Behaviour started around 3 years old.
No children in house or garden but there is a play area in veiw which sometimes he barks at but not always, he used to moan as he wanted to be out with the children.
He is on a lead when walking along streets but not when in the fields.
Obediance traing we went to puppy training, he heels at your side with or without lead, sits at pavements until you say ok, generally comes back when told unless bitch in season or a dog that smells same. He sits, down and stays until told otherwise.
He growls when you stroke him at certain times but you know this is going to happen because his head changes and the hair on his neck stands up, this is more with my son usually going to work or going out and occasionally with me going to work but not in general, he usually loves being stroked and rolls over for.
When someone knocks at the door wheather he knows them or not he barks until you open it then he is there best friend he is all over them and if they are coming in to stay he pesters for quite a while before he gets a toy and sits down with it.
