It can work out. OUr dogs have no problem being in the routin of being left 8:30-1:20, 1:55-3:45. As long as you are prepared to give the dog along walk before and after work aswell as lunchtime I can't see a problem.
I have heard cockers arn't the best dogs for being left though, but I do not know from experiance, but do know a very happy cocker that is left, not for hours apon end, he is also well and truely spoilt!!!
The only problem you have is wanting it for a certain time. Don't go out and find a puppy just because it is 8 weeks start of summer holidays.
ALso is it possible first few weeks after you have been back to work to have someone come into the house to let pup out in garden. Only needs be 5 mins 2-3 times while your not there. Just to let a pup do his business! :)
