Look at the animals eyes and tell it how you feel or hom much that animal want to leave the shelter if it communicates then that may be the right one for you. See if the animal has almost the same personality as you if it does then you know that this may become your new best buddy! Remember always adopt from an animal shelter cause pet store aniamls come from puppy mills and puppy mills give aniamls deadly diseses.
Any animal is a big responsibilty. You will have to feed it, if a dog take for walks, if horse ride it alot, pick up the poop, groom it and many more big deals. But if you cant handle doing all that then id advise you to not get an animal or get a small one that doesn't need as much care, like a fish. My opinoun i dont really like fish i do respect them but i like furry things LOL! So if you have to think twice about getting a pet.
When you are choosing your right pet don't judge on the looks and the colors the animal has...you should see what the animal is capable of and how it reacts to you and if it is gental and not shy. who cares if the animal is cute and stuff ya its cute but the animal inside counts that is the main reason or clue of buying an animal.
