Austin, Texas - Senior dog Grace has been through a lot, but she never lost her love for life or the humans that are most important to her!

The 12-year-old Chihuahua was diagnosed with glaucoma two years ago, which meant that she slowly went blind.

Unfortunately, the pressure on her eyes was so severe that both had to be removed.

Nevertheless, the dog is as sweet and happy-go-lucky as ever.

In a now-viral clip, Grace's favorite human comes by for a visit. While the blind dog is being held by her master, Grandma enters the house.

The visitor first greets the family's other dog, and then Grace – who suddenly realizes what is happening and who is there – enthusiastically joins in.

Her owner gently places her on the floor. Excited, the four-legged friend initially runs in the wrong direction.

But then Grace recognizes exactly where Grandma is and comes to her. Shortly after, the woman picks up the Chihuahua and cuddles her warmly.

Grace's owner Shelby Salmela can't stop raving about the special pup either.

"It melts my heart every time because seeing the pure joy she feels when they're together makes me so happy," Salmela told Newsweek.

"There's nothing better than watching my girl light up like that."

The proud dog owner added that they now regularly film Grandma and Grace greeting each other because of the dog's ever-adorable reaction thanks to her remaining senses.

"Despite her blindness, Grace's sassy personality remains unchanged, continuing to bring us joy and entertainment daily," Salmela added.
