nope,never heard of them you should try them, they're better than those weag coggers!
are we talking strong springers and weak cockers,im wanting a bit of terrier in the mix seen couple cocker russels like their style of working but yes might even be going for springer x,see what comes up just for info...Im not implying cockers are weak, far from it!
I'd quite like to see a pic of a whippet x spaniel though, I must admit!
