I’ve noticed that many more courses for dog walkers/trainers/behaviourist include a module on how to deal with people who have lost their dog. I think it’s necessary as (it’s not only my opinion) many trainers think the hardest part of their job is dealing with the owners, not the dogs.
I’m lucky enough to have a friend who’s a bereavement counsellor. But even with all I know and all I’ve learnt and all the mental and physical preparations I have slept 7 hours in 6 days, forced myself to eat 5 meals in a week and was hiding in the toilet crying a few times. Ardbeg was neither my first, nor my only dog and because of the loss of some of the closest people in my life I know (in theory) how to manage. So, yes, I do think it’s important for a good dog trainer or behaviourist to understand how strong the human/dog bond can be.
And without this little lady in the photos, I wouldn’t cope well at all.
