Hi can anyone help my choc lab of 5 years as now decided to started barking anywhere between 4.30 and 5 in the am. she is not on her own and is fit and has plenty of toys etc. I can only think she hears the delivery man with the bread and milk being delivered to my corner shop two doors away. The problem is my neighbours are now complaning. I have explained the situation and i wake up as soon as she barks then i feed my dogs and exercise them. At my wits end any ideas someone suggested a barking collar but i have never used one and am unsure please please can anyone help me. i live in a detached house. Any ideas much appreciated.
