Here's the scoop. I have a huge backyard with two 4month old great danes in it. They pretty much live by the back door most of the time when they're not roaming. I feed them pretty well with top of the line large breed puppy food. BUT, the stinkin' birds just won't stay away from the food no matter what I do. I put it right next to the house and they just wait til' I close the door to swoop in. My dogs don't care to share either,lol. How do I deal with these pesky birds?
