I have a greyhound puppy which is about 6 months old. I’ve got him when he was about half a month old. But now with time situation got worst. My puppy bites every member of family whenever we try to pet him. He bites hard and bites our clothes and rip them. I tried to say no and shout but he does not listen and barks and get aggressive at us. he’s like the most aggressive and stubborn dog ever. i want him to stay calm and stop him bitting. Please help.
