Dub,
The only purebred dogo that I have ever owned, came from a member on this board, that has been in the dogo circles longer than most of the "breeders" on ETHD. Here was my deal with him. I took the pup at 8 weeks. purchase price of dogo was $300.00. I was told not to pay him any money until the dog was 18 months old. If at 18 months the dog was catching, and had not shown any health defects, than pay the $300.00. If the dog had any problems prior to that, either euthanize the dog, or return to breeder. At that point, my only cost was in raising the dog, and time lost. I did not have a 500-1500.00 gamble.
That is someone that cares about the breed and is not in it for the $$$
Maybe you can find a deal like that, or you can shop on the classifieds and take a gamble.
One of USHog's line of Dogo's just hit the classifieds yesterday. $300.00 ..... Maybe she will turn into a dog.
