I too had panics over the aggressive puppy biting stage and can assure you that it is normal for some cocker pups (hence the nickname cockerdiles). Bonnie was very aggressive; full on attacking, snarling, snapping and launching herself at my feet, arms, hands and even my face in full bite mode. I was genuinely scared of this little tiny creature and convinced she was nasty and aggressive. It is very worrying and hard to cope with if you have never experienced it before.
There are several posts on the puppy section regarding this behaviour. Have a read and it will put your mind at rest that it is not rage and is very common. There are loads of brilliant answers to the posts on the ways to help but mainly the best ways are regular time outs for pup, ignoring the behaviour and making sure pup has plenty of sleep as they seem worse if over tired.
Bonnie is now 15 months old and the sweetest, cuddliest mummy's girl you could ever imagine. She doesn't even growl at other dogs when they snap/bark never mind try to bite. She is currently sat trying to kiss me as I type this.....I would never have put my face anywhere near her as a pup. A lot of us on here have been in your shoes and all have beautiful sweet natured dogs once they have got through the biting stages xx
