So, we adopted this chihuahua. He's a cute little dog, but we might have to name him Houdini because he learned how to climb the chain link fence today. I have been looking around this morning for ideas of how to stop this, but haven't thought any are the perfect method. So far, I've seen people recommending: invisible fence, shock collar or fence modification. The fence is only 4 feet tall, so it's pretty easy for him to climb now that he knows how to stick his feet through the holes in the link. Invisible fence might be too expensive and a little cruel. Shock collar is an okay idea, but we have to use it properly for it to work, it's also painful like the invisible fence. Fence modification seems like a great option, but I have about 450 feet of fencing that he has access to, so it would have to be something cheap. I know the shock collars and invisible fence aren't that cruel. I would rather shock him a few times than have him get out and ran over by a car. If it comes to that, I have no problems shocking him, but Mrs. Magic doesn't like the idea. She wants fence modification. I'm pretty much open to any suggestions here, this has to stop!
