Ok - we've just got a labradoodle and he is lovely. But we took him to our new vet last night for his 2nd injections and the first thing the vet said is that from his position etc on the table, he was trying to be very dominant. He asked about mouthing, nipping, body checks, whining, barking etc and how we were dealing with it. Well, tbh, we had a professional puppy trainer in on Sunday, just 2 days after we collected Percy and I understood that all of these things were normal puppy behaviour and we were given, I thought, good techniques for dealing with them by positive reinforcement. For example ignoring all barking and whining. Ignoring excited jumping up, only give attention when all 4 paws on the ground, tell him he is a good boy when he is lying quietly, tips to put food in bowl whilst he is eating to avoid any future food aggression and distracting him from chewing and nipping by providing alternative toys and by using a water pistol to distract him from things he shouldn't be doing. The water pistol is just a little squirt, he mustnt see where it has come from but just interrupt his behaviour. The other thing he said to do with nipping is to place hands around neck to form a necklace and prevent him from moving head to nip/bite and if necessary, force to the floor.
I've been doing loads of research today and feel really confused now because some trainers advocate this; some don't. I have 3 children (DS 11; DD 7 and DD 4 months). The 7 year old is fast becoming quite scared because Percy really goes for her feet and hands and mounting (dominance). DD 4 months is obviously kept well away (or rather he is from her) and DS 11 doing loads of the training with me and is really becoming 2nd in the pack, so to speak.
So, my question is, does anyone have any really good tips, other than those mentioned above, for dealing with the nipping in particular? Also, what are thoughts on the "submission" method for when he has nipped too hard or aggressively? And also, how do we really know whether he is being dominant or just doing the puppy teething thing?
Finally - how long does it typically take for them to get the gist of "I'm the leader of the pack"... yeah, I know, how long is a piece of string!
Yours confusedly and hoping for some advice.
