I don't like the idea of Dogs being out there, but at the same time it's pretty awesome and a tad cute. I mean, think of it like this: You're in a long firefight, it progresses through an apartment complex and it's up to you to snatch the last enemy around but he's in hiding. With out a dog, this can lead to many speculations, one being going out there and probably getting wounded. But with a dog he can sniff the culprit out and you can take him out. Right after all that stress, you head back to base and now you have a companion to sit with and relax with. During battle mind you. So that's pretty cool.
