I'm with JW either a German Drahthaar or German Shorthair. Pretty much the same dog, different fur. The Shorthair is a little easier to clean up after a hunt. Pointing is in their genes, it doesn't usually take much training to get them to point. A while back I was exercising my daughters Shorthair, he stopped and pointed at a bush in a city park. I thought there was a Rabbit in there, when I gave him the OK he dove in and came out with a Cock Pheasant in his mouth and brought it to me. This is basically a family dog and never had any training that I know of.

Like Oldtimr said, most hunters discourage their dogs from chasing Deer. And sometimes it can be one of the harder lessons for the dog to learn. They have many thousands of years of heredity that tells them to flush and chase Deer.

Dogging Deer is a good way to get a dog seriously hurt. They can get so fixated they run right through a barbed wire fence. Or chase the Deer across a highway or just run them until either the dog or the Deer drops. They can run a long long ways. I had an Ibizan Hound that had a major Heart attack chasing Hare. A good German Drahthaar or Shorthair can cost a substantial amount as a puppy. You add in all the time for training and you have a substantial investment in that dog.

Teaching a dog to point and flush without the chase IMO could be tricky.

Best guess is mankind and dogs have been hunting together for around 120,000 generations. Not all people are dog people, but the hereditary tendency to be a team almost has to be at the gene level for many humans and most dogs. There is even evidence that Neanderthal man kept Dogs.

Something to consider is what kind of coat the Dog has, a single coat works better in hot climates. A single coat and thick skin may be OK, a single coat, thin skin and jumping into a thicket can cause a lot of damage.

Best Deer Dog I ever had was a Shepard Boxer mix. She had a strong herding instinct, she would turn them and run them back to me. She had short hair for the hot south. And had outstanding stamina. That Dog could run forever. Just a magic mix of genes, it happens sometimes. She was almost pure speed dog, but could last a lot longer than most speed hounds do. She was almost equally sight, nose dominant.
