thinking of taking this guy home

I don't mean it if I come across rude but we cannot tell you whether or not to take a dog home. We always love to see homeless pets get homes but only if that new home is the "forever home". Only you know your situation and whether it would be appropriate or not for you to own a pet at this point in your life, financially, emotionally, and physically. This little pug is adorable but I have seen you post more than one type of dog and ask similar questions. Are you just looking for what is cute and now what fits into your household/lifestyle? I am sure you know dogs personalities extremely vary from one breed to another. I just advise you to do your reserch on any and all breeds of interest before choosing any dog, and evaluate your home life to see if now is even an appropriate time. Good luck.
