Mastiff question...?

Is it true that you have to train a Mastiff differently than other dogs? And also my Mastiff is about 2 years old and is not house trained (When he was a puppy my dad got really sick with cancer so he didnt get properly trained) Is there anyway to "Retrain" him...every time i ever let him in its like he gets this uncontrollable urge to crap everywhere...and he is a mastiff so its aaalllooott of crap... And i want to be able to bring him inside but so far he is making it impossible.

Oh trust me i know he Sure aint the sharpest tool in the shed..If he was human he would be Blonde!

Please don't hate me for saying this, but everyone I know who has had one says they are stupid dogs. I've never had one, so I don't know if that is true, but other people have told me they are not easily trained for anything.

All dogs are creatures of habit. They poop the same place all the time. Walk him first until he goes and goes and goes. Then bring him in. See if that helps.

try bringing him in for very short periods & gradually working up. take him out every 15 minutes or so for awhile. sounds like he is very nervous when inside.

Make sure to praise him when he goes outside.

If you feed a good holistic food he will poop less

I have a mastiff and he is not stupid, but is very lazy and stubborn. As far a trainging goes, if you enroll him in a obedience class and your are consistent on working with him every day he can be trained.
