it may be easier to get a parson russell terrier ,the prt club have there own web site and have a list of breeders or the kennel club have a puppy list ,you would then have to approach the breeder ,to enquire if they are willing to send the puppy belguim and do the nessasary requirements of pet passport, do you intend to collect the puppy ,it may be worth looking on the defra site ,as you may not need a full passport
lol i have a litter due in 6 weeks time and live near a ferry
