Hi, I am new here and am searching for help from everyone. My puppy's name is Thor, we got him on Jan. 11 at 8 weeks old. He was constipated as a Very young puppy and the breeder (whom is a family member and we know VERY WELL) took care of him, took him to 2 different vets and he seemed fine after treatment.
At about 10 weeks he started SCREAMING, and "crying" with every bowel movement attempt, and also has an almost constant discharge (just light brown watery with a "poopy" smell). Now he is 17 weeks old and on Prednisone and butorphanol .2 cc, 3 times daily. The crying is a bit better but in the mornings, after going all night with no medicine, he will scream and cry with his bowel movement, and the discharge is still there.
This discharge is also an issue because it makes him smell awful and I have to give him "butt baths" (as the kids call them) every day to avoid him being really smelly. Not an issue for me of course I will do what it takes to keep him clean. I just put him in the bathroom sink and wash his bottom with warm water...but I would think this is making him raw back there also. We tried baby wipes to just wipe him a few times a day but that makes him red and irritated back there.
He is doing great on house breaking. He is being indoor puppy pad trained and goes to the paper for every bowel movement and 80% of the time for urinating. So for a Yorkie that young I think he is doing awesome. He is very active, alert, playful and normal except after a bowel movement. After a bowel movement he acts scared, hurt, and sad

It is really hard to handle it and it is getting to the point that when he starts to head for the paper, every one runs to their bedrooms and shuts the doors so they don't hear him. I have tried everything; petting him while he uses the bathroom, talking to him in a soothing voice, giving him treats after he is finished, and just sitting there for support but none of this helps. We all love him and want him better but have no idea whats wrong with him.
He has been to the vet an average of once a week since we got him, we are trying to find out whats wrong with him. The vet says it could be neurological but I think that he would act "off" all the time if that were the case. The vet even hinted at PTSD (post-traumatic stress disorder) due to the constipation as a very young puppy. He said that he may be afraid to use the bathroom so he is trying to hold it in as his body is trying to force it out, causing issues. He has checked his internal organs, and says everything feels normal, no swelling, enlarged organs, constipation, or hernias. We have done multiple stool samples as well with no abnormalities. He is up to date on all of his shots and also on heartworm medicine. He was started on the prednisone and butorphanol 3 weeks ago hoping this would ease whatever is causing it, but it still isn't gone all the way and honestly I am afraid of the long term effects of a steroid and narcotic on a puppy so small and young but it does seem to help him during the day so we keep giving it to him.
Sorry this is so long, but I wanted you all to have the details for a better chance of finding out what is wrong. If any of you have ever heard of this or seen it before PLEASE HELP US
Here is the video I put on youtube so that you all can TRY to help us figure this out. We really love our puppy and want him better.
I have never used a video in a forum so all I know to do is post the address... please be prepared, it is painful to watch and we have to listen to this 4-6 times a day but we need answers. We love our puppy and just want him well.
