We have a large male labradoodle.
I wanted to rehire a cross breed - like you - and they wouldn't let me as I hadn't owned a dog before and have young kids. Fair enough.... So chose a puppy Labrador/poodle cross as I wanted a large, energetic dog. (Flame me, I bought a puppy)!!
Anyway, I think a lot of these dogs are rehomed just for being very high energy and bouncy with a long puppy hood. I did my research and felt this was the right breed for us.
And by jove, he is. I have a medium energy, large, slightly shedding galumphing beast who I adore. He is ridiculously affectionate, highly intelligent and very sociable around people and other dogs. He can run with me, bike with me but won't trash the house on days he doesn't get such a long walk. Extremely tolerant with the kids. Very gentle. Fun loving, playful.
Based on my experience, I would say they do need a lot of socialising as they can be skittish with strangers (I had visitors give mine treats). They can get lonely if left too long. They eat socks!!! They will try to suffocate you with cuddles. They can be jumpy and that part is hard to train out of them. Lots of people assume you chose a labradoodle as it is a "designer dog" when actually you just wanted a lovely cross breed.
I hope you love your labradoodle like I love mine!!
