I have 4 chihuahua puppies, born on Christmas eve. 3 girls and 1 boy. Black and tan, and tan. All very social and playful. Pretty much potty trained to the pad. Eating solid foods. Do not have their first shots. Not 100% sure that they are full chihuahua. But they are stinking cute. And healthy, even a little tubby. They like to be held, and rubbed and petted. Use caution around toddlers and babies, they love human attention and get very excited with their paws and their baby teeth. Gets along with other dogs. They are all on a regular schedule and sleep through the night. Two of the girls have small umbilical hernias.
