Hi Tina,
Welcome to the forum! I'm relatively new myself, as I'm also about to embark on my first cocker (although have had them in the family for years). My cocker broodiness has been growing since the last family one died four years ago and parents haven't got another.
I am currently not working (partly because I've been looking for a puppy), and plan to be off work and with the pup most of the time until he's at least 6 months old, and will then try to find another job and get the dog looked after by a doggy daycare carer (most of the day).
The first thing my breeder asked when I approached her was if I was able to look after the pup (and dog, when he's older) and not leave it on its own during the day. She would not sell a dog to an owner that was working and wouldn't have the dog looked after most of the day. Cockers are happy, sociable chaps, and I've heard stories of them having dreadful dependency problems when they're left on their own for long periods of time. A friend of a friend works as a GP and has had serious problems with neediness with her cocker for a couple of years (I think it may have working lines, which need more stimulation and exercise than show types). It has abandonment issues, I think, and then gets massively over-excited when she gets home.
I don't mean to be negative, but I would think that most people would agree that you'd need to take far more than a month off (between the two of you) to bring up the dog before just having someone to come and spend a short amount of time. I don't even feel that happy about my own arrangement, but I plan never to leave the dog on its own during the day (apart from obvious occasional trips and short breaks). I'd look into the doggy day care option more - it can be expensive (£25 per day near me in SW London), but the dog is looked after by someone for the majority of the day and exercised and socialised with other dogs a lot.
I'm sure there are people on here who work full time who will be able to help better from their own experience, but you may find it difficult to find a responsible breeder who is happy to sell a puppy to a full-time worker.
Hope this is helpful...
