hi
we have two vizslas- both girls. my step daughter has aspergers and i can't recommend the breed highly enough. the girls are a little smaller than the boys.
we got our first as a puppy, then 9 months later got a second rescue puppy (look up vizslamentes on facebook- you can get a puppy thats a little older, but that does not have the training/ issues of an older rescue dog). the main reason for getting the second was although we work from home the breed needs lots of love and attention and we could not give her that full on 1-1 i felt she needed all day. they are so affectionate and cuddly; its like having a child. they would suck all of someones affection if you let them, so i caved and got her a friend.
our dogs are both still under 2, were very bouncy and boisterous. however with some regular training we managed very easily to get 90% of their crazy behaviour out by the age of 1, the last 6 months has seen a noticeable difference. They calm down and sleep most of the day as long as they get two good walks a day (or a fair few small ones if you dont have time everyday for an hour a go). my only criticism of the breed (and its more on us than anything) is that as hunting dogs we have to be really careful that they dont run off after squirrels and rabbits- we need to take them to extra training really. the breed is pretty easy to train, mine are affection orientated not food- so its all about praising them.
having never seen little children/ babies before we were very cautious of our puppies around little family members and friends- i was so pleased, they seemed to know that they had to be gentle instantly. there is also something in this breed that senses emotions more than other dogs ive known. they just seem to know when you need a cuddle or to be calm v play time. they are great with my step daughter when she visits- her anxiety seems to lift. they would happily sleep with her if allowed, we give them a basket on the landing so they are close by.
mine respond well to playing, tug and fetch, hide and seek are favourites. we do leave them, not for long, but to go to the supermarket or cinema etc- but ive never left them for more than 4 hours; that would cause chaos. but we have a great dog day care locally, and use dog buddy.com for emergency sitters.
im not sure how old your daughter is, but if there is a way through vizslamentes or one of the hungarian vizsla rescue charities you can get a slightly older dog then i would recommend that, as the initial puppy boisterousness will be over. having said that, with time and puppy training you will get over that.
i would strongly recommend that you find a breeder from show, or 'pet' lines rather than a breeder focused on working dogs. the latter will have a serious hungting instinct (we notice the difference in our two).
hope this helps- but i would have no other breed now, and i have not a single doubt about them around children and especially children with extra needs such as my step daughter. x
