Why should they come to you when there's so much better stuff around to do?
If you want them to come to you
make it in there better interest for them to do so
Always have a bag of treats handy for them
and you can set up training exercises where you call them from across the room with the help of someone else
have the other person release them
and call them with a treat they can see
do this from time to time
so they will get the idea that when you call good things happen
Be careful that you don't get them used to hearing their name at ever increasing Octives .............
