Hi, can anyone offer some advice please?? I have 2 dogs, H who is 20 month old Doberman had since 8 weeks no problems. Poppy rescue 11 months old fostered all her life in a house with many other dogs adopted by me 1 month ago. pretty good with other dogs off the lead a bit yappy but not nasty, comes back when called but the problem is on the lead, when she sees another dog she goes absolutely bonkers barking and lunging pulling my arm off. H has now taken to copying her which is causing us a major problem. i cant walk past i have to wait trying to hold both of them till the other dogs passes. any ideas???
