ya know as i was reading this it made me think of something my abbey did here a while back... she has NEVER shown any signs of aggression to anyone, she can get a little mean to one of the other dogs if they try to take her toy, but as far as people go never... UNTIL.. the grandkids came over.. i always put the dogs up when they are here but they happened to stop one day unannounced and the dogs were out.. i put them all up (4) except for abbey because she was somewhere in the house and i figured since she was the smallest that she would be fine. but as i was paying attention to the grand kids she lunged towards the youngest one, hes only 2, and at first i thought it was one of the little yorkie dogs we have that was standing behind our grandson so i corrected her and though i should put her up anyway.. then a week or so later they came over while dog were outside playing and we all went out and i seen her do it again.. luckly she stops before she makes any contact, like its just a warning that your getting to close to me or something.. i was really shocked at her behavior and when i said NO to her she immediately lowered her head and acted like she was sorry, or sorry she got caught,.. but i can not understand why she does this.. it was to she same little boy, the 2 year old.. he is in terrible two stage, but that's a whole different story and website.. lol.. i thought maybe he has hit her or something, because his parents let it happen at their house, again, another story, but we do not let it happen at our house and we will correct them when we see any sign of it... i think kids need taught how to behave around animals just the same as adults.. maybe i am old fashion because some people don't agree with me.. anywho... sorry about the rattling on but i'm thinking maybe my abbey didn't like not having the attention with her.. hope you can figure out what it may be soon.. love these furbabies just like our children..
