i need some input from some of you who have had to do this, the farm dog seems to have gone off to die im asumming this as she was at least 15 years old and has never been off the place in her life on foot or by vehicle either, my daughter, who is only 3 years older than the dog is beside herself as she has known this dog all her life,and wants her found to at least bury her, ive searched all over the place using other dogs who would recognize her sent with no luck as well as the neighbors pasture that borders ours, this old dog is fairly large probably 150 lbs or more and arthretic too, any idea how far a animal like that could go to hole up? i didnt think she could get off the place but apparently she can
