Having had our cockapoo puppy for 13 months now, I can absolutely recommend you DO NOT get one! I wouldn't get a "designer" breed ever again.
She's a bit of a nightmare in many, many ways.
She's incredibly cute and loving (to us. She hates all other dogs and some people) but she's also very needy and barky. She's basically my lap dog. Always jumping up and sleeping on my lap or just getting in my face, follows me everywhere, even into the bathroom and jumps up onto the bath while I'm showering. She cries if I shut her out.
If you need me to expand on why she's a nightmare, just ask!
On the other hand, we have a well behaved, adorable mini schnauzer who's a delight most of the time. Very gentle with everyone, intelligent, very quick to train and happy to sleep most of the day! She's not playful though, except with other dogs, and can be stubborn.
Both are "hypoallergenic" (if there is such a thing. FIL does get a bit sniffly sometimes) but do shed if their fur isn't cut short regularly. Cockapoo goes to the groomers every 3 months and the schnauzer every 4-5 months. It's not cheap. You only have to look at a cockapoo's fur and it's matted.
Problem is, you can research and find the "ideal" dog, but in reality, they all have different personalities so you can't be sure what you'll end up with.
You'll need to spend lots of time and energy on a puppy. They can be a real struggle sometimes and you wonder what the hell you've done and if you've made the biggest mistake of your life. We both felt that way about our cockapoo. It took many months to feel like I loved her. I think we actually hated her for quite a while tbh. The schnauzer, I couldn't wait to get home to see her every day and missed her so much.
