Bit of background - PIL are nice people,but not particularly involved in our life,as in,they have 3 grandchildren but only see them on special occasions & don't make contact with them in between.We also have a child with SN(if that's relevant?),& we both work.
They only live a few miles away and are financially well off.
They have a young cocker spaniel(we have 2 very elderly dogs),this dog usually goes to stay with BIL and SIL,as they too have a young spaniel type dog.SIL is battling cancer.
FIL is adamant that he will NOT put the dog in kennels,as he thinks 'kennels ruin dogs'.So he has asked if we will have the dog for 3 weeks while they go on holiday.
I have said 'No',but I know this will cause trouble within the family.
How do I stick to my guns without causing trouble?
