I'll toss in a few words here. I have a female and she'll be with me till she dies. I've also been around a some other Jagds a time or too. That being said, hunting terriers in general, and Jagds specifically, aren't for everyone. As a matter of fact, they are a perfect dog for a very select few and rotten for the rest. IMO, Curs and even Labs are a better "everymans" dog. You mentioned blood trailing and trapline work. I don't think you could keep a Jagd happy just doing those. On a trapline it will want to attack every critter in a trap. You can break it of this or you can just leave it in the truck but that goes against their instincts and makes jagds less than ideal for this work. They need hunted and hunted lots. If you don't they'll do it on their own.
Jagds look like the perfect breed on paper and the internet. And when it comes to a combination of grit and nose they are tops. But they do have drawbacks that are hard to describe on here. I bought into the hype about these dogs being a great "versatile" dog. Can they do a lot of different things, yes. Are they great or even good at most of em, no. At least not with a bunch of work. My suggestion is you find someone with Jagds and see how they hunt em. See how they work and do it more than once, twice, three times, etc. Unless you have been around the breed some you will not know what they can and can't do and you may have to adjust "your" hunting to "the Jagds" style. If I had to guess, I'd say 90% of Jagd owners use em for den dogs 90% of the time. Being and trail/tree dog guy that's been hard for me. Go see some in action and then decide. If you don't have access to some Jagds to see in action I wouldn't recommend one. They are, shall I say, unique. Know what your getting first.
BTW, mine is great in the house and cats are vermin to her, my feist and me.
