Bigger dogs need more exercise than small ones; they also need more food, bigger beds, larger collars, stronger leads, and probably stronger owners. In addition, and for practical reasons they are better suited to houses then apartments unless at street level. During a deliberating or paralyzing illness a large dog may have to be carried into the garden or to the car a procedure difficult enough without the added complication of a flight of stairs or a temporarily out of action.
The size of the family car may be unsuited to a fully grown large dog and the owner may be incapable of carrying it on public transport systems. Very large breeds such as the Irish Wolfhound and the St Bernard, usually have a shorter lifespan than smaller dogs, and while these facts are only generalization they must be taken into account before a purchase.
At the other end of the scale are the Yorkshire Terriers dog breed and other miniature members of the Toy dog breed group. Although many of them are fearless little dogs, their very size can be a danger at times; tiny puppies can be damaged by unsteady feet or by being lifted and carried clumsily.
