My name is Nikko!

Needs special diet, Biome.
Fights other female dogs. Barks at other dogs. Fights with her half-sister, my other Shar-pei, sometimes over good or water.
Good watchdog. Barks if someone goes past.
Used to having a pet cat and rat in the house.
Likes to roll in the grass, chew on sticks, and run around.
Nervous around toddlers.
About 5 years old.
Snapped at my one-year-old granddaughter when the toddler tried to touch her as the dog was lying on the sofa.
She was my daughter, son-in-law, and grandchildren's dog from age 4 months. My daughter died in a car accident in 2022, and Nikko came to live with me, because my son-in-law said it was too much. I already had Nikko's half-sister, Sylvie, who was actually my grown son's dog who was left at my house when he moved out. Nikko has started several fights with Sylvie over the last few years. My son and daughter in law and 13 month old granddaughter are living with me temporarily , and I am afraid that Nikko might bite the grandchild.
