If you read the article and not just the title, the majority of the discussion is using dogs for diagnostics of collected samples. They (for that use) would not be around patients like you so wouldn’t trigger your allergies.

But for those applications, you would probably prefer giant pouched rats that are much cheaper to train and keep.

If they work as well or better for the purpose, then sure.

Sure, I get the allergies argument, especially if the reaction is a deadly one. It’s a good reason to avoid dogs. I have an allergy too, although not to dogs. It’s not EpiPen level, but I do keep a bottle of Benadryl handy at all times. I totally get the life or death vibe.

But calling dogs killers because one is allergic to them is a bit disingenuous no? People are allergic to many things. It’s not the thing that’s the problem, rather the individual body’s overreaction in the presence of the thing. The problem is with the body, not the allergen, wouldn’t you agree?
