Please do not be tempted by adverts offering puppies before they are even born or crossbred mongrels. I feel very strongly that the most you should be asked to do is put your name on a waiting list before a litter is even born. If you are asked to send deposits then be careful, anything could happen before the puppies arrive. ONLY leave a deposit when you have actually been to the breeders property and seen the litter AND the parents. You should then be able to choose the right puppy for you before leaving a deposit to reserve that puppy.
My boys will not ever be available for stud to anything other then a pure bred ABBA registered bitch with clear health checks and a good temperament. They are a RARE breed and anyone crossing them does not have the best interests of the breed at heart, imagine the health and temperament issues that could very well appear in these pups. Also make sure that if dogs are advertised as being hip, heart or eye tested that you get the certificates to prove it, anyone can talk a good story !!!
