Dogs have always been one of our favorite animals. They are loyal and brave, so more and more families now keep dogs as pets. However, dogs, like us humans, can also get sick. So when a dog has constant tears, how can we tell whether the dog has a blocked tear duct?
1. Distinguish based on symptoms
When a dog's tear duct is blocked, there will usually be an increase in eye secretions, and it will also be found that the dog's tears frequently overflow from one or both sides of the eyelid margins. In addition, because the skin in the affected area has been wetted by tears for a long time, eczema may occur, with symptoms such as severe tear stains.
2. Go to the pet hospital for examination
After discovering that the dog has a blocked tear duct, the owner can take the dog directly to the pet hospital for such an examination. Usually the doctor will recommend that you use tear volume testing, a fluorescein test to detect the drainage function of the nasolacrimal duct, and nasolacrimal duct flushing to find out the narrow or blocked parts to determine whether your dog has a blocked nasolacrimal duct.
