Don,
We bought it from Agway, and as I have read in other TBN forums here they raise them in cages like chickens then capture the runoff. Not a pleasant task but the stuff sells for $10 a pint or so, so to those that elect this business they earn their keep.
What turned me off to this method was the bottle got tipped over in the garage, soaked the pine boards and the bench, still leaves a nice aroma on the right day..
Rancar,
Dogs are good, and they are effective, as a local fellow had coyote coming in and killing sheep, got a few dogs, showed them the area to protect, they marked the territory and no more problems. I beleive this is the basis for deer control as dogs mark the territory and deer don't enter, as from my experience deer are feeding between 4-7 AM typically in this area, and dogs are either inside the house or in their dog house.
We don't have a dog right now, had labs for 30 yrs, great dogs and when we can spend more time with them then we will have another.
