I have realised that at least two out of my three FBTs are male due to their barking. This isn't a problem except that they like to do it until 3am! I was reading on the internet a bit and saw that perhaps turning the lights on earlier in the day and turning them off earlier at night could make them calm down on the barking a bit later in the day. Would this work? Are there any other methods that might help with this?
Thanks!
