The dog in question would be at least 210 dog years old by now. That National Lampoon ad was at least 30 years ago.
I am sure that he is already in dog heaven, or perhaps has been reincarnated as some higher life form.
I have a question about karma, though.
Suppose you have been reincarnated as a banana slug.
How does a banana slug demonstrate that he has lived an exemplary life as a banana slug? In what way would an evil banana slug's behavior differ from that of a noble banana slug?
How does Braman know that a banana slug is meditating, as opposed to planning an vicious attack on a fellow slug?
