Hi.
I have a mini poodle. He was our first ever dog. He's two now and my kids are now 8 and 11.
To be honest sounds like you've put a great amount of thought and research into it.
Mine is certainly fine when left 2-3 hours a couple of times a week.
We live with/next to my parents and so he sees them a lot. We share a large garden with them. On the odd occasion we have gone out for longer than a couple of hours my parents have looked after him. However he's not happy about this arrangement (as lovely as my parents are) and he will stay by the front window mostly waiting for us to come home or just sleep. He's pretty mardy about it.
He's never been a chewer or destroyed anything. He also slept right through the night from night 1! More luck than anything we did though.
He's been quick to train (apart from lead walking which is hit and miss. But then our consistency has also been hit and miss).
He has one walk a day which can be from 30 mins to a couple of hours. We all spend a lot of time in the garden or at the allotment too and he will come with us and mooch about/play ball/ get in the way too.
I will say he doesn't sleep a lot in the day. Poodle's are bright and sociable with their family and so if we are doing anything other than sat on the settee then he is with us joining in. So there isn't much 'off' time. If he's bored and we aren't paying him attention when he wants it he will bring a ball or toy and chuck it at me.
As soon as we settle down though then he's snuggling up with one of us. We had said he wouldn't be allowed on the settee but he's so clean and tidy most of the time and loves his cuddles. We gave in quickly.
I'm allergic to most dogs. But not at all allergic to him. Plus there are no dog hairs anywhere. Ever! It's great. He can sit on my black trousers and leaves no sign!
Grooming is pretty important with a poodle but it also depends on the cut your dog has. Mine is kept short all over and so only really needs a quick brush through a couple of times a week. I do have him at the groomer every 5 weeks or so which is £30 a time.
Mine loves chasing anything - cats, pigeons, balls. But I think it would be different if he had met a cat as a puppy and we had socialised him properly.
Poodles can be a bit vocal. But that's a training issue really. Ours now will bark at the door (but I like that as I don't always hear the doorbell) and will sometimes bark in the garden if he hears another dog barking But he knows what I mean when I tell him quiet and he does usually stop.
Poodles are really great dogs and I wouldn't have any other breed now I've had him. Though of course parentage is as important as breed. You need to know the temperament of the parents too. I do think training and parentage are more deciding factors than breed.
