Welcome to the world of non stop energy! We have a 9 week old (Archimedes) that is full of it. lol our solution is a tight schedule from play, to bathroom, to food. My husband and I both take turns, so it helps. Before he eats dinner around 6:30 p.m. we run him pretty hard... up and down hills, chasing games, and fetch. he calms down after that and wants to cuddle. Fortunately, we live on a large 3 acre property and play hard/run and/or fetch for about 4 hours a day. In the evening he is pooped! In fact today he was outside all day and hes been napping since 7:30! Typically, in order for him to sleep through the night with no whining, barking, etc... we actually co-slept with him instead of crate or separation and he's been perfect. Sharkies? We've had it all... I actually call it "shark week" hahahahaa gently grab the snout and firmly say "no bite". We've decided to give him fuzzy stuffed toys and excellent organic brown rice imitation raw hides and his little mouth is preoccupied for 30 minutes! We will crate later but we made him a play-pen similar to the one his breeder had set up in our living room... We feed him in it so he's used to being in a confined space that is comforting... toys, blankets, and a nice bed. We gradually leave him alone in short but longer increments so he knows we return before too long. The first year is the most work, but its worth it! I hope this helped!! Enjoy your new baby!! 🤗 P.S. we noticed at night once a week, I give him a warm massage/bath and he is out cold!
