Somebody needs attention

When Topaz was little, he would fling himself at me. He would fling himself at the other dogs, especially Tiger Lily. She's so big it wasn't a problem...when he weighed a couple of pounds it wasn't a real problem even for the other Cockers. They didn't like it, but nobody got hurt. Now, he weighs 22 pounds and is bigger than the smaller female and still throws himself at their heads. It irritates everybody. And I'm sure it doesn't feel good. He does it especially when I'm paying attention to somebody else. The others try to get attention by butting in too, but his rocket-launcher approach is a little unsettling. Definitely destroys the peace.
