Living with big dogs can be a challange. I had an Afghan that stole a pizza off the top of the refridgerator once. I had weighted it with a cast iron skillet but he got it anyway.. He also got a couple of cheesecakes I had cooling on the stove. Raider was silver and black, everyone thought he was named for the football team, until they looked away for a second.Our Great Dane licks the feeder clean at every opportunity. We have to keep the door closed, she can aways reach them otherwise.
