Oh yes, I daresay she LOVED having a bath and her nails painted 
Why publicise such a personal loss? Oh of course, its the daily mail.
It is nice that she was able to make the most difficult decision in good time, always better imo but not everyone has that luxury and their pets deteriorate quickly to a point where the best thing for them is to be pts at home or in surgery at short notice.
The best thing people can do for their pets is maintain normality, lots of cuddles and try not to let them see you upset. If you can be with them at the end then that is good too.
I work in a vets and owner grief never gets easier to deal with and we often have to take some time out after pts. It is only something we can do because we know its the kindest thing.
