In the dog world, looking into another canine’s eyes can be perceived as a threat. So when you see a dog turning their head away from another dog, it likely means they are trying to avoid eye contact to show deference to the other dog and avoid confrontation. When a dog tucks their tail, avoids eye contact and urinates at your feet when you walk through the door, their showing signs of submissive urination. They may even roll onto their back and urinate. It’s their way of showing you that they are not a threat and that they surrender to your authority. Puppies often outgrow this behaviour, but if your adult dog is still urinating at your feet (or your puppy does it frequently), take them to the vet to rule out any medical conditions. Once you have a good health report from your vet try taking them outside immediately upon coming home while giving them minimal attention until they have been to toilet.
When a dog wakes up from a sleep, or simply gets up after lying down for a while and stretches before coming to greet you and say hello, the common misconception is that they are simply stretching their muscles after a long period of rest. Although there are accasions when this might be the case, it is now believed that this behaviour actually forms part of a dogs greeting behaviour, and has even been given a name, the ‘Greeting Stretch‘.
