To find a nursing dog, the Beijing Zoo ran a want ad in a Beijing newspaper. The rejected panda baby soon had a surrogate mother dog. Between the ages of 12 months and 18 months, a panda cub will gain nearly 100 pounds and grow the strong teeth it needs to eat bamboo. When a panda is about 18 months old, it is ready to be on its own. At this time it will leave its mother to make a home for itself alone.
Pandas spend most of their time alone.
They really don't have much time to socialize, because in the wild these slow-moving animals spend about 14 hours a day eating bamboo.
