I'm curious as to why you should want a crossbreed (nothing against them, they can be lovely dogs) because you never know what characteristics of their parents they are going to inherit. To many people that is their charm, of course!
For example, many people believe that a "Labradoodle" will not moult, because that is a poodle characteristic. However the pup is just as likely to inherit the moulting gene from its labrador parent. It's a 50-50 chance.
If you need a particular characteristic in a dog, it is best to focus on the purebreeds that show that trait.
