I really need some advice. I have my 7 year old Jack Russell Terrier Jake, I got him a year ago from a rescue center and I love him dearly (He won the Veteran dog award today from his Rescue center for the over 7 years catagory! So proud of him!).

But, when I take him for walks. He pulls a lot, he gets snappy with other dogs and general just doesn't listen (He also gets terrible seperation anxiety when mum won't come on the walk or we go out the house!) Is this the usual or dogs or is there any sort of training I could get him? Any advice?

there is literally a thread about this right underneath yours here.
