I know pet jails is a real thing cause I can remember that programme from a few years ago where pit bulls in the UK got seized by police and taken to pet jail while the vet temprament tested them, the outcome was they was returned to the owner, but they had to be muzzled at all times while out and about and they had to be neutered or spayed (the pit bulls, not the owner!)
it was when the dangerous dogs act got made into a thing, I know I didnt make the dangerous dogs act up or at least i don't think i made it up, i better look it up once i got this posted
edit: i did not make the dangerous dogs act up, heres the evidance that i did not make it up:
Dangerous Dogs Act 1991
its a goverment website, not a website i made, i wouldnt know how to make a website, before they accuse me of making it up
