Here’s an exhaustive discussion of barking issues from ASPCA

I highly recommend you get a citronella collar for this attention seeking barking your doodle is engaged in. I used one in the past for a couple of dogs I had who barked excessively, the collars work great. A reasonably smart dogs learns very quickly to just not bark when the collar is on - so don’t make the dog wear it all the time, that’s cruel because dogs need to communicate and let off steam sometimes. But for the overnight while sleeping and during that bedtime routine it’s okay, so long as you accept that your dog might not alert you to an intruder.
Citronella collars don’t hurt the dog at all, it’s just a smell they find unpleasant and as I stated, a smart dog will only get sprayed once or twice before making the connection and going silent mode with the collar on. MAKE SURE THE COLLAR IS ALWAYS LOADED WITH SPRAY AND FRESH BATTERIES, or the dog will lose bark inhibition while wearing it.
Good luck. Please have patience for your puppy and don’t hate it for doing what dogs do anymore than you’d hate your children for doing what children do.
