My mum was a kid in the war, she told me 2 stories,
My aunt rehomed a dog from a shelter, one day a man in uniform (soldier) shouted out a name, the dog responded by running to him, it was the man who gave him up.
The other is, her brother was born in 1945, the midwife would not have dogs in the house, so her mum had them "put to sleep", the day he was born, a different midwife turned up to the birth.
