me and my boyfriend own a very sweet lab. he does really well around our friends and their children. we recently got a older roommate. when we first met her things were good. she seemed very nice but the day she moved in we kept the dog in our room so that they can move the stuff in and out without having to close the door. when i got home from work (my boyfriend was home but outside) i put him on his leash and brought him out. he did well with everyone coming in and out. he let everyone pet him. he was very "happy go lucky." i took him on his walk and brought him home. the people were getting ready to leave so i took him inside to feed him and i went back out to see if my boyfriend needed anything. the lady walked into the house and a minute later i heard her yell my name. i ran inside she said my dog attacked her. i didn't know what to think or what to do. she lifted up her shirt and there was a little mark about the size of a pea. i asked what happened she said she walked in thinking i was inside and the dog looked up at her and growled. she talked said hi to him and try to talk to him at the same time she took a step towards him. i didn't hear the dog bark. i don't know what to do the dog is like my kid. p.s. i'm not even sure if i'm posting on or the right thread.
