@Sponge19 that's a bit of a spiteful comment, op is clearly new to this and is trying to get information, they have clearly taken on board what posters have said.
Op we got out first dog in sept 2020 and were shocked at what a minefield it was. We initially looked on pets4homes (not knowing any better) and almost bought a puppy but when we tried to do all the checks, the breeder backed out on the day we were supposed to collect her, turns out they were puppy farmers (who without all our digging looked totally legitimate)
We ended up having an 8 week old puppy born at rspca. Total mongrel, not what we ever though we would have... but fate was looking down because I'm now absolutely sure he is the most amazing dog in the world ever!! 
We thought we were totally prepared, did all the research about training a new puppy, the other big shock was exactly how much time attention and constant training an 8 week old puppy needs. What I'm saying is, although your DH is wfh, he won't get much work done for the first month or 2! And those needle teeth!! Basically it's like having an over tired toddler hyped up on sugar who has teeth like needles and like to put everything (including you!) in its mouth! 
once past that stage, after about 6 months it gets much better... but it can be a shock.. especially with children who may become nervous of the dog , as the puppy has to learn not to bite.. for the first few weeks while they learn about using the pressure of their mouth.
Don't let this out you off though, they are absolutely worth the effort, mine is now almost 2years old and is wonderful! Best thing we ever did!
