Very adorable.

The halti was the only thing that helped my sister get hers to walk managably. Starting at 5 months or so and going to 10 instead of walking he'd chomp on his leash and pull you, even though prior to this he would walk perfectly and had completed obedience training. It did wonders for them and they don't even need it anymore (so that is a point against the trainers - their obedience school trainer told them it would take them 4 years of very firm training to get him to calm down for walks when they took him back. It did take him about a month to no fuss put it on though. It probably would have helped my Dads because he just strangles himself on a choke chain, but now thats he's 7 he's naturally calmed down.
