He's an outdoor dog and lives in a kennel. He's a rescue from a farm and it's how he has always lived, just in case anyone thinks we are cruel . Part husky, part tornjak, about 3 yrs old. I've be going to check on him a lot this morning because he's been doing funny barks, as if he wants to get at something. He keeps bouncing around and barking at (seemingly) nothing in front of him. There's really nothing there, nothing on the ground (there's snow on the ground so it is easy to tell) and nothing/no-one around. It is quite odd. I'm quite sensible and I wouldn't start a thread like this unless I really thought it looked like my dog was seeing things.
Seriously, is it possible?
