Be very careful about buying animals unseen. Far better to buy from a breeder known to a trusted friend who can see the animal for you. Puppies, especially those from puppy farms, are very stressed by transport and liable to succumb to various illnesses such as parvovirus if not fully and correctly vaccinated.

I do not know Europuppy but I have heard too many sad stories of sick and dying imported animals. Check with the local vets and welfare people to see whether they can make any recommendations. Also, do not forget that there are various conditions applied for the transport of animals by air and for import to Qatar.
