We've got a dog like that.
I used to be able to get thru a spot in my old fence, but the mean ol' neighbor complained. I really didn't mean to scare his little girls ... I just wanted to play with them. One is big, and the other is about my size. They're very sweet, but when I barked " HI! " and gave them my best happy smile, they ran into their house! I was a little sad, because little people give the best tummy-rubs. And they're dependable ... I don't think the big people give enough tummy-rubs, and they seem awfully busy.
