Magnolia - I think if you had posted on here saying my husband and I work full time thinking about getting a puppy which nanny will also look after - everyone would have said don't do it, you will end up whomping it......
Earnest working part time, doesn't mean not getting a dog, but it does mean planning for someone else to walk it, check in , make sure it's fine.
Yes I find it hard when DH is away, and after getting kids in bed , dog needs to go out for his tinkle, and then again just before I go to bed, but then I don't feel so alone when DH is away, or worried about being in the house, with the kids alone. ( all burgled would have to say to ddog is "aren't you beautiful" and he would mug them for cuddles, but fairly certain at 55kg they wouldn't bother trying to go any further once they saw him)
In winter the only time I found it hard walking him, was when I was sick, but now I have a dog walker he has a relationship with I know I can call her.
So I would just take you time - one you can afford the support you will need (days out that aren't dog friendly.... Holidays) and 2 that you spend a lot of time researching breed or type.... And don't choose based on fashion or looks, but on temperament, exercise needs and also what mental stimulation the dog will need.
We got our dog when he was 6 months old and he is now a year, we are just having our first holiday away....the kids are constantly going on how they miss ddog...I miss him too, but I also know that he is being looked after like royalty, and being kept busy. I am looking forward to out first long walk on Sunday,
Oh and I wouldn't discount rescues, and there are breed rescues if you are interested in labs - I would just do you research into the rescue and make sure they offer good ongoing support, that they properly assess dogs temperament......
