I have a lab x collie (and think part German Shepard!- he a right mut! Bless him) he has been my baby for the past 6 years but he is incredibly hard work, very bonkers and jumpers up people, barks and snarls at strangers (we have to work really hard with him every time we have people round! Using positive reinforcement and proximity training), barks at what feels like fresh air when outside (i.e when we are entertaining guests) or barks at car doors, people walking past the house, postman etcwe have previously had him with children and he has been OK following "introduction"and keeping him behind a stair gate, we now have a newborn of our own and worked hard the last few months to train him to be more acceptable of people (again positive reinforcement and proximity training)- but we don't seem to be getting anywhere fast, seen some improvement but it's not consistent which makes me unpredictable!, we have given him baby scents etc now our little girl is home and he barks at her when she cries, I find it a lot of anxiety to be home alone with my newborn in case he jumps up at me when I have her and I worry in case he runs into the room while she is on her play mat (he only has one speed and it's fast!) - my husband has suggested rehoming him and this absolutely breaks my heart (I've always said a dog is family not just temporary) but now I'm finding it a possible solution to get me through my maternity leave with less anxiety!! - has any one got any advice or been in similar situations? Many thanks,
