Not anymore. There is a thing called the PETs Scheme which has certain countries on its list which it is available to. It basically means the quarantine is only 1 or 2 days to check the paper work and microchip. You can read more about this here:
It means that you could take your dog on holiday with you and back again without any problems so long as its one of the listed countries.
I understand what you are saying about seeing the littermates and parents. One of my main issues with trying to find a pup is that I have a severe anxiety disorder, mainly social phobia which stops me going out in public alone. My husband works so my only real contact with people is online. I wont use phones either which again limits my chances. I get really bad panic attacks meeting people I dont know and so I cant work, medically signed off for over 2 years now. Im hoping that my new pup might help me a bit because I will want to take her for little walks and having her with me might help my recovery somewhat.
