I have a 8 week old Lab mix the breed is a guess because she is a shelter pup I also have a 3 year old daughter and now that my puppy is getting familiar with all of us she does play rough with my daughter today she drew blood! I am a little out of my element here as to how to curb this behaviour. Please can someone tell me what I can do to make her be calmer with my daughter? She acts like my daughter is her litter mate she does nt do this to myself or my husband. Any help will be appreciated. I just want both parties to enjoy each other without hurting or being hurt.
