Let the dogs to clean the plates

Would you let your dogs to clean the plates?
Once I was invited for lunch at a friend's house, she let her dogs to lick the plates clean after the meal. What is your opinion on this?

Some people never mind their dog linking the plates.On the contrary,they enjoy the process of it.One reason is that they think their pet dogs are clever doing some housework for them.Another reason is that they treat their pet dogs as a member of their family and also good friends.So when they see their pet dogs "share food" with them, they feel happy and friendly.Especially,for those lonely old people,who like their pet dogs licking the plates clean.
However,other people will mind their dog pets doing that,though they like dogs very much.They don't like the saliva.In addition,some of them are sensitive to animals' saliva.For me, i don't like my pet dogs licking the plates.i'm not used to this case.But i like washing pet dogs,"take a shower for them",which is so funny.Unfortunately,my pet dog is "wander all over the world",it won't give me the chance to wash it.

I know a lot of people treat their dogs like babies. Personally I felt it is disgusting. Not sure about the others. The people who let their dogs to lick their own plates definitely feel perfectly fine with it.

I really don't like to see that. We have a friend who feeds his dog from his fork at the table. It's gross, and it puts me off my own food. On top of that, the dog is a complete nuisance when anyone is eating because she expects to be fed from the table. When our Border Collie was alive, we never fed him from the table or let him lick our plates. If there were leftovers that were suitable for him to have, we used to scrape them in his dish when we'd finished our meal.

Ew, no way.

I do let my dog have human food because I make his own using real ingredients instead of buy pre-made stuff from the store. That doesn't mean I want his tongue on my plate, though. Even if I know I'm getting ready to wash it, I think that crosses the line of etiquette and shouldn't be done.
