Heya can anyone help? I have a 12 month old german shepherd dog and I'm looking for socialising and training classes. She is well behaved generally and usually obedient but she barks at people I welcome into my home (not aggressively) and she barks/lunges at other dogs on the lead. She appears to be nervous when dogs approach her and some times she's fine and tail wagging and others she's not. I've heard about classes but am unable to find information times, place and cost! Thanks in advance!
