If they are wild birds, keep the dog food INSIDE. they should not bother the pool, though.
If you have fruits or vegetables that are attracting the birds, it may be best to remove those items from your home or property that is experiencing the bird problem. Anything else that you think may be attracting the birds, you might also consider removing or doing away with. Those are the most humane options. You certainly don't want to go into options that would harm the birds. There are a few ways you can humanely get rid of your bird problem. There are visual deterrents, and because birds get frightened pretty easily, the birds will stay away. Also there are physical deterrents that can keep the birds away. Bird spikes are a good example of one of these. Also there are taste aversions that keep the birds from eating what you put it on.
