We looked at Vizslas first, my mom loves them too but yeah they are way too hyper, her friends owned one and she spent a lot of time around it so she knew it wasn't a good dog. We do have a nice yard, conservatively I'd estimate it's 20x40ft, and frankly choosing between a calm or active dog I'd pick the later because It seems so much simpler having a dog that's acting crazy and all it needs is to run around at the park for a few hours and go for a walk in the woods for an hour. Way easier than a dog that sits around being lazy and getting fat like a lab, and definitely less stress than a pug or English bull dog that you have to be careful to give them the right amount of energy so they stay healthy but don't overexert themselves.
