No, never felt that strongly about a pet, though I did have some affection for them when I was younger (cats especially).
Nothing against you, but dog owners who feel this way bug me. If you have a little kid, they come up to you with their dog like it's the best thing in the world (their dog and your kid). Except, my kid was scared of dogs so I had to keep waving them off. One time the kids were drinking from a fountain, and some stupid dog owner had their dog drink out of it, and thought that was just peachy. Again kids and dogs, I thought it was disgusting to have a dog drink from a fountain that was meant for people. These kind of dog owners take their animals as members of their family, but they aren't. They're a different species.
Here's a story about this. I was going across the street once when some stupid dog ran towards me and got hit. The owner freaked out, and was in her back yard wailing and crying. The driver (of an Ambulance for gods sake) was crying and freaking out too. This is a person who sees tragedy all the time. I'm the only one who has the presence of mind to pick the damn thing up, piss, blood and all, and carry him to the shade. I contact a neighbor to take the animal to a Vet to be taken care of.
The irony was that I was very likely the only vegan there. Everybody else looked like meat eaters, and very probably were. I don't live off of the killing of other mammals, while the rest of them kill (or have killed) some tens or hundreds of animals every year to feed their faces. But now, when animal death is in front of them (and it's a stupid little dog) they all go to pieces. I'm the one who isn't killing animals, and I actually take care of the beast (even though I was disgusted with how stupid it was).
Postscript, due to my actions the animal made it through with a few stitches.
