My 20 month old male labrador is not neutered. For the past month or so he has started displaying bullying behaviour towards younger male and female dogs. He will run around the dogs barking and making growly noises and if is difficult for me to get him to listen to me. I eventually manage to grab him after following him around in circles. This is when he is off lead and if on lead will bark and stand his ground as they pass by. Tonight he did this again off lead but was aggressive towards a young retriever which was very distressing for the dog, owners and myself. We attend an obedience class and up until now his recall has been really good. I was not planning fo get him neutered but would consider it if this behaviour continues. Any advice would be greatly appreciated as otherwise he is a lovely dog with a cheeky personality.
