I know you love your dog and find it precious, but people who come to your home may not love your dog. They may even find it...brace yourself...repulsive. If your dog can't stay off of your visitors, please place it out of site.
Signs your guests may find your pet's advances offensive:
They recoil and/or shudder when it approaches
They don't pet your pet, or look it in the eye
They mutter 'isn't that swell' when the pet jumps into their lap
They didn't arrive covered in their own pet's hair
Just some thoughts for those blinded by dog-love.
