Dear Andy,
Being a new puppy owner myself I can only tell you just how time consuming it really is. I gave up work purposely to give our new bundle of fluff my full attention and, believe me, it really is a 24 hr job. I had a cocker spaniel before, but he was 2 years old when I got him and I didn't start working full time till he was 8 years old. So he was very well adjusted and fully trained. We had a dog flap for him and every other day my boyfriend would take him to work with him (very quiet small office). I just can't imagine how it would have worked out for our new little one had I not be available 24 hrs a day. I know some people here say that they have managed and it is wonderful that they have, but, really it's such a huge commitment and responsibility - afterall we wouldn't consider leaving a human baby alone even for 4 hours! We have to put the puppy first, not what we want and I would strongly suggest waiting until one of you can be at home for at least the first few months. There is a lot of getting up in the night during the first few weeks so it will be a big strain due to lack of sleep and then there's the problems that Padfoot so rightly pointed out, boredom for a puppy can make them very hard to train/change the behaviour. There are some wonderful doggies (cockers too) that need new Mummys and Daddys and this really might be your best option. Good luck whatever you decide and best wishes. MPG
