Ha ha I tell you as far as pests in the garden go, no desirable plant deters squirrels, rats, and other critters quite like my Chief. I also Companion plant my entire garden... Totally pest, and Pesticide free...
I gotta keep chief happy though so I plant a but of things just for Chief. He picks his own lemongrass and strawberries. I feed him carrots, peas, blueberries, apricots, bananas, and anything in season that is healthy for dogs.
What do you plant for your dog? Pictures?
