when I got my bulldog I had a similar issue, it would "click" when I pressed the start button, I could feel the starter making the "click" when I would put my hand on the starter as I pressed the start button, if you can pinpoint what area the the click is coming from for sure, you might get a better idea of what's wrong. My issue was a broken starter gear that had shattered and broke a chunk of the starter housing and jammed everything completely up, but would allow just enough movement to make a little click noise

Double check your wires going to the starter and battery and make sure everything's tight and connected properly, sometimes you over look the little stuff without realizing the first go around. A multimeter would help to see if you're getting power to the starter if you have one. easy way to figure out if you've got a starter issue or no power.
