Who ridicules service dog handlers in the first place? Do you hear a lot of people complaining about getting ridiculed? I've never heard of anyone getting ridiculed for feeding any kind of food to their dog, be it a SD or a pet.
If this has to do with the training organization telling the handler what to feed their dog...I don't see a problem with it. They put a lot of time and effort into training the dog, gave it to that person for free, and if they believe kibble is the better food then they should be listened to.
In the previous thread about service dogs and therapy dogs, you used a couple of organizations as back up for the fact that they don't believe service dogs should do therapy, now you're saying those same organizations don't know what they're talking about when it comes to food and nutrition. I'm confused, should we just pick and choose what we feel like those organizations are "experts" in?
