I have a Westie, male, 8 year old. We have been in this new house for almost a year. He has been quite good playing at the back garden just keep barking at the squirrels that he sees in the trees. But now the next door neighbour has a kitten and my dog can smell it through the fence. He is going mad. Starts with wee noises and then he can't stop barking. I don't know what to do. My neighbour from the other side already complained. Please, please....what can I do to stop the barking? Need advice urgently.Thanks
