Who is your childhood animal hero?

I'd say Krypto. Do you remember him at all? He was Superman's dog and he helped And saved Superman so many times. I also liked Boomer. He was sort of a mixed breed dog will help different people he met along this way. He had a TV show from 1980 to 1982. There is also this other dog. He was a St. Bernard but I can't seem to recall his name at all! Of course I like Lassie too but did you know that there were several Lassies? They all looked alike and acted as doubles when the real one was "tired".
