Several have commented about the energy level of any size being a potential issue, and that can be true. If you have your heart set on a poodle (and you're in good company here lol), I'm still going to recommend a miniature.
It's frequently said that miniatures have as high or higher energy level than the other varieties. I'm on miniatures number 6 & 7 and I'm always puzzled by that perception.
As puppies, yes, they're very busy but mine have all fit right in as adults to my mellow lifestyle. As adults, they like to get out in the yard and play a bit, and they're pretty insistent on one neighborhood walk a day but the physical exercise they ask for isn't onerous. Draining their batteries thru "brain games" like training, which is like a game to them, helps with that.
I'd also recommend looking for an older puppy or young adult. Breeders sometimes hold back a pup with show potential who eventually doesn't make the cut and will go to a pet family, as their siblings did earlier. Sometimes an owner's life circumstances change, and they will take that pup/dog back to help with rehoming.
Many breeders do temperament testing at 7w for puppies, but environment plays a role also. If you can find a bit older pup/young adult their personality and temperament will likely be more set.
My girls came to us at almost 2y old from a breeder who was changing her breeding program. We had 14 amazing years with them.
If you don't mind telling us what province you're in and how far you could travel to meet a breeder and pup first (can't stress too much how important this is prior to committing), we might be able to make specific breeder suggestions. We'll also always recommend the Poodle Club of Canada for breeder referrals.
