I too have had a problem with Millets in the past and have tended to avoid them as a matter of principle. At the time they were selling a reasonably good 'expedition' tent at a sensible price, but not being the usual cheap 'festival' product it had to be ordered. I did so, and they called me to tell me it had arrived, leaving an answerphone message. I made my way in a couple of days later, only to be told by the manager that because I hadn't returned their call (they hadn't asked me to) they'd sold it to someone else. I was not a happy bunny, which I think the manager understood by the time I left.
I boycotted Millets for some time later and still tend to use them as a last resort, although I do think that they provide satisfactory gear for most walking conditions at a reasonable price.
I wasn't aware though that they were in any trouble? After hearing about your issue with your canine companion, and my own experience with them, perhaps they need to address staff training?
