San Diego, California - Grace the Golden Retriever dog can be seen huddled in a corner of her home, cowering in fear and distress. What is going on in this viral video?

Katie, who lives with Grace and two other dogs in San Diego, California, filmed the moment and posted it on TikTok recently.

In the onscreen text, she writes, "When I already feel guilty for being out of the house so much today and then my dog makes me feel even worse."

The video's caption reads, "Why did no one tell me golden retrievers had such big feelings – i am not ok."

Fortunately, owner Katie is completely transparent, taking the time to explain the situation in numerous comments.

Some viewers are particularly concerned by Grace's tongue hanging out of her mouth and her somewhat haggard appearance, but there is an explanation for this that is as plausible as it is sad.

According to Katie, the dog is lucky to be alive after surviving distemper as a puppy.

Apparently, the case was so severe that the pooch suffered neurological damage and her permanent teeth became damaged/undeveloped.

The Californian regularly posts videos with her dog on her TikTok channel in which it is often clear that Grace has some neurological limitations.

But there are also many happy, loving moments with her owner.

However, Katie has learned her lesson – she can't leave Grace at home alone for such a long time again!

That's why she vows to do better, noting in a comment that she normally spends the whole day at home with all three of her dogs.
