I noticed that my 10 week old Yorkie was trying to poop like 5 times in a roll, he was trying real hard and I noticed that there was nothing to pick up. He did the same thing serval times. I looked at his anal and there is hard poop that is blocking him to poop. What do I do? :confused:

Try rubbing his bottom with a warm washcloth. If it doesn't look any better take him to the vet. He could get seriously injured from being blocked up like that.

Have you been feeding him the same thing?
Changed his diet at all?
A sudden change in diet can often result in either constipation or diarreah.

Has he had access to anything that he could have swallow?
Kids toys, bottle caps etc?
Things they have swallowed can often cause bowel obstructions.

Like Megan said... get a warm, wet washcloth and hold it against his anus for a few minutes to try and soften to poop.
Then try to wipe it away gently.

If you can get it off and he is still having trouble then take him to the vet immediately.
