@MiniatureRed well done for choosing crate training.
Crates are a valuable training aid and a place of safety for your pup. I've crate trained every dog I've had from a pup, until about 8 months old and then they have run of the utility room BUT should I ever need it, they are then familiar with a crate, recognise it as their safe place and doesn't cause unnecessary stress in what could be an already stressful situation. Think vets, they don't let their animals roam around the clinic so when your dog goes in to be neutered, or needs medical assistance in future, wouldn't you be happier knowing that it's in a crate where it feels SAFE?! Not stressed having never seen one before.
I have a 15 week old puppy, and a 2 year old lurcher. The pup sleeps in the utility room in her crate, she runs to her crate when I hoover (she's scared of the hoover, crate is her safe place), she goes in her crate when we eat and she goes in there overnight. She's never in there for more than an hour during the day. She's happy in there. She was house trained from 12 weeks and is just becoming dry overnight. She rings a bell to go outside, has all basic obedience training in place and we're just starting agility training.
She wakes up at 5am though
luckily I'm a morning person!!!!!
Also a side note @MiniatureRed, poodles are highly intelligent (perfect agility dogs!) so I think you'll be fine, all the poodles I've met have been yappy so brace yourself for that - and remember, dog groomer head on now, please please put a solid grooming regime in place from the start, touch feet, play with nails, invest in a decent brush, learn line brushing, and visit your groomer every 8 weeks
