Do dogs have sense of time?

The answer is yes. Have you noticed how your dog gets excited when you return to your home? It seems that they are equally excited when you return after 5 minutes and after 5 hours. But their happiness and excitement isn't happening because they lack a sense of time, it's because they were feeling lonely and they like the presence of people especially their owners. They enjoy people`s company. And have you noticed the same thing when you wake up? They get all excited again although you are right next to them. Other fact that they are aware of time is that dogs usually signalize their owners when it's time for them to go out, eat and etc. There are many dog owners who will confirm this by saying "my dog knows the exact hour when it's time for eating". Dogs do have sense of time, so next time when you get back home and your dog jumps around you should know it's because of its love not because of the passed time!
