Yes, the second part of your text, "Which had been found as a stray living on the streets of Moscow," is a sentence fragment. A sentence fragment is incomplete and cannot stand alone as a complete sentence. To correct it, you could combine it with the first sentence or rephrase it. For example:

"On November 3, 1957, the Soviet Union sent the first animal into space—a dog named Laika, which had been found as a stray living on the streets of Moscow."
