Everything I read about Vizsla's prior to getting one went on and on about how clingy they are. I have a 4 month old puppy and she is really smart but pretty independent too. When I take her to the dog park, she runs off making new friends and forgets I am alive. When we are in training-mode, she is extremely attentive but when at the dog park or in the backyard, she almost acts like she cannot hear at all. Is this a puppy/attention span thing or did I just get an independent dog?
