Just for reference I wanted to let everyone know (in case you don't already) that collars like prong and choke are NOT to be substituted for every day collars! They are for training ONLY! I was watching animal cops and this lady adopted a rescued doberman who had a collar embeded two inches into its neck on one side. After she was all better, they showed her at her new house, and her mom had a choke collar on her with tags for an every day collar!! Ahhhh!! Especially considering her background you'd think that you wouldn't DO that!! So please guys just keep that in mind. I know this is slightly off-topic but I just wanted to throw this warning out so everyone knows!
