I have three Toy Yorkshire Terriers two brothers who are two years old and one who is three years old. The problem I have is that the eldest of the three has started to attack the two younger ones. This only happens at bed time and has only just started in the past 2 / 3 weeks. I understand that there always is a leader and I can see that the eldest is the leader of the pack, but it is getting to the stage where the younger two will not get into the same bed as the oldest and they are cowering in the corner of the room because the eldest gets out of bed to get them. They have been sleeping together for 18 months with no problem and now all of a sudden this. The two younger have been neutered but the oldest not.
Can anyone help??
