My dog will not poop outside

He is most likely being defiant or doesn't understand that he is expected to poop outside. Is your puppy on a feeding schedule or do you leave food out for him at all times?

I would suggest trying a schedule of feeding him at the same time every day, and then taking him out immediately after he finishes. Take him out 30 minutes later and every 30 minutes until he does his business outside, and then reward him for his behavior.

It shouldn't take long for him to realize that he gets treats and loving every time he poops outside.

no not medical. He is getting back at you for leaving him in that crate all day. and yes they do that.
try to notice when he dose it or around what time and then like 10 miniuts before that time take him outside and wait and when he poops make it a giant party right there and give him his favoite treat after a while of this he will get the hint.

I think there is something that can help you in pet accessories shop.
There is some spray that can spray at any place,
which will cause your dog to poop at the place which you spray.
That spray contain some thin smell that only can know by dog,
and cause dog to think it's the place he/she should poop.

Is he going in the same area each time or hit and miss? If he is going in the same area he might be attracted to the smell that he leaves behind.

This is just an idea off the top of my head here but if he goes in the same area, condition that area to make it the same as outside. Cover it with plastic sheeting and cover that sheeting with dirt and leaves from an area in your backyard. Let him get familiar with that area and when he goes take the whole thing outside and dump it where you want him to go. Leave him in that area and see if that triggers him to go outside. Repeat as needed.

Dogs leave scent markers when they go to the bathroom marking their territories and he is marking him, give him a new marker spot and see if he uses it. Also eliminating the markers inside with those products the stores carries can't hurt either.

You could also try to spook him a bit by letting him think you have left the room and if you see him getting ready to go, blow a whistle or a bell or something like that. By making it an unpleasant experience he might wait to go outside if he has a safe area to go.

Sounds like my puppy .she would go pee outside and would poop all over my house .it got so bad she picked an area and would just go all in that one area.The vet said we had to catch her in the act(scream no) and then take her poop outside and put it in the grass. This went on for a few weeks but she finally started going when she is outside and for walks.She still sometimes will go in that one spot and it makes me nuts,but over all she is doing much better over the year.Puppies need time to adjust and learn.Just keep working with the puppie and it shall work out . Working with them is the key.

maybe it is revenge...getting you back for leaving him home all alone...

my late shihtzus used to make a mess in the house when i leave them alone at home to get back at me. so, every time i go out, i get them a little snack or treat so they dont feel bad of being left alone at home, or at least, start to look forward to the treat they will get when i return home.

i think maybe go out with him...either take him on long walks to make sure he does it, or sit outside with him in the backyard and make she he will do it in front of you.

I dunno much about dogs; except maybe my own, but I learned the hard way.:) I have no such problems with my dog coz she is an outdoor dog. She stays put in the yard, and I take her for two long walks per day, and she poops and pees during the walk.

About your dog, the only idea that goes into my head is to take him/her out just when he/she is about to poop. Maybe then he/she will get the idea then.

Cheers and wish you luck

He needs to have an "ah ha" moment when he realises what you want him to do. You need to feed him, take him outside, wait with him until he goes and praise him like mad. You also need to clean every trace of where he has been from the carpet so he doesn't think it is his toilet and make that his regular place. It also helps if you pick up every trace of his poop from where he has "been" outside. I know it sounds like a contradiction with what I said about carpets but, in the yard, they only seem to go in a clean spot whereas inside, they seem to go where they can smell themselves. It can be a long process. My boy, who has just turned one, took what seemed like ages to learn about potty training but they DO eventually learn as long as you are persistent and consistent with your praise when they do the right thing.

Does he play in the yard any? A lot of dogs won't go poop in their own yard. Another thing you can do is try giving him a treat when he goes poop outside and not when he is inside. That's how I got my dogs potty trained. Best of luck!

I am having the same problem. I have a 12 weeks old great dane and he does poop outside but he waits as long as he can which is over 30 hrs, he poops outside and when we leave him in the crate he poops again. we give him half hour each time he poops incase he has to do more. when he does poop he gets treats outside and praised big time. I am at a lose to and finding myself sooo frustrated with him. I thought dogs were not suppose to poop where they sleep and i can make the crate any smaller or else he wont be able to lay down which is not fair. Anyone got any suggestions cuz i have tried pretty much everything that i have read and can think of.
