Wiley the dog weeps at owner’s grave, but is it actually crying?

This is why dogs are such amazing animals! A dog cries at the grave after grandma passed away.

We know dogs are incredibly loyal. One lay at the foot of Navy SEAL Jon Tumilson's coffin during his funeral and a German Shepherd attended mass every day for months at the church where his owner's funeral was held.

Now we are seeing a video showing a service dog named Wiley "crying" at the grave of his handler's grandmother.

While dogs can get emotional for a number of reasons including the loss of a loved one, it's hard to imagine a dog crying. The video has received more than 130,000 views and YouTube after it was uploaded by user sarahvarley13 and reaction varies.

"This is why I love dogs more than humans, dogs are loyal and will never back-stab you," writes one commenter on YouTube.

"So sad...I hugged my dog something like 50 times after I watched this video," write another. Many of the more than 200 comments extol the dog's loyalty. But not everyone sees it that way.

"Looks like an allergic reaction," writes one commenter. Others also suggest the dog may have an illness or being doing some sort of reverse sneezing. Some believe the whole thing is a hoax.

No matter what people write, Wiley's handler says it's helping her cope.

"I'm not a vet so I can't say if he is reverse sneezing...I can tell you that he has never done that before and hasn't done it since," reads a YouTube comment by the handler. "I may be anthropomorphizing his actions but it’s how I'm choosing to deal with loss."
