They got a puppy at the start of lockdown. The poor thing is out in the garden alone in all weathers with only a towel and some water until recently when they made a small kennel. It cries all hours of the day from 6-7am onwards. Our main concern is the puppies welfare as it’s clearly distressed. My husband went round the other morning as we wanted to be upfront and just asked to make sure they didn’t leave the dog out for extended periods of time and it is waking us and our children up. They apologised then this morning we received this. They clearly like letters as they also wrote us an anonymous letter about some of our recycling blowing onto the street but we have ring doorbell and saw it was them!
What do I do from here? Leave it? Reply via a letter seen as that’s the way he likes to speak clearly?
