Hi all. I am a first time dog owner so have come here for some advice. I have a 12 week old beagle girl, did all my research before we got her and was very prepared. However, if she steals food and I try and take it off her she growls and bites me. Not just a nip but a hard, aggressive bite. Can anyone give me some advice on how to deal with this? And whether this is something I need to worry about as I have a 4year old daughter. Thanks in advance.
