Stinky I couldn't train a dog to sit if it went ahead and read the training manuel all on it's own. Stealth would be my first thought here.

Second.....let me study this pull competition thing before I make any comments. I look at that dog....as beautiful as he is......as one big genetic issue. I'm speaking strictly of the breed here......not that particular dog. My very first thought.....cruciate ligaments but that's just off the top. Those short straight legs are BORN for knee problems.

can you tell me exactly what breed that is?
