If you have read any of my other posts you'll know I've been concerned that Sherlock has been making some noise whilst we are out at work. Well at 5.38 this morning it was confirmed.
As some of you are aware Sherlock is nearly 5 months old now and has been unwell recently. This has meant his Poo times have been inconsistent, and so he has been waking up earlier than usually. Most days it has been between 6:30 and 7:00, but today as he needed a poo he woke up at 5:30. Like a mother is tuned in to a new born babies cries, I am also tuned into Sherlock

and so the second he starts whining I'm up straight away switch the hall light on, which usually stops him immediately, I then trot off downstairs to let him out etc. he can only be making noise for about 5-10 seconds. This has been the routine since we got him, although it is usually an hour or so later than the 5:30 wake up call it was this morning, and before he was poorly there we're an increasing number of days where I had to wake him up.
This morning because it was so early I put him back in his crate, I've had to do this a handful of times and it has always been fine, he goes straight off to sleep. However this morning he started whining/howling. I thought I'd try leaving him, but in the end had no choice as 30 seconds later there was huge continuous banging on the bedroom wall and a shout of 'will you shut that f£&?!ing dog up!'

So he is now asleep next to me in bed, which we have been really keen to avoid, and which no doubt my partner will go mad about when he gets back from his night shift shortly.
So as I sit here on the edge of tears, with a million and one concerns flying around my head, I am wondering how to approach this. I can only assume he has been barking during the day, as there's no actual evidence that he has been doing, his crate is not messed up, he is quiet when I close the door behind me and quiet as I turn the key to open it, but I am guessing he must have been to warrant this reaction from her (the neighbour).
I'm really at a loss as to what to do, she's not a reasonable women and so a polite note, conversation is unlikely to work. I mean someone who shouts that at 5:40 in the morning with their children next door is not in my opinion someone who I am going to be able to have a mature conversation with. I can empathise with her if Sherlock has been making lots of noise, but in the mornings it is almost always a maximum of 5-10 seconds before we see to him, for the very reason that I am conscious of her and the children. Also, I am unhappy that she has not approached me sooner rather than let this happen, she saw me in the street the other day and could have said something then but instead ignored me (now I know why). We introduced him the day after we got,him, and apologised about any noise there might have been, but I guess the he was cute puppy (he still is to me) and so they said they didn't mind, and had really heard anything anyway.
I'm really sorry about the length of this MSG, but I wanted to give you all the details in the hope that someone would have some advice about how to move forward, as I really don't know what we can do. Sherlock already goes to doggy day care twice a week, and has a dog walker twice a day or goes to the my partners parents, on the days when both myself and my partner are working, so he is rarely alone.
Any help or advice at all would be greatly appreciated

Thanks
