Blood Trailing K9 - a successful find begins with a consistent start routine
When blood trailing lost deer with a K9 the success of the find is a result of a consistent start routine, a consistent start routine outlined here will return the best chances of finding your deer.
The check command: This is a indication given by the handler to what and where the dog will start its trailing. Training begins at home with teaching the dog to scent check what you are pointing to, typically done by placing a piece of food under the dogs toy and bringing your hand close to the toy while at the same time giving a verbal command to 'check'.
The scent inventory: While removing the dog from the vehicle give the command to start work, make this command with added excitement to encourage drive, do this a few times and the dog will learn its going to do the job it likes. The dog is then walked on a short lead to the start of the blood trail. While on the short lead walk the dog in a full 360 degree circle around the start of the blood trail. All people who will be following you behind the dog should be present at this stage. The diameter of the circle will depend on the terrain but will typically be about thirty feet, during the scent inventory watch for head pops, this indicates the dog is looking at the deer's direction of travel.
The start: Immediately after the scent inventory walk your dog back to the start point (center of the circle) where the blood trail starts. At this point remove the short lead, harness the dog quickly with a 30' lead, and give the verbal check command at the same time bring your hand close to the deer blood.
Now hang on to your dogs long lead for a ride.
Pro tip: make sure the lead is not wrapped around your legs otherwise you may go for a tumble.
