From your description I would say the F1 English show cocker x miniature poodle is the cross you are looking for.
...although an adult Wheaten will be a pale biege 'wheat' colour. Maybe they think he's a wheaten puppy as they have red/brown/black colours? I keep getting asked if mine are Bedlington's and an unclipped Bedlington does look a little like a cockapoo I guess.I'd agree with the other comments. Ryley's often been mistaken for a wheaten, he's from from show cocker bitch and miniature poodle stud.
murphy is now 5 mths, he may, i know go curly, but at the moment has thick wavy, human like hairThanks so much. So best to look for a mix of show and a mini daddy. Lee, how old is murphy now? Will go over the pictures again.
Thanks again
