PIL's dog has developed kidney failure. It's currently on a variety of medication and painkillers, but the vet has told PIL's that the dog probably won't last much longer.
PIL's are doing their best to make sure dog is comfortable, but are currently undecided about whether to take him to the vet to be put down. Their view on this seems to change from day to day.
Anyway, today, DH was talking to his sister on the phone. Apparently BIL went round to PIL's house today, when PIL's were out, and has dug a grave for the dog in the back garden. It wasn't clear whether BIL had discussed this with PIL's in advance or not.
AIBU to think that this is a bit premature on BIL's part? The dog's still alive, after all.
