Did we make it?

Yes, we did.

Did anyone see Pepa wiggling about in her bag?

Yes, they did.

Was it the driver?

No it wasn't, and that's the important thing.

It was a nervy five minute wait in the queue, especially when the driver opened the doors and everyone moved forward. Pepa squirmed about in the bag, but I managed to sneak her past the driver and shot up the back

As it was 3pm the bus was half empty so no one saw when I opened the bag up so Pepa could poke her head out and get some air. It was hot and stuffy on the bus and I was glad it was only for two and a half hours. At Huelva the driver cut off the air con so the bus boiled up, as did Pepa.

So who did see her?
Two American women had spotted her in the queue at Plaza de Armas.
'We knew you had a doggy in there,' said one as Pepa stumbled out the bag in Ayamonte. 'It was wiggling the whole time in the queue.'
So there you go, if you need to transport your dog on a bus then it's possible. I don't know why they don't allow them anyway, I'd happily pay an extra charge.
It was definitely worth the risk. Watching Pepa run about the beach and play in the sea was great fun. She loved it, but is now depressed to be back in the oven flat in Seville.
I'm off on holiday now to Fuerteventura so won't be writing until the middle of September, hopefully with some stories when I get back.
