Princess is a dog owned by Hazel (formerly Andrea Tate, Wendy Posner, and Meena Jutla).
Princess was dumped in a carpark before being found and rescued by Emmerdale Veterinary Surgery. When vet Jamie Tate tells his daughter Millie that Dawn Taylor is his girlfriend, Millie says she will love Dawn if they let her have Princess. Jamie tells Millie not to tell her mother about Princess, as he will and when he tells her she reacts badly saying that he is trying to buy his daughter. However the next day Jamie sees Andrea in the village walking Princess, Andrea has now completely changed her opinion on Princess, naming her Princess Sparkle Party the Mermaid and says that Princess shall live with her and Millie in Dale View.
In June 2021 while up at Home Farm with Andrea, Princess poops in Gabby Thomas' designer handbag. Later that month, Princess is tied up outside while Andrea, her boyfriend Charles Anderson and Millie pack for their holiday. Meena Jutla who wants to split Charles and Andrea up lures Princess into Andrea's car and closes the door. Princess is in the car for a longtime before passer-by David Metcalfe notices her, gets her out, then Charles arrives and rushes her to the vet's. Vet Paddy Dingle informs the couple that Princess is suffering from heatstroke and to never leave a dog in the car on a hot day. Meena sees Charles in The Woolpack and informs him this is the second incident Andrea has had with a dog as in January 2020 Andrea drove over the Sharma family dog Tip and buried him in the woods. Princess later makes a full recovery.
After Andrea's death, Millie moves away with her grandmother and it is decided Wendy Posner will keep Princess at Dale View.
In November 2021, Wendy struggles with looking after Princess, so Meena offers to take her.
In December 2021, Meena and Princess attend an Emmerwatch meeting at Café Main Street, when the door is left open Princess runs out and escapes so a search party is formed, Meenas boyfriend Billy Fletcher then finds her wandering the roads and brings her back to Meena.
In January 2022, after Meena goes on the run, Wendy becomes the owner of Princess again. In September when Millie returns to Emmerdale, Wendy lets her look after Princess at Home Farm, as she helps her settle back into living with her granny Kim. When Millie leaves Home Farm to live with her other Grandma, Hazel, Millie is allowed to take Princess with her, despite Hazel's allergy.
