I have a small contribution to make towards the betting on animals conversation.
It's not anecdotal, it's a real experience story.
Some of you may remember that in my spare time I used to rescue dogs.
All sorts of breeds, usually unwanted animals and dogs for whatever reason (right or wrong) surrendered to the dog pounds around the Irish countryside. There were lots of breeds but predominantly greyhounds. Especially greyhounds that were just past their best and had stopped winning - winning meaning making money for their owners.
Now, a majority of owners were responsible and either looked after these dogs themselves or surrendered them through channels to responsible greyhound centres who either found people to look after them, or fostered them out.
But some didn't do that.... and in a forlorn attempt to make owners responsible for their dogs, Irish Greyhound Racing Authority got all owners to register their dogs. This was done by tatooing the dogs number into their ears and this number went into a ledger when the owner registered it. Nice try, but when the dog stopped winning the poor dogs ears were cut off and the dog put into a pound or usually chained up to the pound gates late at night.
I can't tell you how many greyhounds I took to Sweden to be rehomed as pets.
(Sweden loves dogs from Ireland because Ireland is rabies free so the dogs from here are clean)
The dogs would checked over by a vet, neutered or spayed, a microchip fitted, a one way passport was issued, then a bit of a journey was coordinated and I would meet up at Dublin airport and take 5 or 6 dogs on a plane to Stockholm (Direct or via Riga depending on the flights) where they would be met by their new families and they'd live a happy life.
With little or no ears.
