I have 2 boys from the same litter, they are almost 2 years old. One is content to sleep on my lap all day! The other though, he is a bundle of energy still. He cannot sit still for a minute! When he finally does sit down, every little noise sends him rocketing off the couch or bed barking up a storm.
I play fetch with him everyday for at least 15 mins until he stops and then we play on the floor and do tricks and Im always giving them tons of attention, but he is never tired it seems!
I walk them for a 1/2 hour at night after work when the weather is nice, they love to walk and they sleep good when we go to bed, but even after the walk he wont settle down until we actually go to bed. Even though you can tell hes exhausted!
