My parents live 3 hours away and have been to visit us twice in the 4 months since we moved. They have a dog which I love but isn't very well trained at all. She will bark, sometimes run off, is quite fluffy and therefore gets filthy, and howls when she's left home alone. We have a brand new house and so I cannot stand her trailing wet, muddy paws in, up onto the sofa etc etc.
Am I being unreasonable to ask them to leave her at home when they come and stay next?
