re: Vizsla

Nope. I agree I'm no Visla expert. Have experienced the same with 2 Weims also though. Seen 2 Vislas, a Weim, 2 Standard Poodles, GSP's and Boykins at our Hunt Tests. The GSP and Boykins were good little markers. The Vislas and Weims didn't trust their eyes and wanted to use that great nose to their detriment. I still don't know why the poodles were even there.
It all depends on what you want the animal for. I need a dog that has a good nose, and great eyes, who will dive off in subfreezing water and take a 45 deg hand signal and hold it crossing two levees and 3 rice fields untill it finds the cripple goose. Or handle off a dead duck in the decoys to chase down the cripple in the brush. Thats our game. The pointers/setters are good at what they do, find and flush. Just depends on what you do with them. I've seen good marking pointers, and I've seen good pointing/flushing labs. If I ever move to grouse/pheasant country, I'd like to have an Irish setter. I've always loved those dogs.
