I'm sure, that's a tough test for any individual dog of any type.
So now my question is to the ETHD board. Is there anyone out there that has a specific breed of dog that has the tools to do this type of task with the things that she described in the terrain she described and produces that in is offspring? Something that you personally own and use.. no rumors.
First off I don't hunt swamps, but hunt where I don't want a race, some of my country is real rough with no vehicle access or has a couple hundred foot cliff edge.
There are several people working on and producing dogs of this type, I happen to have a couple. But I often use a team of dogs for this type of work and that team will vary a bit in composition. There is not really any question that this type of dog exists and can be reproduced.
The test, so to speak, is not that tough believe it or not.
