Hi,
I have a one year female Rodasian Ridgeback. I am facing similar problems like what you are facing but even worse. She is totally disobedient. she is always jumping on us, biting and pulling our sleeves ( mine and the kids) to attract attention for playing. she takes our stuff ( not her toys ) like the remote control, mobile phones, shoes and runs around ,again I think to attract attention. steels food from counter . she barks back when given any commands and refuses to obey, though I am sure she understands perfectly well. She might obey finally but after a lot of repetition. she does all that in a playful manner but she is a big dog, so she is very annoying and sometimes painful and gets on everybody's nerves. The kids are starting not to like her because of that behaviour and therefore I tie her with the leash or put her in a separate room till they sleep and then let her loose. I feel sorry for her but she is really totally out of control. she only obeys my husband and again not immediatly. I think she needs to understand that we are the alphas and I tried applying the sitstayfetch technique which worked for a while but she is now definetly getting a lot worse. Please help me with any suggestions.Thanks
