I am (as you can guess) a dog owner and i hope, a good one with regards to behavoir and picking up.
However dogs don't behave as humans do and sometimes we put them in situations that are confusing and upsetting for them.
Too many people, too much noise and lots of temptations.
You have to know your dog but personally they should stay at home where they are safe and usually happier. Dog/house sitters have always worked well for me.
