Pumpkin Made Into a Boston Terrier "Rosco Killer Pumpkin" Is My Inspiration! Oct 29 2010 • By Pet Community 12 0 Community member Kirters is my hero for this creation of her pup, Rosco! Looks like I know what I'm gonna try to do this weekend . . . If you're creatively inclined, but not enough to sketch out the pattern for yourself, check out a bunch of dog breed stencils that I shared last year here.
