Hiya....I have a cocker, springer combo and I think its great
Whilst they are totally different dogs in many ways (((gets ready for the guns))) one has been alot more easier to train than the other
they have a similar love of active life and compliment each other really well.
As the OH used to shoot we know alot of peeps with springers and other breed, multi dog households and I don't think they are any more troublesome than any other breed but as with all dogs you will always get exceptions to the rule
For us its been the perfect combo and one that I wouldn't hesitate to repeat in the future
