Stitch is a yellow lab, and he lives next door. Seems as the weather gets warmer, his owners put him outside in their yard, earlier and longer. Last summer, I had to ask his owner to move Stitch's dog house away from our mutual fence as he was standing with his paws on the top of the six foot fence, peeking over at my Yorkies.
The neighbors pulled Stitch's dog house up to their house, about eight feet away from the fence. So, Stitch is still able to get ontop of his dog house and peek onto our patio, though I do not believe he can jump the fence from there.
Below is what I wake up to most weekends when I'm trying to get in a few extra zzz's. Stitch, howling away!
