What's so Funny?
Though opinions on whether or not dogs can laugh vary, the individual who captured this picture appears sure that this pit bull is laughing alongside her veterinarian sister. Though we can't be sure whether they were laughing, this pooch is obviously very much in her comfort zone. This picture attempts to refute everyone who thinks pit bulls are a dangerous canine breed, despite their negative image.
Working at a veterinarian's office definitely seems like there is plenty of time for leisure and games among the cute animal patients. One can easily understand why someone would select a veterinary degree.
