Hi there,
I am little worried now, my Goofy (labrador) is turning 4 this year. I have seen some changes in him recently. He gets more aggressive now. I don’t know the reason yet. He sometimes get angry with me and doesn’t listen to my words. Last day, when my friend came to my home, she was petting my dog, initially he didn’t respond but she tried to take him and keep in her lap, he suddenly bit her. She really got hurt. I apologised to her but she didn’t take it as a serious matter. But I am afraid about him now. If he bites someoneless they might go for a case and I read that http://www.monteithbaker.com/practice-areas/personal-injury/dog-attacks/ and I can’t do anything since it is his behaviour. What might be happening to him? How can I control and discipline him?
