Hi Stephen, her mum is a black and tan show cocker.
Maisie will just be playing nicely with her toy and then discover that my hand is much more tasty to chew and will start chewing and biting me. I try to push her away with a harsh NO but she then starts to growl and bites me even more!! Her eyes don't look any different i don't think but he does seem to get very mad. Last night i put her in her pen for 'time out' and she quietened down within a couple of minutes and then licked my face as if to apologise.
OK - That sounds good - as the more severe version (hence my questions) could have been linked to "Rage Syndrome" - I say "could" as it is in itself rare - though none the less it does exist.
One suggestion (and it is only a suggestion - but it works for us and those that have chosen to use it) - is to put your hands around her muzzle (around her mouth keeping it closed) and gently squeeze until she pulls away - a more assertive pup will come back at you so do it again slightly harder - and again if need be - it is something YOU must win.
Dogs are pack animals and even when "play" fighting in their own litter they are actually working our who is top dog and what the pecking order is. Basically it is not a game to them - it is a way of working out their social structure.
If you bring a puppy who is dominant into your home and if it thinks it needs to be above You / your partner and mostly kids - it needs to be shown that it is the lowest in the pecking order.
A more dominant pup will take on a more assertive role within your household and as such will worry more; be more aggressive and snappy - it thinks it should be "looking after" You not the other way around.
If you observe dogs socially and if you watched pups with Mum when little - you will see Mum "correct" pups if they get too much - normally with a deep growl and "snap" at them - they soon learn and back down - this is effectively what YOU have to do - you need to show your puppy that YOU are in fact a bigger more aggressive dog - and YOU do not like the game they are playing - so YOU need to give the short sharp shock dominant barked "NO !" at them.
It is the same principle as having something loud to shake at them.
Some people say that they dare not hurt - or cannot get hold of the pup around the mouth - but it is worth a try - You must keep you pup on the bottom of the pile "pack-wise" - as that is where it will be most happiest. xx
