I love dogs if they are big and not friends. My Aunt's dog is a really big lab, and it's really nice and obedient. My dog is a tiny Yorkshire and it will bark with it's really high squeal at every noise anyone ever makes.
However my cats are awesome. 1 of them is a ninja hunter and can take down birds midflight, and when he's inside, he just chills by whoever happens to be sitting down. My other cat sucks at hunting (tried to catch a bird, it started to fly away, it hit it's face onto the side of the house), but when she's outside, she will come to anyone else who is in the grass on command, and when she's inside, she just chills. I like my male cat better, because my female cat gets pissy when people pet her when she is chillin.
