the other day i noticed i had a heifer (500 lb range) thats was just laying around on her side. went out made her get up she was favoring one of he front legs pretty good i watched her for some time she could walk an try to put weight on it but moved off with a limp i shrugged it of as maybe twisted joint or something. went checked on her today now her front leg looks good but her hind leg on the same side is swelled up what looks from the hip all the way down to the hock i was able to get my hand on her it fills as if she has fluid right under her skin i gave her a shot of al 200 do y'all have any ideals or suggestions on whats going on thanks
