A shelter dog has melted hearts online after a volunteer revealed what happened when she took him home to meet her cat, in a video that immediately went viral.

The viral clip, shared on TikTok in August by @all_dee_aminals, shows the pitbull standing by the window, where the cat is relaxing on her hanging bed, kissing and petting her as she returns the affection.

"POV: you volunteer at a shelter and take a dog to your house to see how he does in a home," reads a caption shared with the heartwarming clip.

After witnessing the pup's sweet reaction to the poster's cat, some users asked if she was going to give him a forever home, and she isn't, but for a good reason.

"He's actually going to be trained to go into a service. He's meant for greater things than my home," she said.

Service dogs are specially trained pups that help disabled people live more independently by performing some specific tasks that are essential for their owners' autonomy.

"The task the dog performs is directly related to the person's disability," the American Kennel Club said on its website. "For example, guide dogs help blind and visually impaired individuals navigate their environments. Hearing dogs help alert deaf and hard-of-hearing individuals to important sounds."

There are currently about 500,000 service dogs in the U.S., Dogster reported, although people in need of a service dog may have to wait up to five years before they get one.

Each year 6.3 million pets enter U.S. shelters, an average of 17,260 a day, according to the American Society for the Prevention of Cruelty to Animals.

The number of dogs and cats taken in by pet shelters hit 46,807 during January 2023, an increase of 1,744 compared with January 2022, the 24Pet 'Shelter Watch Report' found.

Around 920,000 surrendered animals are euthanized every year. Shelters are striving to minimize euthanasia rates by promoting adoption campaigns, spaying and neutering programs, and behavior rehabilitation.

The video quickly went viral on social media, getting viewers from across TikTok. It has so far received over 210,200 views and 32,500 likes on the platform.

One user, Vanessa, commented: "So gentle, this is why it makes me so mad that ppl stereotype all pit bulls as aggressive cause look at this sweet baby."

Tinavenditti659 said: "I did the same thing. He was just coming for a home visit to get a break from the shelter...His break lasted 13 years. lost him almost 4 years ago. I miss him every day."

Lucyannhardin added: "He will make a great service dog. Look how gentle he is."
