Dominant puppy

We have a nine week old collie puppy which we brought home last week from a reputable show breeder. As the week has developed she is demonstrating more and more dominant behaviour and it's becoming a problem as her biting gets harder and she is jumping up at faces.On a couple of occasions she has growled and tried to bite. It seems the worse behaviour is on the evening when I think she is just having trouble winding down so we have put her in her crate with a chew toy. If we use the standard ouch when she bites it makes her more excited and she becomes more frenzied and bites more, then constantly jumps on the sofa. When we tell her to get down she ignores us, lift her down and she just jumps straight back up and on and on it goes with her biting getting more excitable.
We play games such as hide the treats and have started training from day 1 with socialisation, car journeys etc. She is feed on a high quality dried dog food four times a day and any unwanted food is taken up. She never rushes through doors before us and at times is very sweet but the biting is driving me nuts. Someone suggested squinting water but she loves that, loud claps don't bother her Has anyone got any other suggestions. Incidentally this isn't our first border collie so we are not novices but never had such a head strong one before.
Still love her to bits but want to iron out any unwanted behaviour asap
Thanks for any suggestions

All puppies bite and some are more excitable than others. I'd put her on a lead in the lounge and sit on the floor, that way she's less likely. to jump on the sofa and if she does you use the lead to get her down. I find shoving something else in their mouth works well too

Thanks for your reply. I really, really appreciate it We do tend to sit on the floor with her more than the sofa and have tried giving her toys and chews but she soon reverts back to biting. I haven't tried the lead yet as she had such an extreme reaction to her collar that I was delaying it for a few more days. She has just returned from the garden and when my daughter tried to stop her digging to bring her in she started snacking at her and squirming and lunging round when she picked her up. She can be lovely but this behaviour appears to be escalating . I have twin granddaughters who visit and at the moment they are frightened of her

Just sounds like normal behaviour to me. Not ideal but par for the course.

One of those jiffy lemons (washed out) can help. A wee squirt just to interupt unwanted behaviour followed by a treat for responding positively.

This could be food related. Poor puppy, she is very young and very unsure of things.

If she reacts to the collar then I would try a harness. Tbh all my puppies are walked on a harness although they wear a collar.

please don`t use water sprays or any negative corrections on your pup, she is 9 weeks old, and a baby she is displaying all normal puppy behaviour, its also worth understanding she is not being dominant either, some pups are more manic that others, but what she is doing is playing and seeking attention, albeit in a way you don`t like, my boy was the same, his teeth were a flipping nightmare.

You need to find a way to give time outs, if sitting on the floor makes her bite then its not the way to go, when she is getting to much remove her from the room, put her in her crate (if you use one) with a chew /toy and allow her to settle, some advice when they bite and become OTT is to make a high pitched squeal , turn your back and so on, none of that worked for us, it might work for you, so you have to find what does work for you, for me the only way to stop a whirlwind of a biting pup was to remove ourselves from him, by leaving the room, this way he is not getting that self rewarding attention.

I think you are expecting to much from a 9 week old pup to be honest, she is going to mouth, she is not going to just accept a collar and lead /harness straightway. you are going to have to introduce all these slowly, start with her having wearing a collar in the house, introduce a lead to it, pick the lead up and follow her around, using lots of praise and treats........

Have you spoken to your breeder, she will be the best first port of call for advice with your pup, after all she will know her lines and temperaments of her dogs.

Thanks for all your help. Today things have improved she has been good and not as excitable��. We have been out socialising and she let people pat her in my arms.our little training sessions are going so well as she is very bright. I agree Jackie ,water squirts and ouch don't work, but I think walking away from her does.
One unfortunate incident though. She found a small piece of plastic which must of blown into the garden and was running around the with it. I didn't chase her as this is just heaven to a collie so I waited until she calmed and approached her so she could see me. When I tried to take it off her she snarled viciously and bit me drawing blood��
Any ideas on the best tactic for this behaviour as it would of been dangerous for her to chew plastic.
Many thanks

Oh dear, she's being an obnoxious little madem throwing a strop not wanting to give up her prize

You could teach her " swap" this will come in useful for the future with anything you want her to give up.

When she has something you don't want her to have then. Get her to swap it for a better valued object, a tasty treat... Add a command also as you swap objects.... Drop... Swap, wht ever suits you best, if she's going to snap and growl when you want her to give stuff up, it's best to get this in place now,

Puppies throw tantrums and test boundaries, you just have to find a way that works best for you.

Thanks Jackie I will try.I hope my comments don't sound negative about her because she is lovely, very intelligent and a quick learner. She is like an angel �� one minute then is like a thug the next �� lol.
