I might bath the dogs twice a year - mud falls right off their short coat and unless they go swimming in a swamp they have very little odour. Usually I flea bath them in the spring and fall. Certainly they are easy to train - if they don't figure out a way out of what you are trying to teach them. In addition they love attention - so they tend to be very happy workers. However, in the obedience ring they tend to be clowns - they show off to the crowd, sometimes in quite embarrassing ways.
Vizslas are lovely dogs to live with, unless they figure out how to open the garbage or the fridge.
One of my dogs has figured out how to open the baby latches I installed on all my cupboards to keep my youngest son out of mischief. The latches may stop toddlers but they are no defense against a clever, determined Vizsla. A common problem with Vizslas is their tendency to thieve - food, toys, socks, underwear, even kleenex hold an uncommon fascination for these dogs. Not all Vizslas are thieves, but it certainly seems to be a common trait. House problems are easily solved by crate training your Vizsla.
