IMO it’s all about the dog and the owner. I know someone with a gigantic malamute who I am confident enough in that I’d send them to the White House with it. At the same time I know people with pugs who I wouldn’t trust in an empty field.

That being said, anyone who relies on the presence of a poorly trained dog for their well being is delusional and detracting from actual service dogs while putting a bandaid on their actual condition. If you need a poorly trained and poorly kept chihuahua in your shopping cart in order to navigate hannaford you need more help than your chihuahua can provide.
