We have a 16 month old terrier who has some issues with separation anxiety. She's no bother when we're home but when we go out she barks - for context, I'm out most days for around 3 hours, usually in the morning, & maybe one night a week for a maximum of 4 hours. I leave a light on, the radio on a talk station, she has toys to play with and an array of comfy 'safe' places for her to go to. We also have an older dog who is in the same room with her, but she is used to being left and just sleeps when we're out (we have tried leaving them in separate rooms but the younger dog is even worse then).
We don't see our neighbour very often but every time we do (like every couple of months) he mentions the barking again, saying she does it all the time when I'm out & asking when she's going to stop, if we're trying to train her, etc. I've apologised many times and said she's still a puppy/young dog & that I'm trying my best but I can't stay home all the time! I get that it must be annoying for him but it's not at unsociable times and honestly I don't really know what else to do!
Any ideas?!
