holy cow.. what is a javelina? (great biologist I am huh & too lazy to google)
some type of wild pig? how big are they - like in relationship to a standard poodle? or german shepherd?
are they like deer in that they get comfortable (and wont hurt) people after time around the yards & homes?
Dolly, here is a link by the AZ Game and Fish Dept. It will tell you all you would care to know about the javelina (including size - 40 to 60 lbs.):
