1960-F19
1K No. 4 (Vostok-1 No. 4) was launched on 1960 Dec 22 using the new 8K72K vehicle with the uprated RO-7 third stage engine replacing the RO-5. The engine's gas generator failed to operate correctly and the spacecraft did not reach orbit. However, the cabin made an emergency landing in Siberia 65 km from Tura between the Ognekte and Yukteken rivers at 63 42N 99 50E; another source gave 63.8N 107E near Tura.) and the two dogs were recovered alive. They failed to eject from the capsule during descent. Apogee was 214 km, range was 3500 km.
The names of the dogs have been reported as Damka and Krasavka,Shutka and Kometa,Zhemchuzhnaya and Zhulka, or Zhul'ka and Al'fa. I believe the latter to be correct.
