Hi Keeper, yep, perfectly trained!!
If by perfectly trained you mean, ignore me and chase the other dogs, then yes

Max is great, he has great personality and I think will grow to be a gentle giant. He's stopped the puppy bitting and has his puppy training underway and is now towering over all the rest of the dogs in the class. Its amusing watching him with our Border Collie (who is 3 weeks younger) which makes him look a little slow on the uptake, I expect the BC will quickly take the alpha dog status with Max already following him around!
Funny thing is Max was the smallest of the litter and expected to grow to around 36kg. However he's now 21kg and tomorrow will be 4 months old to the day, and our vet is expecting him to grow closer to 50kg mark!
In regards to picking up bad habits from next doors barking dog, that has not been an issue as everyone suggested. We walk both dogs seperately at least once a day, most of the times twice, this is keeping them from being too destructive in the back yard (expect for parts of the poor lawn!) and they amuse themselves while we are at work.
Now if I can just to get him to listen to me more!
