hi i have a 10 year old non-neutered male german shephard and his whole life hes been very aggressive, barking at everyone that passes by the house, even little kids. but the biggest problem i cant figure how to solve is him getting in fights with other dogs, if he incounters a female than usually ok mayb hell try to get frisky with her, but if its a male almost 100 percent he will jump on the dog and start a fight, ill yell at him NO, bad dog...but doesnt seem to work. Just the other day this very small cute dog just minding his buisness than my dog comes grabs it in its mouth and holds in the air for a few seconds before i could manage to yank my dog away, something out a horror movie and i could see the terror in his owner, so i said enough time to get help so please ne advice much appriciated. Want him to b more calm at peace and always wanted to b able to take him to one of those off leash dog parks
thanks
thanks
