Thank you all for all of the welcomes . I need some advice . Peanut is realy good with me and Russell . Last night i was playing with him on the bed and he was fliping upside down and rolling over on his back . Hanging from my fingers . We play like this all the time . Then a friend came by and as soon as he got into the room peanut reached out and bit me . What is this , just acting out of is it a behavor problem ? Does anyone know a way to correct this .
