Ok. He's only very young, and I think you are simply trying too many things and not being consistent enough.

I would suggest never using a rattle bottle or squirting water. Both are negative reinforcement, and your timing needs to be absolutely spot on. It also has the potential to make problems worse very quickly.

I would try the yelping and if yelping twice (be very high pitched and sound like a pup) doesn't work, then stand up and ignore him, if that doesn't work, leave the room. Wait outside for 10 seconds then come back in. Do not speak or say anything else. Make sure if he does stop biting when you yelp you say 'good boy' and play with him. You need to do this, and only this every time he bites. Every single time. 100% consistentcy.

DO ignore the barking, every single time you eventually tell him to be quiet, especially if it is longer all the time, you are just training him that he needs to bark for ages to get your attention.

Also, bear in mind extinction bursts. If your dog is doing something that previously got him attention (biting or barking) when the behaviour stops getting him the attention, he is going to try even harder to get attention.

This explains it quite well:

Nothing in Life is Free

As the other's have said it will only confuse your pup by trying different things,how long have you tried these things for before switching to another method?

We stuck to one method only it took a good few months but it paid off,you won't see results overnight it may take a good few months.

What I mean't was because this puppy is getting confused and your not sticking to one method you will have a puppy that you can't do anything with,totally out of control,with behaviour issues that later on may need rehoming,or a dog that bites a person or child due to not training correctly.

Tyler was a nightmare for biting,feet,hands,you name it,we replaced our hands feet etc with toys if he carried on,we stood up and totally ignored him,till he'd calmed down,the link Jackson posted is good.
Don't forget your puppy will also be teething and will need something to chew on.Kongs frozen are good.
Jackson's post above is also good advice again so is the link.

Totally agree with you, Duke was the same as Tyler and I handled him in much the same way as you did.

I tried to read Duke as there are times when a puppy will want to rest or have his own space that too has to be respected.

When Duke turned on me as a puppy I was lifting him from an area he shouldn't have been, to one that was okay and safe. He had other ideas.

This afternoon hubby got Duke over excited big time who got a telling off - hubby big time because I had to calm Duke down. SBT are hyper so it doesn't take much for things to get out of hand the rougher you play the rougher they become.

I think this is quite true for the terrier temperament. Our westie gets hyper even by just playing ball with him.

and once he gets over excited, starts nipping etc., stop the game. There is no time scale anyone can give you as to when your puppy will grow out of this stage. Some puppies are very quick to learn others choose to be a bit more defiant. You need to be consistant.

My dog can still get carried away at 3 years old. My point was that the rules I set when he was a puppy I still implement today if necessary.

I think terriers are the teenage rebels of the canines, like teenages you have to be one step ahead of the game.

Thankyou Sue. I am not expecting him to totally grow out of it. Just to calm down a little
