Keeping deer, rabbits, dogs, cats, and other four legged critters out of the garden can be a challenge. This simple method can keep many out:

Use wire fencing, at least 14 gauge (12 may be better), either twisted or welded wire, with a 2" X 4" grid. Lay it on the ground. You can cut it to fit around trees in an orchard. It can be laid on the ground right after you plant, or laid down before you set in transplants in your garden. Fold any sharp ends down so they don't create a hazard.

Animals don't like to walk on wire, and they'll avoid it if they can. They'll only walk on this if there are no other food sources around that are easier to get at. Worth a try if you are having animal issues in the garden.
