How can I get my dog to stop barking when he is excited?

I have a 7 year old Jack Russel. Every time I bring him for a walk he screeches and barks at me out of excitement! He does this along with tugging on his lead for the first 5/7 minutes of the walk and then calms down…has he gone too old to be trained not to squeal like this?! Also, when he does this I do not give him any attention, but this does not deter his barking!
