Hi
I have a 7.5 male . He has over the last week turned into a nightmare when out. Indoors or in the garden he is perfect. When out he now he fights over the lead tugging it and growling at me (he is very strong). He jumps at people lunges at other dogs I cannot let him off lead he has lost all sense of recall and doesn't show any interest in any treats I offer I am at the end of my tether and wondered if neutering could be the answer. I do Loads with him never leave him to get bored, provide lots of mental stimulation , do classes and training I am following all what trainer has said but he is having none of it :((
