Neighbors had a “Rex.” Good dog.
The neighbors had a German Shepherd named King, which is sort of close.
Never met any Lassies, though they must exist. No Rin Tin Tins either, not even a Rinty.
If someone started a sister thread, the feline equivalents would have to be Puss, Princess, or Fluffy.
Does he know?
I had a cat named Cat. He came with the name of Sugar Frosted Flakes (because he was tiger striped), but I refused to call him that.
The shelter called my current cat Churchill. I changed it to Jack.
Who? The Shadow?
He knows…
I’ve known at least three people with iguanas. Every last one named Iggy, although at least one had a last name (Pop).
Not quite in the same class, but when I got my harlequin Dane at 11 months, the family had named him (with the kids having outsized votes, obviously) “Harlie.” I was limited in what I could change it to but found a much more acceptable name with a similar sound.
My brother had a dog named Rover. She was a nice dog
Wasn’t “Fido” a Roman thing? Since it means “Loyal” in Latin? I assumed it was no longer common because we don’t speak Latin 
Rover - similar; I think of a hunter or a shepherd naming their dog Rover. Since most of the dogs we all likely deal with are true pets, not working dogs, we don’t encounter situations where dogs are named based on what they do for work.

My wife’s first dog (she was 3) was a border collie named Lassie.
My grandmother had a dog named Spot (I think he had a single black spot on his back).
My first rabbit was Bunny Bunny.
I had a Collie named Lassie when I was a kid. I named her when I was 5, so…
Fido and Rover used to be common dog names, a long time ago.
There are trends in pet names. People used to name dogs after physical characteristics, like Spot and Blackie, but the current trend is to use human names. I read a very interesting and well-researched article on the trends over time awhile ago but can’t find it to my regret.
I think for Boston Terriers, the cliche names are Buster and Buddy.
So many are named this!
Lots of Princesses and Fluffys. Little girls name cats. Little girls name dogs too, but not Rover or Fido.
I’ve never encountered dogs with the names the OP cites in real life. I have run across dogs named “Fido” in books (which were pre-cartoon-era, so they weren’t getting them from there). The name means “I am faithful” in Latin, so it’s appropriate for a dog. Not many people study Latin these days, so it’s sorta not appropriate anymore. Everyone would just think you were copying a cartoon.
NO! :eek: You can’t change cat names! It will bring you seven years of bad luck!
(Or is that boats?)
I’ve never met a dog with one of those names. I’d imagine it would be like meeting a person whose actual name is “John Doe.”
I see a lot of dogs with old lady names, which have probably come back around to being little girl names again. Sadie and Daisy are popular.
Our neighbor when I was a kid (circa mid-70s, small town) had a great Irish Setter named Rex.
