When I see a man approaching us, I make Titan sit and look at me. I tell him it's ok and to look at me. This works 95% of the time.
When he continues to watch the person or continues to want to get the person, I know that something could be wrong with the person. I then move Titan away and we both leave the area as Titan and I continue to watch him.
I only use his muzzle when we go on play dates to meet a new dog or go to the vet.
He usually lunges at any man if they are within 10 feet of us, especially if they talk to me or Titan or stare at Titan. I will ask the person to please ignore us and Titan will calm down after we move away from the person.
They both are terrified of Titan because of his size. Could he be sensing their fear that is causing him to lunge at them?
Muzzle, why do you put a muzzle on this dog for other dogs and vet?
Why do you try to move the dog away? Why not ask the man to move so you can keep control?
Yes, the men could be nervous but hun with all you have explained so are you. When you throw off your nerves it will also put the dog into a state of fear aggression and now the problems come.
If Titan was a rescue, and he doesnt like men then he most likely was abused by a man in the past. We had a Great Dane when I was young. My parents adopted him from a young lady who's boyfriend was abusive to him. It took a VERY long time for him to move forward enough just to trust my dad. (Dad and Dane was living together 24/7) It was so bad that even with just a little "horseplay" all my mom had to do was let out a little scream/yipe and Blackjack would breakdown the door leading into the house from our entryway, grab my dad by the foot, and drag him off the couch. He had his issues with men (all men in general) but was an awsome dog.
Xtrain I am only quoting you but what you posted is not always correct. Not coming after you just gonna use your post to explain.
Abuse to an animal doesnt always come to hate b/c it is a different sex. I will give one example: I rescued a Great Pyrenees who was beaten by a black man, he was tied to a tree and beaten, when I got him he had to go into surgery b/c his collar (2" thick nylon) was embedded in his neck. He never went after a black man, he did though go after dogs as he was dog aggressive (not there temperament at all) so not sure if he had this before or after I received him.
Now dogs can choose a human sex they like better then the other. I have seen many dogs be this way.
We had a lady who rescued Great Danes (not going after the breed) she has one that had to be brought into the hospital put in the door and hold it there so the vet could tranquilize him, he completely hated men. Was never beaten, or abused in any way. The owner had to put it into rescue b/c she was very ill. Long story!
Anyway just making a understanding point.
Deb Ii need some of the questions answered so I an answer for you like you asked me too. I want to help you get this problem under control
