Of the many iconic duos that Peanuts produced during its fifty-year history, Snoopy and Sally are perhaps the most unexpectedly heartwarming, and consistently sidesplitting. Sally's relationship with Snoopy is different from her older brother, Charlie Brown, but in its own way, is one of the most memorable pairings in Peanuts' canon.

In Sally's younger days, her and Snoopy were each other's playmates and partners in crime; the duo frequently banded together for adventures, and it became evident Snoopy would go to great lengths to ensure Sally's happiness.

As Peanuts progressed, and Sally got older, her attitude toward Snoopy did change, becoming more like Lucy's. This meant frequent arguments between the pair, but sandwiched between disagreements were still many moments of affection, as the pair continued to look out for each other, helping one another or even coming to the other's defense when needed.

10 "Touched The Dog. Good Grief!"

First Published: January 22, 1967

Even at their closest, Snoopy and Sally were known for arguing like brother and sister. This is nowhere more obvious than in this comic strip. Here, Sally tells Charlie Brown he'll have to wash his hands before dinner, because he "touched the dog" – a comment that makes Snoopy outright indignant.

Snoopy takes offense to this immediately, and chases Sally around the room, acting like he is going to touch her clean hands with his contaminated, disease-riddled paws. Their behavior in this Peanuts strip is akin to siblings who like to get under each other's skin and insult one another. Scaring Sally that he is going to touch her, does not do much to calm Snoopy's temper but it does give a laugh to Peanuts readers.

9 "Speak Softly And Carry A Beagle"

First Published: August 8, 1974

After a rude neighborhood kid tries to block Sally from entering the playground, Sally refuses to back down, and she decides to stick up for herself. Taking a cue from the famous words of Theodore Roosevelt," speak softly and carry a big stick," Sally puts her own spin on it, which requires Snoopy: "Speak softly and carry a beagle." Deciding to be a loyal guard dog for Sally, Snoopy roars at the playground bully for Sally so she can finally get on the playground.

The duo is a fearsome match with no bully able to stand up to them. The fact that Snoopy is willing to be Sally's own form of defense is really sweet... and really unfortunate for all the kids that get in their way. Although, Sally takes things a little too far when she tries to take control over the playground with fear tactics and Snoopy eventually reveals that he begins to feel like a can of mace.

8 "I Saw Santa Claus! But I Never Realized He Was So Short"

First Published: December 1, 1990

During Peanuts' December 1990 comics, Snoopy was frequently found wearing a Santa Claus costume, either standing and ringing a bell for donations or just at home listening to Sally's Christmas list. Taking his Santa persona a step further, he takes the cookies Sally leaves for Santa, making her thinks she saw the real deal, causing her to be overjoyed and excited that she has seen Santa Claus in person. Snoopy, being the dutiful pet he is for Sally and Sally alone, plays the part and doesn't spoil the truth for young Sally.

Of course, Snoopy does get the benefit of the cookies. However, Snoopy does genuinely care about Sally's belief in Santa Clause, even when she is slightly annoying to him about it, he never breaks the illusion for her. While Sally and Snoopy may not have always gotten along the best in the later years of the strip, this Christmas-themed comic shows that Snoopy still cares about Sally's happiness and sense of childhood wonder.

7 Sally Walls Snoopy Up In A Tower Of Building Blocks

First Published: February 29, 1960

A frequent playmate of Snoopy's shortly after Sally was introduced to Peanuts, it was not at all uncommon to see the duo playing or spending time with each other. When Snoopy sits by Sally's side as she plays with her blocks, he becomes inadvertently enmeshed in the blocks, later becoming part of Sally's block tower. The fact that Snoopy, who can be quite the temperamental dog, doesn't just knock over the tower to get out shows just how much he cares about Sally's happiness, not wanting to destroy what she has built.

Sally was not the only Peanuts character to be seen when she was a baby; Schroeder, Lucy, and Linus were also featured in the comic strip as infants.

Charlie Brown, who is not used to receiving the nicest treatment from Snoopy, looks on at his dog in the tower with puzzlement. confused as to how exactly this happened. Sally, being just a baby, does not mean to trap Snoopy, but it would not be the first time a very young Sally caused trouble for the Peanuts gang, like when she cries at Schroeder to play "Rock A Bye Baby" on his piano.

6 "Suddenly I Feel Like The Pied Piper"

First Published: October 16, 1959

Snoopy has his iconic happy dance that countless Peanuts fans enjoy – and his rival Lucy hates. Receiving another fan of his singular dance, this time in-universe, is Sally. Having a close relationship, Sally and Snoopy would spend a lot of time together, with Sally looking up to the irreverent beagle. Seeing Snoopy do his happy dance, she is not about to let him dance by himself, so being a quick study, she jumps right in and starts doing it alongside him.

As a result, Snoopy starts to feel like the Pied Piper, the fictional character from the folk tale of the Pied Piper of Hamelin where a pied piper uses his magical instrument to lead the children of the village in the story. Taking note of how he is leading Sally in the happy dance, the pair's bond is on full display as well as Snoopy's unexpected knowledge of classic folk tales.

5 "If You Can't Trust Dogs And Little Babies, Whom Can You Trust?"

First Published: October 25, 1959

Snoopy is no stranger to causing trouble and neither is Sally, especially when she was a baby. When the two band together, some chaos is bound to ensue. Unfortunately for Linus, the duo team up to steal Linus's treasured blanket, and even worse for Linus, the pair are actually successful. Using some genius acts of diversion, Sally is able to distract Linus while Snoopy sneakily yanks the blanket from Linus's iron grip.

One would not think that dogs and babies would be untrustworthy, but Linus had to find out that hard truth first hand. While the outing may not be to Linus's benefit, it is adorable that Sally and Snoopy are able to work together so cohesively that they are successful in their mission. Likewise, they use Linus's blanket to lay on the floor together, as seen in the following month's comic strip, adding another layer of sentimentality to it all.

4 "You Weren't That Big A Help"

First Published: May 4, 1978

When Sally is doing a report for school on animals, she enlists Snoopy's help to not just give her information on the animal kingdom but also presents him in class. Things do not go well for the pair due to Sally's classmates rudely insulting Snoopy's appearance, saying he looks like a moose or a chicken. Sally stands up for him, telling her classmates to cut it out before Snoopy eventually takes things into his own hands and lands a blow on one of the jeering classmates.

All the verbal abuse was not in vain, however, with Sally getting an A on her report, leading her to buy Snoopy an ice cream cone as thanks for his help. Snoopy, staying true to his foodie tendencies, goes a bit overboard at the ice cream shop, seemingly getting a scoop of each of the 49 flavors.

3 "I'm Not Her Sweet Babboo And I'll Never Be Her Sweet Babboo"

First Published: February 11, 1996

It is no secret that Sally has a major crush on Linus. She makes it very well known actually, and she makes it known nowhere more than to Linus himself. Calling him her boyfriend and her Sweet Baboo, her intentions are good, but he cannot stand it. When Sally writes Linus a love letter for Valentine's Day and asks Snoopy to deliver it to him, at the first mention of Sweet Baboo on the letter, Linus blows a gasket. Snoopy will not stand for any Sally slander (try saying that 3 times fast), taking action to defend her by pushing Linus's face in the love note.

While Linus usually got extremely annoyed at Sally for calling him her Sweet Babboo or boyfriend in Charles Schulz' Peanuts comics, he reacted differently in It's the Great Pumpkin, Charlie Brown, where he instead was flattered by it.

When Sally asks Snoopy if Linus liked the letter, Snoopy keeps her feelings as priority, and lies to her that he did. Snoopy wanting to make Sally happy and save her from disappointment is incredibly heartwarming and sweet of him.

2 "She And I Have Something In Common"

First Published: August 30, 1959

People tend to bond over things they find they have common ground; dogs and babies are no exception to this, as evidenced by the heartwarming (but funny) Peanuts comic. When Snoopy oversees Sally playing, he thinks on how much he likes her company and he feels they have something in common but he can't quire figure out what. However, he has a lightbulb moment when he sees her crawling and Snoopy finally realizes that they both walk on all fours.

They both like to steal Linus's blanket and they both walk on all fours, the basis of any good friendship. Given that Snoopy is not usually the biggest fan of people, seen in his sometimes disregard for Charlie Brown and the outright antagonizing he does towards Lucy. Yet, Snoopy had a soft spot for Sally, especially when she was a baby, making their bond all the more special.

1 "Good Grief"

First Published: September 13, 1959

Snoopy cares about few things in life more than his supper. Typically, he will put anything on hold to get his dinner and has even put his pride aside for his evening meal before. In an absolutely sweet gesture from Snoopy, when Charlie Brown calls him for his dinner, Snoopy, who has Sally sleeping against him, does not move an inch despite desperately wanting to run to his dinner.

Not wanting to wake up the sleeping Sally, Snoopy makes the agonizing decision to not run to Charlie Brown for his dinner. Such a kind-hearted act is unheard of from Snoopy as caring as the dog can be at times. The fact that he makes this major sacrifice (for him) of his dinner for Sally shows just how much Snoopy loves her and cares about her happiness and well-being.
