One common theme is the power dynamic. Usually, the vampire has a lot of power and the pet is in a more submissive position at first. For example, in many stories, the pet has to follow the vampire's rules.
Love and loyalty are also prevalent. The pet may start off as a captive but over time develop deep feelings of loyalty and even love for the vampire. In some novels, this relationship evolves into a romantic one. For instance, in 'The Vampire's Beloved Pet', the two characters' relationship changes from master - pet to lovers as the story progresses. And they have to face many difficulties together, like the vampire's enemies who don't accept their relationship.
The exploration of the supernatural world is another theme. Vampire pet novels often describe the vampire's world, its hierarchy, and the other supernatural creatures in it. The pet gets to experience this strange world, and the readers get to learn about it through the pet's eyes. For example, we might learn about vampire clans, their feuds, and how different types of supernatural powers interact in this world.
One common theme is the forbidden love. Since vampires are often seen as otherworldly and dangerous, a relationship with a human is considered taboo. This adds an element of excitement and danger. For example, in many such novels, the human character is drawn to the vampire's allure despite knowing the potential risks.
The theme of identity is often explored. For example, in 'The Vampire Academy', the dhampirs have to figure out their place in the world between humans and vampires. Also, the idea of immortality and its consequences is common. Vampires are immortal, and they have to deal with things like outliving their loved ones, which is shown in various YA vampire novels. These themes add depth to the stories and make them more than just about vampires biting people.
One of the main themes is the struggle for acceptance. The omega is different in the vampire world, and he has to fight for acceptance both from the vampires and sometimes from his own kind. Also, there is often a theme of redemption. The vampire, who may have a dark past, can find redemption through his relationship with the omega. For example, in some novels, the vampire has killed before, but the love of the omega makes him change his ways.
One common theme is the power of seduction. The vampire seductresses use their charm to manipulate others, whether it's for survival or for their own desires. Another theme is the struggle between their vampiric nature and their humanity. They may have emotions from their human past that conflict with their blood - thirsty vampire side.

Power is also a major theme. In space vampire novels, vampires often have powers that are enhanced or changed in the space environment. They may use these powers to dominate other species or fight for control of space resources. There's also the power struggle between the vampires themselves, especially if there are different factions or clans in the story. And sometimes, the humans in the story try to gain power over the vampires, either through scientific means or by forming alliances with other alien races against them.

Vampires are powerful beings, and this power often plays a role in their relationships, whether it's a dominant - submissive relationship or a struggle for power within a vampire clan.
Love and romance are common. Often, the vampire princess falls in love with a human or another supernatural being, creating a forbidden love story. For example, in many novels, the differences between their worlds make the relationship complicated.
Love and lust are common themes. Female vampires often find themselves in complex relationships, either falling in love with humans or other vampires. Another theme is power. They may be seeking power, either to survive or to dominate in the vampire world. For example, in 'The Vampire Diaries', Katherine uses her vampiric powers to manipulate those around her for her own gain.
