Think twice berfore you keep a pet (rivision)

In recently years, many moviemakers use animals as the main characters that impress audience with the affections between them and human beings. Such movies as《A tale of Mari and three puppies》、《Quill》、《Cats and Dogs》、《Eight Below》、《101 Dalmatians》,etc.. Dogs like Shiba inu、Labrador、Beagle、Husky、Dalmatians were very popular during the movies were playing in the theater. People bought them and afterwards found out that it was not easy to keep pets, especially it costs a lot of money to buy food, to pay for illness, to deal with everything that pets need. So, tragedies happen：innocent animals are abandoned.

To make a thorough inquiry, why adopting animals that appear in movies becomes a trend for people? I came up with some points：
(1) Curiosity：People are often attracted by the affections between animals and their hosts, so many of them imagine that whether it will happen to them.
(2) Fresh feelings：many of the animals first appeared in the movies when they were young. And as everybody knows, young animals are always so cute that it is hard for us not to look at them or even own them.
(3) Advertisement：Businessmen only care about the profits movies bring. So they do their best to publicize the movies without paying attention to the effects that spread out through the public.

Besides,there are some ethical issues such as "Do animals have feelings?" that we should pay attention to.I will talk about the aspect of animal welfare or animal rights by using information from wikipedia and journal articles.
