Sorry for my bad english: Russians placed TNT on dogs, and trained them to run toward the tank..... They used a fuse to lit a explosives..... That is cool AT sollution :)
Only problem is that dog cannot see the difference between russian and german tanks, althought they have been trained on t34 tanks ;) , so it wasnt good sollution, only COOL.....
You can train PTRD Tank Hunter squads, and Guards have Krak Grenades. Additionally, the ZiS-2 AT Gun and various tanks mean there is little need for reusing German equipment or making exlploding dogs.
