West Highland White Terrier Puppy Wanted

Good evening! I am a Doctor from Costa Rica. I´m working 2 months at Thoraxklinik in Heidelberg. I have always wanted a West Highland White Terrier, but there are not in my country. I was wondering if you have some puppies for sale. I am not interested in a dog for shows, I am so much in love with the breed. I already have a female Pomerania since 3 years ago. My parents are taking care of her while I´m here. I am a very responsable owner and I do take really good care of my pets. I wanted to know if, in the case you have puppies or a ittle bit older (less tan a year) dogs for sale, if you think it will be posible for me to buy one and taking him/her with me to Costa Rica by December 9th this year. And if possible, if you can help me out with vaccines and pet Passport and everything that could be necessary to take the dog with me. If you don´t have dogs for sale, could you recommend me a well dog breeder in Germany, please? Thank You so much!! Marta Vargas
