MollyAA12, i missed your,OP in March. Thanks for coming back to update us.
Spaniel Aid may be able to help you find an ex breeding bitch. I agree with Callistemon, a show type will probably be more chilled than a working cocker.
I had a cocker[oo, sadly he died age 6 from a brutal, inoperable tumour. I loved him but honestly, the most challenging dog I ever shared my life with. I’ve always had dogs, including rescues and fosters , none of them anything like as complex as my cockerpoo.
I know there are some lovely cockerpoo but, my training friends all say, these are not easy dogs. My view is it’s not a good cross. Highly intelligent sensitive miniature poodle x with highly sensitive, clever spaniels. Spaniels can be prone to separation anxiety.
You did the right thing and good for the breeder to take the pup back. That’s one of the other problems, inexperienced quick buck people breeeding any old spaniel with any old poodle. No thought to health or temperament. Rant over
