I was actually commenting on the original poster's comments regarding 7 week old puppy being left alone while they went to work, you say you collected your puppy at 5 weeks, not the best situation but if the little one has managed to make it to 7 weeks and your with her all the time I'm sure you are doing everything right, if she's eating and drinking and she's seen the vet the chances are Lucy will do very well. As its been pointed out to you her inoculations shouldn't be carried out before 8 weeks and even then the vet will only do it if she/he is satisfied she's healthy weight wise and in body.
I know through working with rescues that sometimes mum will abandone her pups for no apparent reason and its no good forcing her as that can lead to her attacking them and even killing them. I'm glad your furbaby has a good caring home and it would be a good idea when she is all safe about 12 weeks to take her to a puppy socialising class
