In Potter, Snape's Patronus, a soul-guarding magic spell, takes the form of a deer—more specifically, a doe—as a symbol of his love for Lily, because hers was a doe as well.
The White Stag makes an appearance in Harry Potter as a Patronus Charm used by Harry Potter's future self to guide Harry. Harry's father is also known to use the same Patronus. A Patronus in the form of a white doe is later used by Snape to guide Harry to the sword of Gryffindor.
Snape's patronous is shown to be a doe. Harry's is a stag. In the Deathly Hallows, Snape's patronous is shown to be leading Harry to the sword of Gryffindor in the Dean's forest.

A doe. And in his final battle with Lord Voldemort, Harry explained the significance of this to his adversary, and to us: 'Snape's Patronus was a doe,' said Harry, 'the same as my mother's, because he loved her for nearly all of his life, from the time when they were children'.

1 Albatross
As the rarest Patronus in the Wizarding World possible, the Albatross represents an enormous bird that flies freely across any sea. This rare Patronus represents those who are simultaneously fearless, optimistic, happy-go-lucky, and ambitious.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts. As the series progresses, Snape's character becomes more layered and enigmatic.
The Mythology Behind the White Stag
Despite the broad spectrum of beliefs, the stag is consistently symbolic for a number of themes such as purity - with the unusual white coat symbolising an unwavering innocence. The appearance of the stag is also synonymous with the delivery of a message or great change.
In Arthurian legend, the white stag is an animal that can never be caught and represents the quest for spiritual knowledge. A white stage was spotted on the west coast of the Highlands in 2008 with exact location of the beast kept secret to protect it from hunters.
In Celtic traditions, white stags represent messengers from the afterlife. Arthurian legend has it that the creature can never be caught -- King Arthur's pursuit of the animal represents mankind's spiritual quest. It is also said that for those who set eyes on the animal, a momentous moment is near.
The Malfoys are related to the Black family through Narcissa (a first cousin of Sirius Black, Harry's godfather), which makes Draco a nephew of both Bellatrix Lestrange and Andromeda Tonks. Draco is also Nymphadora Tonks' first cousin through their mothers.
Sirius's early life proved unhappy; he had come to hate most of his relatives, in particular his mother. He rejected his family's pure-blood elitism and reverence for the Dark Arts. At Hogwarts, rather than be sorted into Slytherin like the rest of his family, Sirius was placed in Gryffindor.
At the end of GOF only a handful of people even know that Sirius is an animagus, let alone his loveable big doggie form. But by the beginning of OOTP we have Lucius Malfoy able to "recognize" Sirius by seeing the large black dog with Harry. So we're left with a good mystery.
For the Potter uninitiated, “always” is how Snape explains to Dumbledore in the final book why his Patronus takes the same shape as the one belonging to his long-lost love: Harry Potter's mother, Lily.
This nuance was lost on Lord Voldemort, who wrongly assumed Severus Snape held the Elder Wand because he was Dumbledore's killer, when in reality Draco had disarmed Dumbledore before Snape arrived on the scene, making Malfoy the wand's true new owner.
While Dumbledore said he would protect the Potters, it was on the condition that Snape now worked for him as a double agent. Snape's love for Lily ran so deep that he agreed. When she was still murdered, he reluctantly decided that her death would not be in vain, and that he would protect her son.
"The first thing Snape asks Harry is "Potter! What would I get if I added powdered root of asphodel to an infusion of wormwood?" According to Victorian Flower Language, asphodel is a type of lily meaning 'My regrets follow you to the grave' and wormwood means 'absence' and also typically symbolised bitter sorrow.
Severus Snape is one of the most divisive characters in the entire "Harry Potter" series. He was a double agent, so many character details were kept a secret. His mother was a witch and his father was a Muggle, leading to the moniker "The Half-Blood Prince."
Knowing that Snape has been on the Dumbledore's side for all seven of the Harry Potter books reveals him as an extremely brave man and a truly skilled spy. Snape has had to face and deceive the terrifying Lord Voldemort constantly.
