Since out son died 8 weeks ago Coco has been getting worse with her barking. It seems to mainly be when someone goes past the house or makes a noise outside. She has also started jumping up, something she's never done before, she's also been getting a bit anti social when walking. I always walked her till I broke my back in November when our son took over, he died in January so I guess she's having a lot to deal with but we don't know how to stop it. Any advise will be appreciated. Than you.
