Ours is lovely. She’s so friendly with other dogs and humans, we did a lot of training with her to get her respecting people’s boundaries. My dog has had toys and stones thrown at her by children (we don’t have children, so these are children who are strangers to her) and she didn’t react (I certainly did though).
Ours has always been a bit more independent than any other cockapoos we know, who will stay close to their owners side at all times. Ours is also more intelligent than the other cockapoos we’ve known. That’s not a boast because with that intelligence came a whole bunch of attitude. We had to work harder with training than anyone we know with a cockapoo but now that she’s 3.5 years old, she is such a good dog. This is a boast but she’s one of the best dogs we encounter (and due to training we encounter some very good dogs). This isn’t me seeing the best in her just because she’s mine - 18 months ago we were the worst. We had a hard teenage phase.
As a puppy, she was very energetic. Needed a lot of brain games. Walks only did so much to tire her out, so we had to do different things with her, get her thinking in different ways. We did (before lockdown) a lot of things with her to keep her brain busy. Now she’s a bit calmer, she’s happy to do any of the games, flyball, agility or a big walk but she’s also happy to have lazy sundays.
As I said, ours has always been more independent than other cockapoos. She was fine in another room to us and would frequently get bored of us and take her self off to lie in another room! We worked full time out of the house before lockdown and she was fine, although we do have a dog walker who pack walks with her.
There is a lot of variability in cockapoos. So the main thing is to look at the temperament of the parents. Even then, dogs will have their own personalities.
