Hi,
We have a 2 yr old newf called Bosun and lately he's started to have massive tantrums, mostly in the evenings. He barks, growls, nips and slaps his paws on us, and generally isn't very nice. Its not just us he behaves like this for, sometimes he'll start on our guests too which isn't ideal! He can also be very naughty and unbelievably stubborn too, both of which i know are newfie traits! The thing is, when he's being well behaved, he is compliant, obedient and a joy to have around. But he really does seem to have a split personality and will not take no for an answer. He has a well maintained daily routine and swims weekly along with good walks. When he's having a tantrum we lead him out of the room into the kitchen that has a baby gate at the door, so the door is never shut and he can always see, hear and smell us. he normally settles down after this but sometimes he'll whinge for ages over the gate.
When i read about how gentle and docile newfs are I wonder if we've got the same breed!
I'd be most grateful for any advice on how to stop this behaviour as its exhausting and upsetting at times!

Sorry for not replying sooner- been a bit hectic !
Contrary to the image of Newfies -his behaviour is competely normal. Newfs love to play and when you add the stubborn streak this is what you get ! I am assuming he does this after his evening meal at some point (it is a raised blood sugar link) - and that you are feeding him twice a day (if not you should). The hand holding and pawing are absolute typical breed traits and how you respond is how the behaviour is escalated.He is only 2 - still a teenager. In order to channel this you must interact constructively, positively and calmly. When he starts off play tug games indoors, fetch outdoors and do training at the same time - stays will calm him and recalls burn off energy. never shout or punish - this will make it worse. Hand holding is the same - -fake extreme pain EVERY time and give him something different to do. Pawing means he wants stroking and attention - what's wrong with that ? !!
