Dogs

[Kelis]

I have a 12mth old golden retriever and everytime I take him to the park or the beach some other dog will always go to attack him.
Is it my dogs fault?
He is always on a lead, he isn't desexed, they come up to him and sniff and then he gets a little excited(gets into play mode) then the other dog suddenly turns aggressive. Its not all dogs but out of the 10 dogs he sees always 1 will go to attack. And the owners of the other dogs are very shocked saying their dogs don't normally act like that. So it makes me think that it is something my dog is doing. Also every dog that has attacked has not been on a lead.

So many factors here, but yes, you've pointed out the likely factors:-

Dog not desexed.
Dog onlead, not in a position to manage itself easily with other dogs offlead.
Dog giving off excited body language mistaken for aggression.

Tell me - why have you not desexed your dog? Do you itnend to breed it? If not, there is really no reason not to desex your dog and plenty of reason to. No unwanted pregnancies, less aggression, few health problems. In your case, a male undesexed dog is always going to be a bigger target than a desexed male dog to other undesexed male dogs who will see your dog as a potential challenger.

Onlead vs offlead, likely your dog though appearing to want to play, is also nervous at the constriction when the offlead dog approaches, and over reacts when they sniff him?

I'd be seriously considering desexing him, doing some obedience work with him and then taking him to some offlead exercise areas where you can exercise him offlead and get him used to sociliasing with other dogs? Do you have friend with dogs whose dogs get along with yours? I
