Almost every day, the dog comes by to visit Smith and her own dog Willie.

According to the young woman, Toby's owners are elderly, and he loves coming over to play.

Sweet Toby was on vacation for a week, however, and he clearly missed his neighbors while he was away.

In the viral , Toby can be seen lurking around from afar.

"I was watching TV in my room and I heard his little bark outside my window," the dog owner wrote in the onscreen text.

"Of course I had to go say hello," she continued, adding that "he is the HAPPIEST dog I ever met."

After Toby finished his rounds, he waited in the grass for someone to come and greet him. Soon enough, Smith is outside, walking towards her animal buddy.

Toby can no longer contain himself when she pets him and does a few joyful laps in front of her to express his excitement.

"He's the best neighbor around," she concluded.

But where is her four-legged friend Willie in the recording? The cheeky caption next to the video gives a hint.

"I missed Toby but I don't think Willie did," she writes, adding a laughing emoji.

A look at the rest of Colleen Smith's channel quickly clarifies the situation.

Her own dog Willie is something of an introvert, and this Golden Retriever pal is anything but!

Willie would rather have his peace and quiet, so Toby's vacation was probably a little vacation for him as well.

The dogs can be seen hanging out in other , and – though Toby definitely wants to be friends with Willie – the black dog is a tad more skittish.

Now that the gregarious pup is back, Willie has to share his owner with the energetic neighbor dog once again. C'mon, Willie – you know you love him!
