For The Win/ter Break

My big question is why do people say that dogs see different colors from what we see if they cant see from a dog's perspective? A dog can't speak to us and see what it can and can't see. If you think training Is the answer I don't buy it because just like we humans miss understand stuff and don't know sometimes what people tell us dog's can do the same. For winter I am going to take advantage of not having homework and train on my speed and conditioning for speed. Also stay up late watching movies and playing games. My brother will also be coming in town and I would like to spend some time with my mom and brother.
