The first week we moved here, coyotes came through and ate our neighbor's dachshund. I decided that I was going to make it safe for our dogs, no matter what the cost.
We had a side yard built with a stone front gate (to look like the Alamo) and a doggie door for the dogs to freely go in and out. Realizing that the new side yard was also deer proof, we planted several fruit trees (2 plums, 1 peach, 1 Asian pear, and one olive tree). We also have roses in pots.
