hi, we have two small children 2.8 and 6 months, since the second one was born (and whilst i was preggers) the dog (bitch, rescue dog approx 6 years old had her for two years) behaviour has worsened in terms of pulling on lead, barking aggressively at other dogs when on lead . she gets 2 good walks a day, and off the lead is ok most of the time, but if we are out with the kids she gets quite barky with other dogs and runs up to people who come nearby. has anyone had experience of this please? starting to do my head in as its hard enough taking all three out without dog being badly behaved!!
