Dog owners really bug mee somtimes. as far as im concerned you shold never let anyone toch your dog and if you do insist on letting people toch them you must always hold them firly buy the collor so that there is no chance of them even bitting somone.
No matter how well anyone thinks they have there dog trainned at the end of the day its still gunna do what ever the hell it wants to do.
keep the dog and dont let anyone toch it.
