hello i wondered if anyone could help me .
I have a 20 month old red border collie and over the last few months she has been behaving strange . When we got her at 7 weeks she was afraid of bin bags when you shake them . But now when i get washing out washer she hides and she frightened of the clothes horse also and when we shake clothes when they come out washer she hides. But tonight she was at my siisters house and my sister ordered a pizza when it came and my sister brought it in the house she seen the box and was frightened and went and hid . Does anyone know why she might be doing this she was ok with washing and boxes before
