It's not about the dog getting to much work , it's about the dog man giving it to much work ,you need to know your animal ,I've known to many lads which can't help themselves and give their dog another slip on the way back to the car after a heavy night , the bunny takes the piss, then the excuses start .get them home wash there feet give them a light rub down kennel coat on feed and kennel up , then in the morning when you take them out to empty themselves look at him to see how he is on his feet check him over and give him a stretch you will soon know if he can do another night
