Dog Health Questions: Dog not walking on leash?

im a dog trainer at petsmart, went through school and everything got my diploma for dog training, i have worked for the company for 3 and a half years, there is a bulldog in my class that is not treat modivated, when the harness and the leash go on, the dog will not move or even walk on the leash, i tried treats, praise, and even pulling on the leash to force the dog to walk, it will just go flat and looks like its mopping the floor, i have even gone through the back ground of the dog and it has 2 other bull dogs that are 2 years older than she is. theres another trainer that has an advanced class going ont he same time i do, and even tried opening up the 2 other doors and having the dog walk around the bulldog and out one door to another into the training ring, to see if the dog would follow behind to see how one dog walks on the leash, still nothing happened, if anyone knows how i can get this dog to start walking i would really appriciate it. thank you.

If getting out in front and coaxing doesn't get a puppy moving, try dropping behind it and running by in baby steps calling ''Go, go, go!'' In a happy, excited voice.

Dog Training: It's Not Just For Adults Anymore

• You've met your match. Check and mate dog trainer guy. It doesn't sound like the dog needs obediance training. It just wants to sit there and not eat...it just needs a dusting once and a while. Maybe tell the owner to place him next to a door to prop it open.


• There is something wrong with that dog. Find what is wrong and solve it.Put some jingle bells and when he does not obey, move them. When he does something good, as little as may be, reward him.Who knows!Perhaps positive reinforcement?


• Interesting... sorta like Bandage Paralysis only this is Leash Paralysis
  What happens when his owner puts a leash on him? It is different with a harness than it is a collar?
  
  Any indication of when/how this started and/or how long it has been a problem?
  
  Outside of the situation with the leash.... if you work with him off-leash... how is his behavior? what motivates him? (lots of strong-willed dogs will not work for treats)
  
  Is the owner working to establish "Alpha" over the dog... doing things like asking the dog to wait while the owner walks through a door and then letting the dog walk through
  
  How about food... is the owner getting the dog to work for his regular meals?
