Nittany and Blitz are both vizslas. I've never seen a weim hunt, so I can't compare them. Most vizslas are medium range working dogs but there are some field trial lines that will run bigger. Vizslas are called velcro dogs because they need to be part of the family. They will lay on you when they are not running around. Vizslas don't make good dogs if you plan to keep them in an outside kennel. They need to be part of the family. They are a great breed but they aren't for everybody.
