Hi Kendal and Lady amanda thank you for the help. i have one more question why are so many people against buying a cockapoo dogs? this was told to me on a dogs forums.
A cockapoo is a mutt, so if you are purchasing a puppy, you are probably purchasing from a backyard breeder (mixes aren't recognized by any breed club, and "generation" doesn't matter). Typically with mutts where you know the lineage, you look at whatever breeds are in the mix and expect:
a) a fairly even mix (not sure, but I don't think this happens too often)
b) one predominant breed showing in personality and/or looks
c) the worst traits of both (Puggles are a good example of this in personality, from what I've read)
Personally, I would not purchase a mutt from anyone breeding them on purpose, since it adds to the dog overpopulation problem and euthanization. If you are interested in this type of mix, look at shelters and rescues (or breed-specific rescues, sometimes they take in mixes), as they will have lots of mixes.
If you are interested in a full bred puppy (poodle or cocker spaniel), I know there are ways to make sure you aren't buying from a BYB or puppy mill, and you will end up paying for the quality, but ensuring your dog has a home if something happens and you cannot care for him any more. Some of our other members may know some links to help you with that, but I don't know them off the top of my head.
Why exactly do you want to go for a cocker/poodle mix (you know a 'cockapoo' isn't a breed, right?) instead of just a cocker spaniel or poodle?
I can think of a BIG con of a so called 'cockapoo', namely that the name is used by back yard breeders and puppy mills, it's a 'designer dog'. I'm not really a fan of those... I hope you've found a responsible breeder. Of course it's your choice entirely.
If you suffer from any kind of allergy and you want a dog, you should first spend some time around a dog of a particular breed you think would fit and see if you get some kind of allergic reaction. If you don't get any reaction, there's no problem getting a dog of that breed for yourself.
