If you ask me, small dogs are in general cuter than big dogs however when it comes to taking care of the smaller stature canines, you have to be extra careful so they don't get hurt. There are a variety of ways you can take extra care - here are a few of the primary ways.
First, you have to be careful just in your day to day activities. For example, you can't afford to accidentally fall or stumble on them. This might sound far fetched, but imagine two kids horse playing around and one pushes the other and the diminutive dog doesn't notice, this can be trouble. Thus, it's better to have a more mature household just for care in the practical sense.
Second, these types of dogs need to have their diets carefully monitored. Just like big pooches, they have eyes that are bigger than their stomachs and will eat until they literally can't anymore if they like the food enough. With this in mind, you have to consciously make an effort to limit their portions relative to their body size. Along these lines, you must be extra cautious not to leave any dangerous things they might eat such as chocolate or other candy.
Third, you should let tiny dogs stay inside. Simply put, a full time outside life is too dangerous for them. They can't withstand the same elements and dangers that normal sized dogs can. Owls, snakes, ants, and weather among other things can pose big time problems.
