I worked for a wheat and sheep farmer many years ago. Had to lay 1080 baits for rabbits on many occasions. Used a specially built trailer with a 44 gal drum rigged to roll on the top of the tyres. As it did so, every time the little adjustable door came around, it would drop a couple of carrot chunks into the furrow left by a single disc plow mounted on the front of the trailer. A log or something dragged along behind did a good enough job of burying the chunks. One or two "free feeds" then do another run with treated carrots.
This tactic usually resulted in a better "kill" as the rabbits were now less timid and used to the free feed.
Anyway, there's a couple of points here. When handling the gear/treated carrots, we had to tie up the farm dogs and stay away from them. An innocuous lick of the hand or clothes could bring disaster, that's how deadly the stuff is. I've been told it's not deadly to humans, but I aint trying it.
The second point is the use of a furrow to lay the baits. Now I haven't laid "dog" baits, but I'd suggest this may be the preferred method. The reason being, usually people who see these flattened out single furrows, rightfully conclude the association with "Baits", especially where there are 1080 signs around.
I say this is the preferred method, as it relies to the dogs sense of smell to find the bait and not his eyesight, or for that matter, the eyesight of birds, hawks and other native animals.
I remember foxes used to get nailed, as they fed on the rabbit carcasses. Unfortunately magpies, crows etc used to cop it as well. Potentially, your dog also. Good operators, farmers etc, would go around every day or two to pick up carcasses to limit "collateral damage".
Back when Fox skins were fetching up to $35 each, some guys were baiting specifically for foxes. These guys would simply go around the next day and pick up the dead foxes. Baited animals rarely moved far. I'm told a good skin buyer could tell. I believe it results in hair slip (loss) on the pelt.
This all happened some 40 years ago when I lived in Horsham Vic. so that's about as good as I can recollect.
My thought's,, minimum, go for a good muzzle and stay away from single furrow plow marks which seem to go willy nilly around the place. If your dog is a "licker" and can get his tongue past the muzzle, be extra careful.
As far as rabbits go these days, Myxo and Calisi might be doing the bulk of the work, but baiting rabbits is still used I believe.
