 2, coming out of those puppy years, so she still has a lot of energy. My turvuren will play sometimes, but she's 5 and calmed down and sometimes, she just doesn't want to be bothered. My newfie is 8 and she definitely takes after the newfie part of her, she's calm. All she needs is an open door to look out of, and someone to let her out a few times and give her some lovin every now and then. She's my dominant dog and definitely runs the show around here, lol, well at least from the dog's standpoint.
