I've recently gone from a one dog household to a three dog household with the introduction of my first two little foster dogs. Things have gone fairly smoothly but my own dog Kayla (lab x bc) has become very vocal! When the two little fosters play together Kayla starts with the barking - unfortunately it's a loud ear-splitting barking. It's not an excited bark (which is higher pitched) so I think it's either attention seeking barking or related to herding behaviour.
So my question is how can I reduce this type of barking? I reward quiet behaviour, and try to distract her when she starts to bark - I've tried different words like 'enough', 'ah ah', loud noises etc but it doesn't seem to be helping - she just starts up again. Once the two little dogs settle down she is fine, no barking. Help...my ears are hurting!!!
