They are worried that with his fame, somoene will want him and then lose interest- the easter kitten syndrome-so they are screening for people who don't care much about about celebrity or football. That said, I will also say that in general, dogs tend to be much more autonomous and less neurotic here. It's common for dogs to be wild, and I've never seen one that was the picture of dejection (like the roming, flea ridden, hungry dogs in other countries). Here a dog trotting around probably won't even take you up on bite of food, unless it's something really worthwhile. People feed them, and rarely mistreat them. I have seen:
1) Dogs accumulating inside, yes, inside the National Cathedral, where a nun then came and emptied a bag of kibble onto the floor under all that stained glass.
2) A dog get on a train at a stop, meander around the aisle, then sort of boredly position himself at a door, then get off at the next stop as though it were his daily commute.
3) A neighbor lady angry because homeless people were 'stealing' the blankets she wrapped around dogs in the plaza during a cold snap.
Also-they have a (free) national heath care system with hospitals and this includes a veterinary hospital. You saw in the video that this dog interrumpted a very important game for 5 minutes before the video started, pooped the pitch, ran about and there was no violent dog pound man come in with that horrible lasso on a stick thing they use, and no horrible, violent shelter to cage him into alongside other traumatized, lonely dogs; they were patient with him, the crowd loving him, and would not grab him roughly. Only when he let himself be taken was he taken.
