Bailey's gorgeous, you'll have a lot of fun watching him grow into either a springer type, cocker type, or mixed spaniel
Unfortunately there is no hard and fast method for distinguishing a cocker from a springer (indeed springers and cockers used to be one breed, and pups from the same litter were divided into 'springer' and 'cocker' types based on weight alone
)
The only relatively certain method is to look at the dogs in your pups pedigree to see if they are all cockers or all springers, or a mixture, but unfortunately as your pup does not have any papers you don't have this means of finding out
Good luck with your boy, he's an absolute beauty
