It is a really good movie! I think it comes out on dvd july 19 or 20...
It's so funny how much your grandma's dog sounds like mine! Whiskers is the same way with peanut butter. For the first 6 months we had him I put his heartworm pills in peanut butter, but then i got this new kind of chewable meat-flavored heartworm pill and he wouldn't touch it. He just kept looking at me like "where's my peanut butter, lady?". So I had to slather this huge treat-sized pill with peanut butter, and then he scarfed it down. The worst part is the peanut butter gets all over his beard, and he hates letting me touch his beard so it's impossible to get out! Soooo stubborn!
