This Adorable Pit Bull Refused To Leave The Animal Shelter Without Her Tiny Best Pal

Dogs are known for their fierce loyalty, often forming strong, lasting bonds with their human companions. But that devotion can also extend deeply to other animals. This was exactly the case when a spirited pit bull and a fragile chihuahua arrived together at a local shelter.

Right from the moment they entered, it was obvious these two were inseparable. The pit bull stayed close, guarding the chihuahua and providing comfort in the strange new surroundings. So when a potential adopter showed interest in the pit bull alone, her surprising response caught the staff off guard—she wouldn't leave without her tiny companion.

Abandoned With No One But Each Other

When Merrill, a female pit bull mix, and Taco, a male chihuahua, arrived at Rocket Dog Rescue in October 2014, staff immediately noticed something special. Despite their clear differences in size and breed, the two shared a deep, unbreakable bond. The reason for their abandonment remained a mystery, but their connection was undeniable.

Based in San Francisco, the rescue team prioritized keeping them together, knowing that separating them could cause significant emotional harm. However, finding a home willing to adopt both dogs—such an unlikely pair—proved far more difficult than anyone expected.

Even brief moments apart would send them into tears. Sharing a photo that captured their close bond, the shelter said, "We just couldn’t bear the thought of them being separated or spending months waiting at the shelter to find a home TOGETHER."

Absolutely—Taco's presence during Merrill’s surgery was a moving testament to how powerful companionship can be in healing. Their connection went far beyond friendship; it became a lifeline that carried both dogs through a difficult ordeal.

This touching moment reminded everyone at the shelter that sometimes, the greatest medicine is simply being there for someone you care about. It’s clear why the rescue team insisted they stay together—some bonds truly can’t be broken.

Their Bond Was A Cause For Concern

Merrill and Taco's strong bond was concerning for those who worked at the rescue. In their experience, they knew that people usually aren't in a position to adopt two dogs at the same time.

ADVERTISEMENT

They had posted Merrill and Taco's pictures separately, which generated some interest. Still, they knew that it was going to be tough if someone only wanted one dog and not the other. The true test came when someone took an interest in Merrill.

A Man Came To Adopt Merrill

Merrill was still relatively young and as a beautiful pit bull mix and so many people showed interest in adopting her. The same couldn't be said for Taco, who was already quite old in comparison.

ADVERTISEMENT

Eventually, the shelter found some potential new owners for Merrill. One man, in particular, fell in love with Merrill the moment he laid eyes on her. When he came to meet Merrill, he didn't know what he was getting himself into.

The Dogs Did Something That Left Everyone Speechless

When the man arrived at Rocket Dog Rescue, he immediately signed the paperwork necessary to adopt Merrill. He couldn't wait to take her home. When they arrived to the cage she shared with Taco, however, something very strange happened.

Once the rescue workers took Merrill out of the cage, she and Taco immediately began crying for each other. The dogs' desperate wailing left everyone in the room dumbfounded. The man who wanted Merrill was confused.

They Soon Realized What Was Going On

Merrill's unwavering loyalty to Taco was very apparent that day. Once it was clear that Merrill wasn't going anywhere without Taco, the rescue staff had to explain the dogs' situation to Merrill's potential new owner.

Thankfully, he completely understood. Sympathetic to their situation, he didn't want to be the cause for such a traumatizing separation. The real question now was if this man would be willing to take both Merrill and Taco home.

Though the man felt for Merrill and Taco's situation, he was in no position to take in two dogs at once, so he ended up leaving with a different dog. While the rescue employees were happy to see that one of their dogs have found a forever home, they were still in distress over who would accept Merrill and Taco together.

Finally, they thought of a brilliant way to show that Merrill and Taco were a package deal.

The Photo That Changed Everything

Though they'd already listed Merrill and Taco on their site separately, Rocket Dog Rescue decided to take a different approach to get the dogs adopted together. They created a joint post that explained Merrill and Taco's undeniable bond.

To make things even more adorable, they posted a picture of Taco's tiny head poking out from Merrill's lap! "This dynamic duo has lost their family, their home, and now we can't let them lost each other!" they wrote.

Merrill and Taco had momentary Internet fame, but was it enough to get them adopted together? While many people commented that they would like to adopt the dogs, it was hard to actually find someone who would seriously follow through.

They knew that they had made the right decision in keeping Merrill and Taco together, instead of forcing them apart just to adopt them out. But of all the people who reacted to the post, was there really someone out there who'd be willing to take Merrill and Taco together?

Despite Merrill and Taco's newfound Internet celebrity, they still hadn't found someone to actually adopt them into a forever home. Rocket Dog Rescue kept posting updates on the duo to let people know that they were still up for adoption.

Everyone admired the strong bond that Merrill and Taco shared, especially considering their unconventional pairing. After all, Merrill was a huge, young dog, while Taco was small and old, yet they loved each other as equals.

The family drove to Jodi's house to meet Merrill and Taco, falling even more in love upon laying eyes on them. But Merrill and Taco's journey didn't end there.

Taco was already in his old age by the time he and Merrill had been adopted. It was only when they moved into their new home that Taco's health issues began arising.

ADVERTISEMENT

Taco was afflicted with both a dental disease and asthma, which caused him to have only four teeth and an adorable floppy tongue that always sticks out. It was clear that Taco and Merrill's previous owners didn't care for them as they should've.

A Much Needed Trip To The Vet

After a few months, Taco's new family finally took him to the veterinarian to get a full assessment of his ailments. Taco was actually suffering from heart failure.

His heart was enlarged and there was fluid surrounding his lungs, which made it harder to breathe when combined with his asthma. It was then that the family feared the worst for Taco, who they hoped would stay with them for at least a year.

Taco's fate was not looking great, especially with his failing heart. The veterinarians made Taco's heart problems a top priority, explaining that something needed to be done before it was too late.

Thankfully, Taco's treatment was working and he started feeling better. His heart began to stabilize and he was able to start living the normal life of a dog.

Taco's treatment included anti-seizure medication and steroids because of the fluid around his lungs. While his heart was on its way to healing, he would also be subjected to medication for the rest of his life. Still, Taco was given a miraculous second chance to live his life with Merrill and his new family.

What makes Merrill and Taco such a lovable dog duo is the unbreakable bond that they share despite their unusual size difference. They are two very different dog breeds, but that doesn't seem to bother either one of them.
