I’m not entirely sure if this has worked but I know that my nearly 7 month old pup has been much calmer this last week. He has stopped jumping up and mouthing as much, and has completely stopped urinating over night in his pen. I believe that a combination of the plugin and a stricter routine has worked really well. Even if the plug in hasn’t actually affected his behaviour, I really like the smell, it’s earthy and not too strong.
