LOL, No pictures.. You want the frame before the bulk, the parentage says you'll have a nice size pooch.. That weight at 7 weeks is fine, our 5 mo pup is no heavy weight but extremely athletic.. Babies loose weight when they come home from the hospital before bouncing back, change, stress has its hand.. Your going to need TOYS, and or you might find yourself a toy, chew toy that is.. Have a toy in hand, you'll thank me later.. LOL.. Say what you mean and mean what you say, playtime as much as you can give.. Fabric frisbees are the bomb, water bottles are near free maybe you need new socks , most anything works.. Feed sparingly, pups shouldn't walk away with a bloated belly.. Use food to get the 1st commands underway like sit, down, wait.. Watch this, and more of them..
