Probably because we hold humans to a higher standard than animals - we've all been raised to hold it until it's appropriate which is when we're inside and on a toilet. Some animals can be potty trained, it's a bit weird but good for them - most animals are just trained to not wee on the couch and outdoors is left wide open for them as they need. It's pretty socially acceptable for dogs to pee in public and, if you found it offensive, I am afraid I have some bad news for you about the miniature public outhouses they build for squirrels.
