First and foremost, obviously this is an horrific tragedy for all concerned - walker, her family, witnesses, owners of the dogs.
How many dogs would a responsible dog walker take? I've been in our local park and seen 10+, with the walker having absolutely no control. Obviously this isn't responsible but makes it financially manageable for both walker and owner I'm guessing?
Agree it may make it more financially viable for the owner. It makes it absolutely 'easy money' to a ridiculous level for irresponsible idiot dog walkers, when you multiply what the owners are paying.
I am always amazed that anyone will send their dogs out for pack walks with dog walkers, even at four dogs from different households to a walker, unless it is in a private field. They could be the most responsible walker in the world, with excellent control of their charges - but that does not take in to account external influences, particularly other dogs.
On the odd occasion I need to use a dog walker, they take my dogs only. Usually this is when I'm in the house, but snowed under with work, but I certainly know they are on their own and walking from my house, not throwing my dogs in a van with loads of others. On the odd occasion I'm not at home, my Ring doorbell confirms the same.
I feel very sorry for the owners of these dogs, I can't imagine how I'd feel if one were mine and never being sure what part they'd played in a tragedy born of irresponsible behaviour from the walker, who has paid the ultimate price for it.
Oh, and I also don't think there is any racism involved in the focus on the Leonberger's owner. Presumably no-one forced her to show her irresponsible dog ownership on national TV, it just makes her a very easy target now.
