I know eveyone has different ideas but :(.
I would not use a choke collar to prevent biting . All pups bite/mouthe when young . Th best way is to constantly tell "NO!!" when he does it and reward when he stops . If he takes no notice when you say NO , put him in his crate if you have one or go out of the room ( for a very short time only) and then re-enter . It will die down in time .
Could your pup still be teething - if so I dont think its nice to half strangle him :(
