Wolf sitting bug

As the title of the thread says, I have a problem with Wolf sitting bug, when I tame wolf (dogs), bring it back to my house, and after a little while they can't get up, I try hitting them with the sword, first time they just ignore it, but when i brought other wolfs, they were hostile to me, and they attack me, so I had to kill them to. I'm playing on the latest version, 1.7.10.
When i save game and quit game, next time I get in my save, they can't stay up, i tried pouring bucket of water near them and so, but it didn't work.
Please help?

Thank you.
