Firstly, I am really sorry to hear about your beloved cat.
I know that you have asked for advice on what to expect if you go ahead with a puppy and I apologise if I am speaking out of turn but it seems like a lot has happened to you in a very short space of time. You lost your lovely cat of 19 years, you have just taken on two kittens and now you are considering taking on a puppy. You sound like a lovely lady but it seems like maybe you are taking on too much in a short space of time.
Having a puppy is a bit like caring for a baby!

They require so much attention and lots of training. You say you met a Cockapoo on the street and fell in love, which I can understand as they are gorgeous but have you properly considered whether they are the right breed for you? Am I right in thinking that all of this has happened in the last week? I am slightly confused by the timescale so apologies if I have got the wrong end of the stick!
If you go ahead with the puppy you can probably expect disturbed nights, early mornings, toilet training which will involve taking the dog out at regular intervals and constant supervision whilst you are looking for signs that they need to go. It is important to attend a puppy training class and socialise the puppy. If you are lucky and end up with a dream puppy then this might all happen in a few weeks but it is not always that easy! Most dog owners experience blips during the first 18 months when the dog goes through the 'terrible twos' and then a 'teenage' phase where they can start wetting again in the house or their recall can disappear!

Most people who I have spoken to suggest that the first two years is hard work but if you are will to put the effort in you will have a great dog at the end of it.
Who will care for the puppy whilst you are at work? Do you have time for two walks a day?
I don't mean to sound negative but I really do suggest doing a bit more research before going ahead with this purchase. I am sure that you would make a lovely owner and that the dog would be good company for your husband but I think it might be worth just sitting back and thinking about how you will fit the puppy into your lifestyle.
You could maybe consider a rescue dog. If you talk to the rescue centres they will match a dog to your lifestyle and help find you a good companion for your husband without you having to go through the puppy stage. It is only a thought and I do appreciate that you have already paid a deposit. Would the breeder hold your deposit for a future litter?
Maybe other people will come on with different advice!

Whatever you decide to do I wish you the best of luck.
