Hi Jon, all the best with your new pup then!! After such a long gap, you're writing history (does one say so in english as well...? Never mind!); I'm looking foreward to see pics of your youngster then. Greetings from Switzerland, Cornelia
Sounds like he is a character. Sorry, I don't have any ideas. Just keep perservering with the toys and teaching him to learn the word "No" and he should respond to it, hopefully sooner rather than later. It is not as necessary to have a loud voice, but it needs to be a low deep voice, more like a growly sound... similar to how his mother or another dog would respond to him!
Glad to hear Charlie is doing well and starting to settle down.
Bridget is a little ratbag too! She loves to steal clothes and particularly socks (but we have been doing some tracking training with her with socks, so we can't really blame her!!!). She is just a delight to own. We love her to bits.
Our yard is doing very well and I attribute that to that fact that we had a sand pit put in when our boys (2 legged) were little and so now the dogs have it and they love to get in an dig in there, but they tend to leave the yard alone.
