Just that really.
I had invited a relative to stay with us for a family wedding. He accepted but then told me his dog isn't housetrained. To be clear, we have dogs and are normally happy to have family bring their pets too but our dogs are all fully trained.
All our carpets are new - less than a month old - and the house is open plan so it's impossible to contain his dog while he is here. I've said he can't bring the dog but it looks like that will mean he misses the wedding so I feel guilty.
