Okay so a lot of people are talking about how dogs don't cry, so I'd just like to clear up the reason why they don't; their tear ducts drain into their nose and throat so it's not outwardly visible. If a dog has watery eyes/ eyes with discharge it means that they're ill
technically humans have them too
That dog is probably very ill since it has discharge coming from its eye.
2: She's probably at the vet and getting eye drops
