[hamlet]

Hi I'm new here, I have a 10 month old yorkie called Hamelt. We've had him since he was 8 weeks old and only recently has he found his voice and starts barking when we leave the house.
He don't bark if we are home and don't bark if someone knocks on the door.
I took him out all day yesterday and he was very tired so I left him for no more than 10 mins while I went to the shop. By the time I arrive back he was not barking. I had a hand written letter by one of neighbours saying That i need to stop leaving my dog alone, he barks for hours at a time and said he barks all night and that they are reporting me.
He's never barked at night we are all home by 4pm. We got to work/school at 8.30am my husband pops in at 2pm to walk him and me and the children are back by 4pm, plus my husband only works 3 days a week so is home with him for the rest of the time.

Is there anything I can do that will stop Hamlet barking while we do go out? As I don't want to upset my neighbours or have my dog taken away, he's very much loved and the most sweetest little dog you'll meet. I wish the anonymous neighbour would of spoken to me instead of sending a nasty letter, I could of apologised and explain he is only a puppy and that we will try and solve the problem.

Any advice would be much appreciated.
