It was challenging for the dogs to get on and off the trains. Wiki fell trying to jump from the train to the platform in Lisbon. Before I could react and put the bags down, a guy came out of nowhere and jumped down to save him. Brian went down after him as well. They were both able to get Wiki back on the platform. No one (including Wiki) was hurt. The train didn't move or anything bad happen. Just lucky Wiki and anyone else wasn't hurt. Poor Wik Wik.
