We have recently aquired a rescued GSD to add to our dog family and have many problems that l am working on. One really irritating problem is that when she is in the car and is nearing our destination to a favourite walk she is doing the yelpy excited bark and nothing will make her shut up. Also everytime we turn back into our road coming back home - she starts yelping and will not stop then either - the other dogs are fine. I know its excitement but lve tried shushing her but she won't listen to me at all. We literally announce our arrival into the street so causing a bit of constination to the neighbors not forgetting our hearing. Any help would be appreciated.
