Agressive 10 week old male cream Labradoodle
My 10 week old Labradoodle puppy is a biting machine. He is either a sweet, calm angel or an aggressive demon. He will growl and bite and me so hard that it leaves a mark or breaks the skin. He will bite the heck out of my ankles or jump up and bite at my pants all day long. I try to tell him 'no' but he just gets more and more aggressive. I'm not sure what to do. I love this puppy, but when he acts like this, I get very frustrated/angry. He also bit my 7 year old neighbor the other day and made him bleed. Needless to say, his parents weren't very happy, but I didn't know what to do! I have a million toys, bully sticks, antlers, etc. for him to chew on, but for some reason, he wants skin more. What is the best method to get him to stop being so aggressive with people?
Also, this is a side note, but he does not like walking. I try to take him on walks throughout the day, but he just aggressively pulls away toward the door of my apartment. It's like he doesn't like to be outside or on a walk, just simply wants to do his thing and get back inside. This is frustrating for me because I want him to go on walks so that he can unleash some of his energy through exercise rather than aggressively attacking me when we get back inside.
Any and all help is appreciated!
Thank you :)
