> What I find just as hard to understand, is what sort of owner allows their dog to be walked by these people?
In my experience round here, the owner that has no idea it's happening :-(
I helped out a dog walker/pet sitter over summer last year - the shpiel is great, she sounds fantastic, everyone thinks she does a brilliant job with their dogs and the dogs get an hour's walk if that's what's paid for, and if they're being boarded at her home, they get 2 or 3 hours' walk a day and live as if they were in their own homes.
The reality? The dogs being walked get half an hour if they're lucky, usually more like 10 or 15 minutes, often with other dogs they are worried about (but because she AHs any grumbles, any hint of unhappiness is hidden by the dog so she thinks they're fine). Dogs end up spending most of the day stuck in the car (and have been left in full sun many a time).
When being boarded, the dogs end up spending a lot of their time in a cage because one of her own dogs is dog aggressive and guards her very badly (I have tried to help with this and with his unhappiness/nervousness generally but she's one of these 'I know about dogs' types and will not listen (despite asking me for advice and acknowledging that I know more about behaviour than her), even though she knows nothing). He is miserable, the boarding dogs are fed up and ignored and the owners none the wiser.
One of them is seriously fed up with her now - from the start this owner has insisted that the walker has his lead handy and that he always has his collar on - she NEVER takes any leads with her at all when walking dogs, lets off dogs that should never be let off, and recently this particular dog was taken home to the waiting owner without his collar on - she was a bit miffed to say the least! Never mind that it's illegal, it's safety - if he had spooked and run off (and he is a nervous dog) there'd be a heck of a lot less chance of getting him back.
That owner is about the only one who knows what goes on - all the others still think she's doing a wonderful job.
