My cocker spaniel is just about to turn 1 year old. He started being very aggressive a few days ago. He paws at me and starts barking and biting for no reason.
Does anyone know why he should do this and what can I do about it?
Your dog is trying it on and as he learns he can get away with it he will do it all the more. This behaviour needs to be nipped in the bud - quickly. There are too many dogs that end up in the pound, or worse, because of aggression problems that could have, and should have, been addressed much earlier.
Apart from that, he could cause serious injury one day.
I agree with Steven, go back to basics and teach your puppy obedience commands. Don't let him get away with not following your command as this will only teach him that he doesn't have to do as he's told.
If you can't handle it yourself, easily, call in the big boys and get it sorted - pronto.
Good luck.

You're right to be worried about this behaviour as it's not normal and is unacceptable.
It sounds like your dog is attention seeking and being just donwright naughty! There's plenty of help available on the internet (and also on this site) to help you train your dog. I would go back to basics and make sure he's corrected each time he misbehaves.
If you can't get him to stop relatively soon, I would recommend that you seek advice from either your vet or a canine expert.
