My 11yo rescue dog had a really horrible habit of urinating by the back door when he was anxious if we went out. He's not done it very often for the last few years, but this week has been doing it a lot. He seems keyed up which he often is anyway - he's a very stressy, barky, grumpy terrier, but not off food, drink or walks at all. I've another dog (female), but because the wee is where it is, I'm almost 100% sure he is the culprit! I've put bicarb and vinegar down to get rid of the pong (the heat isn't helping), and booked him into the vets tomorrow morning in case I'm missing something. Just wondered if anyone had any experience of this at all?
