I have purchased three dogs from Heidelberg. The first was a male that had an Undescended t******e. They should have made me aware of the problem but did not. They tell you not to take the dog to a vet when it young as it may become infected with a disease. So by the time he went to the vet and he made me aware of the problem it was too late to return the dog.
My second dog from Heidelberg was a female and lived 3 years till she was hit by a care.
The 3th and last dog was also a female and she had a congenital heart disease so bad that the vet ask why I had not had her in before. It would cost 1,000 to 1,500 to have the problem repaired. She died 6 weeks later.
One out three dogs with no problem, not good odds
