I've had my dog for about 18 months, he's around 8 years old and a border collie cross. I knew his previous owner who had him for about 4 years but he was an outside dog who didnt get much attention. My problem is i have a 1 year old niece and the other day he went to bite her as she was walking past him. Her mum is already nervous around dogs and this has just made the situation worse. At the moment our dog isn't used to being around young children so i would appreciate any tips on how to work on this problem bearing in mind my niece probably wont be visiting for a very long time! Any help much appreciated. Thanks. x
