I often walk my dogs with Sue from the Mayhew - she's pretty convinced Ozzy is mostly a Collie although she says he does have spanielish ears. Her first dog was a show Cocker ( a Lochranza bitch
), so she does have quite a bit of knowledge of the breed, although I'm not sure if this extends to working lines.
Ozzy's first owner was in no position to bring up a pup - she's disabled, couldn't cope and so confined him to the bathroom.
Unfortunately this means he arrived at the Mayhew without any socialisation at all and not even toilet trained - he's not good with other dogs, can't be homed with children and requires a very experienced owner to provide the training he requires. All very sad really.
