Hi, I have Mazzy.. its been a month now... she is settling in nicely... and starting obedience class tommorow... shes still leash reactive.. but class will help with that... I hope... Mazzy is a 2 year old rescue for those that did not read my previous post... she is still kind of mouthy for 2. but what concerned me is Sat and Sun nite... My nephew locked me out of our house on Sat night and left when I went to take her out to go to the bathroom... I used a neighbors phone and called him it took him quite a while to get back.. I went to the main street we live on to look for him... and on my way back into our building Mazzy latched on to my coat... I foolishly pulled and tore a whole in it...nice coat too....:| but the issue that actually scared me was Sunday.. on the way back from our walk Sunday night.. I was going back into the direction of our complex when she suddenly jumped at me and started grabbing at my sleeve .. or arm? this of course starting the clothes ripping again I stood very still and she let go... I then started to move forward again and she launched at me again... this time she grabbed my arm and when I went to pull her my arm out of her mouth she got my skin.. its not too bad.. I think she was trying to get my sleeve again.. but none the less the issue scared me ... trainer thinks she was using it as an attempt to try to stop me from going home... I just bought a new prong collar.. and she freaked out when I was trying to put it on and grabbed my sleeve again today... tore another hole so needless to say she won that one.. as the prong collars are a bear to put on .. she initially did not like the reg chain collar but those are easy to put on and now she accepts it willingly.... also today she heard my sister coming home and tried to stop me from moving forward by jumping and nipping... she tried to grab my ankle this time... sooo..... herding ?? mouthing??? behavior issue or something else.. what to you think? I now never take her out without food ... she is very very food motivated. with this new issue and the dog issues our walks are not fun... I did have her at the park yesterday.... she saw some geese and tried to get them ( she was on leash of course) I used food to get her to focus toward the end of our session I had her completely ignoring the geese .... so all is not lost... but the biting on my arm is a little scary... even if she only meant the jacket.... I'm not so sure as she has grabbed arms in the house in an attempt to play .. when I correct her she stops... but she is more stimulated outside.
