No. there are many that only have a small central nervous system . Single celled organisms are a prime example as are some microscopic marine life. All mammals have a brain however.

Though the animals have less brain, i mean in size, but all do have brain.
We are also social Animal, but the difference is that we are little smarter and intelligent than those animals.
