This is such a sad thing to happen & people don't understand that dogs are just dogs. They still have that flight or fight instinct. Bronson was the nicest Dachshund in the world until he was attacked by a mastiff at a show, I still like mstiffs, this was just a bad one. He now will fight before he gets attacked.
He also loves people very much but again, on a night where there was a car crash & I did lots of yelling to get people out of the road of a run-away driverless car, he bit a lady on the leg who got too close to "his children", my youngest 2.
The same thing happened on a cold windy day where someone just wandered into my yard with a hammer to fix my roof without letting me know they were there & surprised my dogs. Lucky he had a hammer because he also got bitten on the leg after I yelled at him to stay out until I locked up Bronsons grandmother who hated men but loved any other stranger.
When I take my dogs to show, they can be very nasty to anyone or anything if there is a bitch on season too. If they are scared or someone rushes at them, it can worry them. These dogs are mixing with strange dogs and people all the time but sometimes another dog can look at them with intent & the hackles go up.
I now have electric fences all around the top & bottom of my fences just to keep them from getting out. My gates are locked with padlocks & chains very tightly.
Dachshunds are cute & small but my smallest mini smooth hair I have at 4.5kgs can kill a half grown lamb & my biggest standard longhair (Bronson pictured here) can kill a fully grown sheep on his own. I have lost too many rats, mice, rabbits & now lambs not to have them in electric fences with solar power as they know when the mains power goes out. Cute & cuddly but still have that instinct to kill.
I love bullies & my friend breeds mini bullies, they really are great natured but like staffies, they may not start a fight but they sure will finish it. I had staffies myslelf & this is so true even to the nices dog. My staffie was at the bottom of the pecking order in my yard & I had 7 mini longhair dachshund & 6 pups.
Get a hold of those images from the train station if you can just to see what happened there. You sound like you are very strong & you need to be with dogs you really have to be. I also lock my guys up in pens now when i go out as I have a very nasty man living next door & I have come home to unlocked gates in the past. I'm now buying 300 acres to build my dogs a home where no one can hurt them or bother them. I love my dogs & you keep loving yours & doing the best by them.
Good luck
