A dog standing on all fours, sometimes with a tongue sticking out. The breed of the dog emoji is largely platform dependant - as is the age, with some vendors displaying a puppy.
The dog emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the animals and nature
category. Because the dog emoji has been around for quite some time, it should display correctly in the majority of operating systems.
