this is kind of in relavince to my other thread about my puppy fear barking. i have being trying to get a handle on her socialization. we have been socializing her since 4 months but i am now in socialization over drive and i have been taking her once a day to socialize. well, the past 3 days i have taken her to the local dog park in the morning and she has started barking when i let her off leash into the park. the first day i thought, ok well its because there are people sitting there, which she has never done before because if they weren't bothering her, she ignored them. second day, the same thing and i thought ok welll, she is afriad of the man walking towards her. well today, there was no one around. she barked for a good minute atleast before she spotted the other dogs and people. she began to bark and run 50 yards to where the other dogs and humans were. barking and wagging her tail. when up to the 3 people down there sniffed them and quit barking when she got down there. now, she is a talker. when we go to family that lives close by, and we turn down the dirt road, she knows where we are going and whines. could she just bark because she is excited? she only barked at 2 people today (which she is getting better at) and one of them she knew because she played with his gsd before and had left him pet her etc. so could she just be excited and bark because she doesn't growl or lunge or anything, although she will have her hackles raised but she is very submissive towards other dogs. if a dog chases her she will tuck her tail or if the dog is bigger than her. i also tried the treat thing today and seems to have worked. should i be worried about her becoming agressive? she has never tried to bite anyone or lunge.
