if i may, here are a few pointers that will really help you and your dog- some are things i have learnt along the way nwith the varied dog training i have done- others are things that i have learnt from other trainers.
1.you have a really good "stop" on your dog- well done- thats always the first step- dogs need to learn to stop before they can go- and yours is good for a pup of that age- in fact for any dog. i like to use a lie down- but the sit is just as good. its a command that throws the dogs body, and in turn his brain out of gear- can be used to rectify or diffuse. dont use it on a trail- unless absolutely neccesary- as it can disengage them
2. you have a nice long tracking lead- looks about right a good 35' is good. now only use that tracking lead and collar/ harness when you are tracking- NOT for anything else- he will very quickly make the association , and know its work time- and engage his work brain!
3.you have the right idea about making your dog check the arrow etc- but here is an idea that works really well- taught to me by a top tracker.bring your dog close to the area. and tie him up maybe 10' away or so- go over to the trail head- and fuss around there- i usually get a stick- poke at things- look around- this is whats going to happen in real life as you examine the shot site- before letting the dog tramp all over it- you get to look at the blood- ascertain the type of shot , direction etc etc. this is all valuable and realistic- but also gets huis attention "hey, whats dad doing over there"
i then go over - pick my dog up ( easy with my teckel!!
) and carry him to the trail head and put him down on the trail- you are trying to take him from his tie up point to the trail head - with NO other distractions on the way- you may be able to do it with a bigger dog- on a short lead- holding his head up- so that he cant start scenting the ground,and get any ideas, and jump the gun before he gets to the trail head.
4. now control on the trail. i mark the trail with little bits of flagging tape or toilet paper- so you know exactly where it is. if he slips off the trail- let him hunt for it and find it again- if he is off- and heading away- dont call and distract him DO NOT pull on him. he will learn to resent that- and now its your idea- your thought- you want him to think for himself and to work things out himself- he needs to be able to figger things out when only he can smell the trail and you cant see it.just take the slack out of the line and brace it against your body. become like a post- he will pull up against the line- and try a few times- just be solid!!! he will realize that that is not working, and then go back in the direction he came from- then you can help or encourage and call him over back to the trail.- so the key is- when hes working- line super loose , not tangled, and when he gets distracted or badly off course you become the silent strong post!!
5. then the reward at the end of the trail- a deer leg, a piece of hide- something for him to take home and to worry.
6.marking the trail. i didnt see what you do- but this is what i do. i use a walking stick and tape or ose clamp a deers leg to it- i dont walk on the trail that i am marking- i walk as far away as i can to the side- otherwise he will just end up following your trail making a deer trail-with odd drops of blood or blood mix on the trail itself- and along the way i will make a few"beds" with lots of deer activity and more blood, and a few small pieces of meat- simulating clotted blood etc- allow him to eat them on the way if he wants.
initial trails very easy- no tight turns- dont take him past distractions- make them easy- DO NOT set your dog up to fail- set him up to succede. there will be lots of time to challenge himn- as he gets the hang of things then you can start to make the trails longer and more complicated with dead ends etc. when he loves the game as much as you do - and loves the challenge then up it a bit.
generally speaking- if he is atrting to go too fast- then its too easy- then you can up it a bit. the blood more dilute- 10 or 15 to one less blood - one drop every 10' or so. eventually you want to get him off the blood- and be only tracking the trail you put him on- as you are not tracking a blood trail but a wounded animal rather. they will track the cortisol that is released from the interdigital glands when the animal is stressed.
you and your dog are doing really well- maybe just try the on trail control and the trail head stuff, and see if that helps a bit.
good luck, tracking dogs are awesome!!!
yours looks great- and what i really like about him is that he is calm and collected on the trail- and really wants to please you- those are things that have to be in the dog.
well done!!
