Zorro's coming up for 3yrs old and was neutered at 6 months. He's always been really good around other dogs, usually just ignoring them, saying a polite hello or occasionally (if it's a leggy working cocker or a whippet
) having a game. He spends 99% of his time on walks either following scents or chasing a ball.
Recently he's started developing a real dislike for entire males. It started a few months ago with one dog in our park who Zorro really just cannot stand (this dog has never touched him at all but Zorro will go up and shout at him given the chance, so we have to avoid him). Then the other week one of my dogwalkers said that there's a dog called Leo who they walk, entire male, alsation/staffie/lab cross (AKA Heinz 57
) and that Zorro really doesn't like him. Leo's actually quite overbearing for alot of dogs but takes notice of Zorro, but they're now walking them separately to avoid uneccessary conflicts.
The other evening an entire male was bounding around and came over to Zorro and he told it to bog off in no uncertain terms. Then this morning the same thing again with another entire male. So it looks like quite a pattern - with bitches he is fine and I've never seen him snap at a neutered male either.
He doesn't tend to approach other dogs himself so it's really only if they come to him.
I'm loathe to start keeping him on the lead as he has so much energy, and also it won't solve the problem as it's not him going up to entire males, it's them coming up to him.
Has anyone else come across this kind of thing before?
