Hi - I'm new on here. I have a 14 month old golden retriever puppy named Duke. He's a very well behaved puppy for the most part and very social. Two weeks ago he suddenly refused to enter the house through the garage door and will lay down on the ground, sit down and pull to go the other direction to enter through the front door. He still leaves the house through the garage, but won't enter it that way. The only thing that comes to mind is that a bike fell over on him a few weeks ago when he knocked into it, but he isn't refusing to enter the garage - just the house from the garage. Has anybody else encountered something like this or have suggestions on how to help him work through this?
