Cassie is 5 months old akita puppy and has been easy enough to house train we haven't had any accidents for ages but when people come round who she doesn't know well or has not seen before she wees on greeting them. My partner and i did not think was too much of a problem and that she would grow out of it but my mother seems to think that if its not stopped she will always do it. Shouting at her just upsets her and causes her to do it more so i just send her outside any advice would be great thanks
