All dogs should get as much exercise as possible. A daily walk is sufficient for most breeds. But most small dog breeds, for example Toy dogs such as Pugs, Maltese or Yorkshire Terriers, will get the majority of their required exercise needs just be walking, running and playing around indoors.
Some dogs will patiently put up with little children who pull their ears or accidentally poke them in the eyes, while others will not and map nip or bite back in defense. So if you want a dog who is excellent with children avoid breeds which may have a dominance streak or that have short tempers.
Getting a dog is not just an emotional commitment; it is also a financial one, too. But when it comes to money, not all dogs are created equal. A bit of research goes a long way in discovering which dog breed is best for your budget.
If you do not like loose dog hair and do not want to be vacuuming the house every day, then do not buy a high shedding breed. If you own a high shedding dog you will find hair everywhere! Including on your clothes, on your furniture, in your bed, and even in your food. Additionally dogs that have a high shedding rate need to be brushed more often to brush out the dead hair.
