Nothing n Texas except cats, big cats, or feral dogs. I have pepper gas for Fideaux. Lions ain't hard to kill or deter if you see 'em coming, but I never hear of attacks outside Big Bend basin this winter. There are cats all around south and west Texas, but they don't worry me.
SO, my general outdoor gun, the one I carry "on the trail", actually, I'm usually "in the boat", is a .22. I carry it in a pocket concealed or can belt carry. My favorite to carry if I don't have to pocket the gun is a Rossi M511 Sportsman .22 revolver. Stainless, has been fired more'n I can count, would have to use scientific notation, likely. It's 1" at 25 yards accurate and I shoot it VERY well off hand. It has brought home the bunnies for me, shot snakes, great trail gun.
I had been using a Phoenix Arms HP22 for a pocket carry, but it's been problematic wearing out parts and such. I don't even shoot it that much, but it's accurate as all get out, 3" at 25 yards accurate, and pocketable. However, I've replaced it (still have it, just don't pay it any mind anymore) with a new Ruger SR22. The Ruger puts Federal bulk into 2" at 25 yards off the bench. It's lighter than the HP22, also, though a little larger. I've not carried it afield, yet, got about 1400 range rounds through it so far.
If I'm in Big Bend, I conceal a 4" 357 magnum in a fanny pack. I worry about the coyotes and mules out there, the two legged ones, and want something with some range that I can conceal and be legal with. I ain't worried about the wildlife. Usually a 3" .38 J frame type gun, actually a Rossi, in New Mexico as I don't think it takes a .357 to be safe up there, just want something just in case. The Rossi is light and easy to carry and 2" at 25 yards accurate.
