German shepherd,weimaraner American foxhound mix. What traits to expect?

I have a 20,000 sq feet of fenced land and a German shepherd and a beagle living on it. Just did some research on weimaraner and American foxhound and they are hunting dogs that like to sniff a lot. What should I expect? I can walk all my dogs 1 miles a day, sometimes 5 or 10 mile on the weekends
