Yeah, the Soviets never had much of a good track record with dogs... Sending them into space in non-pressurized capsules... Strapping bombs to them and sending them to look for food under German tanks... That last one is hilarious in the most tragic way possible as they trained them with soviet tanks. Dogs, being more intelligent than the Russians gave them credit, saw the German tanks and then saw the Soviet tanks and thought, "I don't recognize those ones but those look like the ones that always have food under them."
Every dog they actually tried to use in battle they had to shoot. That's the tragic part. The funny part is the people who came up with the idea were idiots.
