TenForward: Where Every Vulcan Knows Your Name

One of the reasons that cats tend to live longer than dogs there's a lot of cats are just general muggies, they basically bread themselves.

You can always tell something funky has happened when there's a litter of black and white cats and then a random orange one in the mix. There's always some throwback to an earlier ancestor. But that basically never happens in dogs.

That's depressing

Yeah, most purebred dogs have way shorter Lifespans than random mixed dogs

If I’d met any Soong, I’d have made sure my dog lived forever. Immortal Porthos confirmed.

The pattern buffer was corrupted during transport, which explains the physiological differences.

Scotty: How do you think I wound up here? Had a little debate with my instructor on relativistic physics and how it pertains to subspace travel. He seemed to think that the range of transporting something like a... like a grapefruit was limited to about 100 miles. I told him that I could not only beam a grapefruit from one planet to the adjacent planet in the same system - which is easy, by the way - I could do it with a life form. So, I tested it out on Admiral Archer's prized beagle.

Kirk: Wait, I know that dog. What happened to it?

Scotty: I'll tell you when it reappears. Ahem. I don't know, I do feel guilty about that.

Scotty in the 2009 Star Trek movie explaining how he wound up in an especially remote posting.

In the reboot movie.

Reboot movie. He was improving transporter tech, put an unnamed cougharchercough Admiral's beagle into the system to test it and it went away tae fuck. Which is why he's been assigned to the bumfuck artic station in the movie.

Yes, and Porthos existed before the divergence, so it still would have been the same dog in that timeline.
