I just read all through everyone's comments before i watched the video and was expecting to see a nervy, snappy, dog, but then the video made me really sad. What a gorgeous puppy, and the way she is acting reminds me so much of our gorgeous Sweep. We have a baby gate on the kitchen door, but only so they cant go running up the hall and escape out of the front door if someone knocks, or run up the stairs unattended and start "collecting" things from the bedroom. This is exactly how she would act if anyone that she knew approached the gate, she looked excited and her barking was clearly saying "hello, I'm excited, are you coming over to play with me" - her little tail was wagging away and she was doing the cutesy play bows. Then when the young bow moved about from side to side with the paper in his hand she still looked as if she wanted to join in whatever was going on and she was still wagging her tail. An then eventually she gave up standing up at the gate, looked around at you as if she was wondering whether you were going to let her through the gate to play and then got down from the gate altogether and wandered away from it, I thought she was actually disappointed that she had thought she was going to have some fun and get played with and then the little boy didn't come through the gate and so she just gave up on the excited barking. It's an awful shame that the children are "nervous in case the pup bites them" - most children are so excited to have a puppy and even wind the dog up with giddy over-excited games. It would be really lovely for the children and the pup if you could have supervised calm play sessions with them, with everybody talking and behaving calmly and lots of treats for good behaviour, it will be a terrible shame if the children miss out on the pleasure of the dog growing up with them and becomming devoted to them, as cocker spaniels do with thier oweners. Good luck.
