[quote=Tiago]Couch potato, since all the breeding programs emphasize on shows...[/quote] aparrently Tiago is an expert on all the ddb breeding programs. (sarcasm) if you want to be sure you have a "endurance bred ddb" check the parent dogs out and see if they fit the bill or check out some older siblings , they may be the same breed but its not pure science.. its 80% luck to breed the qualitys u want the rest is time and money and wits. all in all a ddb is active but not high endurance, from my experience if you are inactive the dog will be glad to be inactive with you , if you like 3 miles jogs or walks i dont belive the ddb is the dog for you. mine tires out after a mile.
