I did ask her to remove the dog. She kind of blinked at me in surprise and then did so but two minutes later went back to her phone and let it start roaming again.
At that point I just stood up and grabbed my luggage, then I asked her to move her dog -which was now blocking the aisle - out of my way so I could walk by. It seems she expected me to walk over her dog while carrying luggage?? But anyway, I found a carriage with no dogs. Luckily it wasn’t a massively busy train so I didn’t have to stick to my reserved seats.
I also emailed the train company and asked them to consider having designated dog friendly carriages like they do in Finland and other countries. They said they’ll consider it but I doubt it.
But really if they allow dogs on trains they need to have enough staff to be able to enforce rules are followed like being kept under the seats, not on the seats and not in the the aisle or other peoples seating area. And perhaps they could add signs around the train reminding dog owners. That incident happened on my journey home from my friends, but on the way out there was actually another dog in my carriage. This one was completely off leash walking up and down the aisle in a crowded train. I didn’t want to start walking up and down the train with an unsupervised dog in search of of the owner. It’s just not my job. It’s not really fair customers having to confront other passengers especially as some people can be very aggressive and hostile.
Thousands of people attend NHS hospitals for dog bites every year. I’ve personally witnessed dogs be aggressive to other people and heard people tell me various stories including ones I’ve read on here which include stuff like their partners dogs growling at their children or their neighbours dog snarling each time they go out in the garden so while I don’t think most dogs are, I don’t think aggressive dogs are all that rare.
It doesn’t happen every day granted and the last time it happened to me was October on the coastal walk but then as I said I don’t really interact with dogs (except the dogs of a few trusted friends which are lovely and calm) and give most a wide berth.
