Hi and welcome! There are a lot of good threads on here about looking for a breeder, you could try in the puppy section. Reccomendations are always good but will also need to have a think about the type of Cockapoo that you would like as their are different crosses.
English or American Cocker spaniel?
If English then working or Show Cocker Spaniel.
There are a number of health tests that should be considered before producing a litter so for the long term health of your Cockapoo it is important to find a breeder that considers the health and temperament of their dogs. Below is from a puppy buying post;
• Have a look at a wide range of breeders, call them up and ask lots of questions and go and visit where possible.
Questions to ask
• What health tests have their dogs had? Ask to see the certificates.
• If they are KC registered parents ask to see proof.
• How often do they breed their bitches?
• How old were their bitches when they were first bred?

• Make sure you see mum and dad where possible but always ensure you see the mum.
• Puppies should not leave their mum before 8 weeks old.
• What will you get with your puppy? Most breeders offer micro-chipping, food, 1 month insurance, first vaccinations and a blanket or toy smelling of the litter.
• What after care is there? Will they still support you if needed? A good breeder will insist that you return the puppy to them if things don’t work and will probably have a contract.
• What are the temperaments of the parents?
• Are the puppies used to be handled and the normal hustle and bustle of a house?
As a Cockapoo is a cross between two pedigrees I would recommend that you look at the Kennel Club descriptions of each breed and also the Breed Clubs themselves. They are the experts on the individual breeds of dog and give great advice on what to look for. This will help you greatly when looking at the parent dogs.
