In tracking big game there are two options .
You have the search after a good shot , where the deer/boar runs 60/80/100 meters ( maybe in cover or woodland ) collapses and dies . For this about any gundogbreed must be trainable . Also the clumber from our forum member Ash will be perfectly capable of doing this .
Than you have the badly placed shot on a maybe strong stag or boar , which is just behind the vital organs or breaks a leg . Everybody will be able to immagine a situation where the deer can go far , very far . Let's make the situation a bit more complicated . There is about 10 - 12 inch of snow or long heather or strong bracken . When you tracked this beast for 2 or 3 miles it goes of when it sees you and still runs for about another mile and you need the dog to chase the annimal , bay it and pull it down .
This is another ball game .
This is where the " german " dogs become strong . They are big enough to go over snow , heather or bracken . They are naturaly loud so that you can hear where the beast and your dog go to and they are " sharp " enough to pull down a large annimal . A teckel is a nice dog . I owned one about ten years ago , but isn't capable of dealing with this second situation . The clumber might not have the pace neither the sharpness for it . A labrador will be able to do many things , but will not be loud and will miss some sharpness . It's horses for courses .
The Bavarian , Hannover , Wirehaired pointer , Shorthaired pointer , Kopov , Dachsbracke , Wachtehund ..... will be able to do this .
If I would put my time in training a tracking dog I would like to be prepared for both situations . What about you ?
