Hi

<" noisy, slobbering, germ-ridden shitting machines. "I'm with the dog." >

Describes many humans too...!!!!

The real answer to this dilemma is that the dog should be well trained and be used to having "strange humans" around.
We had had several dogs over the years and all were well trained and caused no problems for guests. The guests were often not as well trained as the dogs...lol.

Cheers
