Agressive 17 week old female Labradoodle
Lately, every time I take my puppy for a walk at some point she will try to grab the leash, jumping to get closer to my hand and then when I say no, she gets more agressive and starts to jump and nip at my back, legs, butt. I have tried ignoring her, saying no firmly, asking her to sit, pushing her to the ground and holding her down till she calms down. Today I said Tssst! and initially she was suruprised but then continued to nip at me. I am to the point that I don't even want to take her out anymore. Otherwise she is a good dog, smart, learning commands, I don't know what to do. Can you help me?
