Without knowing the adults in question, their dog related experience, their common sense levels or whether they get drunk, lairy, or stroppy at Christmas.... no, no I wouldn't.
I've been doing this job over 20 years. In that time the stupidity I have seen from adults, surrounding dogs is absolutely monumental.
And that is adults who chose a dog, have had multiple dogs, live with the dog in question full time.
THe things I have seen people do at parties, in the pub etc, to dogs they do not know are again, astonishing in their stupidity.
Taunting and teasing with food, assuming the dog understands rules they've imposed in their head on a dog that is not theirs in a home that is also not theirs, so , smacking the dog in the face for getting on the sofa (where the sofa is empty, and the dog permitted to do that), chasing the dog downstairs, yelling and roaring... again, in the dogs home, where the dog is allowed upstairs...
Leaving food where the dog can get it, despite being told multiple times that food left unattended would be eaten by the dog, not to put drinks on the floor as the dog will knock them over/drink them, feeding the dog from the table when told not to do so.
Not leaving the dog alone in its own bed or crate - I recall one bbq party I was at (back when I did parties!) I found a drunk adult, on his hands and knees, head in the dogs crate with a fucking chicken drumstick in his mouth, growling at the dog. When I asked what the very fuck he was doing, he pissedly told me he was showing the dog he was boss - luckily for him, the poor dog was terrified and trying to shrink or vanish, because she could have rearranged his face very easily.
He said he got the idea from TV that you have to own the space so the dog doesn't take over (thankyou Cesar fucking Milan, your gift to dog training just keeps on fucking giving!)... wasn't his fucking dog, wasn't his house, he wasn't even an invited guest but a plus one and he'd never met the dog before in his life!
In my experience, in any family gathering there will be at LEAST one adult who will listen to all the dog related rules and then intentionally break them because 'they know better', and often these people will have never owned a fucking dog in their life.
In my family, that's my Dad. He doesn't meet my dogs any more.
