Shady my 3yr old Rottie x GSD is fear aggresive to dogs she doesn't know, but once she realises a dog is not interested in her and will leave her alone she is fine with them. She doesn't play with them but ignores them or has a quick sniff before resuming chasing her frisbee.
I thought she was really improving as 2 labs she met about 8 months ago and was fine with but hasn't seen since come bounding out of the woods the other day and she went and sniffed them and then was quite happy when they bounced around and sniffed her a bit. She seemed to remember them so just got on with her game.
G. Retrievers she has always seemed to get on well with and makes friends easily with them having a few good friends in them now so when another with a man I know well came to the field today, I done the usual and just popped her on lead till he had got to me. He knows Shady so kept his on lead even though it takes no notice of other dogs (just Shadys type) Shady never reacted and was quite relaxed as we spoke, so I asked him if I was ok to let her off while he kept his onlead so she could realise his dog was fine and wouldn't bug or chase her and then they could be friends. (Thats the way I have found Shady accepts dogs and makes friends)
He said yes, so I let her off and was very relaxed as I was certain there would be no problem, she chased off after her frisbee ignoring the GR and bought it back. Then suddenly dropped it, went and sniffed and then dived on the GR having a go at it, the GR retaliated. It was over in a few seconds as, as soon as I stepped forward and told Shady to back off and got hold of her she came and stood quietly by me. I had to pop her back on lead as I could feel she would have gone in again.
Once on lead she stood perfectly calmly beside me on a slack lead while I aplogised although the man was fine and said hopefully one day they would get on.
Why did she take such a violent dislike to the poor GR?. I really can't understand her. If it had glared at her which she hates or been trying to leap on her then I wouldn't have been surprised. It shocked me as a quiet dog like this and introducing this way has never failed before.
Its left me feeling I don't think I can really trust her to introduce her to anymore dogs and just in future let her mix in her little circle of friends she already has and leave it at that.

Was the GR a bitch, if so this could just be a case of bitch hate, it happens usually in the home but sometimes in an area the bitches believe to be part of their territory.

Hi Bev

some bitches simply don't like other bitches - particularly if of similar age.  It doesn't mean they will never get on but I think perhaps some give off signals which we miss but other dogs dont and I've known some which like to start off intros with being a bit 'dominant' so that they establish their own pecking order before relaxing or going on to play.  Not ideal but it can happen and it's a question of guaging whether this is your girl's attitude or not.  There may have been subtle signs in body language which only the two dogs picked up on, especially as one was confined to the lead.

Personally I would not intentionally encourage a meeting between dogs where one is free and the other is restrained as it's not on an equal footing IMO.  Better that both dogs be on or off lead at the same time to allow each to move within it's own comfort zone or well away if  preferred.
