Regarding How can I tell whether my dog was euthanized in a painful fashion? , the asker stated they went to PetSmart (a pet supply and in-house veterinarian chain) to handle their dog's euthanasia. The verbiage used read as though he had to justify using PetSmart rather than a standalone veterinarian, and could infer that the service received may have been less competent than at, say, a standalone.
I am not defending the company practices, but I generalized the references in an edit, rather than leave them in. If the asker has a problem with the company, that is their problem; implications of slight that aren't relevant to the question should be removed.
Was this the correct course of action?
