Hello everyone,I have just joined the forum in the hope that someone can give me advice with a problem my border collie has with nipping any dog that goes near her.She is 4yrs old and we have had her since she was 9wks old.She has always been very nervous of things but she loves people and is a joy with children.I used to take her to puppy training when we first got her to socialize with other dogs but she just wanted to get away from them and was more interested in making friends with their owners,she would nip the pups if they went up to her so in the finish I stopped taking her rather than muzzle her,maybe that's what I did wrong,anyway when we take her out on the beach she wont go near other dogs but if they come up to her she will show her teeth and if they don't go away she nips them.If we meet someone we know and she,s seen the dog before she,s not to bad and just wants to get to its owner for a fuss making of her.Everyone that knows her loves her as she is so friendly with people.I am worried that when she nips one day a dog will retaliate and she will get badly hurt,also not all dog owners will say don't worry about it as I always tell them she might nip if their dog runs up to her.She is scared of them and that's why she does it.hope someone can advise me as its making me a nervous wreck.
