You are the one comparing what a dog who does what a dog is trained to do with what a Veteran does. And you don’t see a problem with that.
This play on words is just not even talking about what is real with these dogs.
I spent a lot of years in the employee of uncle sam with a dog tied to my arm. There were a couple of times I know they saved my ass and several more when they kept me from harms way...
Use whatever words you like but the dogs saved lives and still do.
For that they have a very high value to those of us who are still alive because of them.
