<p>I agree that six months is still young and that the occasional accident is not that unusual. It’s also good that he’s at the door! One thing that comes to mind is that I’d check with your vet to make sure there’s no physical problem. Sometimes a UTI can cause a problem with training. I think it’s more likely that he just needs a little additional time. </p>
<p>Our two dogs are sisters and their ways of indicating that they have to go out are different, as are most things about them! One will scratch/knock on the door out to their yard, and the other one just sits there and makes a noise that sounds like a bird chirping. :)</p>
