Excitement. When they get excited over something (such as food), and go running (or crawling) towards you at top speed they often lose their balance and fall due to their extreme level of elation.
Debris. You need to make sure to pick up anything that is within their reach unless you’re ok with it going into their mouths (and possibly being swallowed)
Teeth brushing. If you’ve ever brushed a puppy’s teeth then you know what I’m talking about.
Discipline. When disciplining a puppy or a toddler there is a frequent amount of repetition until they finally concede to the notion that you are the one in charge.
Forgive me eyes. When they’re in trouble they look up at you with their cutest, big beautiful “I’m sorry” eyes in the hopes that you’ll forget all wrong doing and just melt at the cuteness overload.
