Thylacine as pet: remarkably tractable, docile, and affectionate - and, in some respects, superior to the dog. One of these reasons is that the thylacine acquiesces to others without protest - they do not engage in power struggles.
I don’t wanna get all bigfoot on you, but I think if you did some research you would agree that there is a small relic population alive today - but the species is still extinct.

“Captive thylacines kept on dog chains on farms or in the bush frequently gave a short low growl or started ‘grunting’ to warn of a distantly approaching stranger - an ability for which they were prized and held to be markedly superior to domestic dogs. These pet thylacines, while tolerant of sympathetic or non-interfering humans with whom they lived, would nevertheless growl aggressively at strangers in their immediate presence.”
”it is these same, or at least very similar, social and developmental characteristics that make the placental wolf/domestic dog such an effective and rewarding companion animal to our own species. It should come as no surprise that, early on in European contact with the species, people started raising thylacines and keeping them in captivity. These thylacine-human relationships proved so rewarding that keeping thylacines in captivity was persisted with, amongst a small sub-population of Tasmanians, until the population dynamics of the species rendered it no longer possible. “
”Mr William Cotton [snr] came into the town of Swansea leading a Tasmanian Tiger, most people at the time were scared of the animal, and were amazed to see a person doing such a thing. … Cotton … had snares set about 4 miles [6.4 km] west of Swansea … and … one morning found he had caught a tiger. … After some consideration he cut a short pole about five feet long, and to the end attached a piece of rope … and with a noose made on the end slipped it over the tigers neck, held him at bay, cut the snare, and set of [sic] to Swansea leading the tiger with him. He had great trouble to get the animal to travel, but after going a few hundred yards the animal started to act just like as if it was a dog, and followed along beside him for the rest of the way to Swansea with the lease of trouble“
”Newly caught captives soon gave up aggresive responses towards their primary care-giver, accepting the parameters of the power relationship newly entered into: ‘my grandfather caught … them and took them … down to Hobart into the zoo. … He took one home and he … had him tied up on a dog-chain and he used to feed him rabbits, in an old blacksmith’s shop. And he walked in one night and thought he was back from him - struck a match before he was going to give him the rabbit, like - and he was standing up against the old tiger. He’d walked further over towards him than he’d thought, and the old tiger’s standing there, wagging his tail, he said, looking up at him, waiting for him to give him the rabbit.’”
Sadly, I can’t have one as a pet.
