Giant Great Dane Is Best Friends With 5-Pound Dog

She weighs 100 pounds more.

Greta and Rio joined their family within three days of each other, and ever since then, they've been inseparable.

"Since we got them at the same time and the same age they are essentially sisters," Haley Bond, the pair's mom, told The Dodo. "They LOVE each other. Absolutely best friends. When one leaves the house the other is visibly saddened."

Greta and Rio love spending all of their time together, and don't really seem to notice that one of them is MUCH bigger than the other. Little Rio, who's a Chihuahua/Yorkie mix, weighs only 5 pounds. Greta, a Great Dane, weighs 105 pounds. Despite the obvious 100-pound difference between the two sisters, they do absolutely everything together, and hate being apart.

"They nap together a lot," Bond said. "They wrestle. Greta likes to play keep-away with toys which drives Rio insane. Sometimes Rio will latch onto a toy Greta is playing with and Greta will run dragging Rio behind because neither wants to let go."

One might think that since Rio is so much smaller than Greta, Greta would feel the need to protect Rio, but instead, Greta knows that Rio can always take care of herself.

"It's funny because when we walk the two of them together, Rio starts to pick fights because she knows she has back up," Bond said. "And if Rio does pick a fight, Greta will definitely step in if Rio is in over her head. That can be a handful."

Because of how well she and Rio get along, Greta has absolutely no idea how big she is, and that her size might intimidate most other small dogs.

"She doesn't quite know her size, so she'll try to play with small dogs on the street and it scares the crap out of them," Bond said.

Not Rio though. Rio could never be scared of Greta, because the two sisters are the absolute best of friends, no matter their size, and will always have each other's backs.
