Long story short. A little while ago outside Sainsburys my friend was waiting with my 1 year old (in pushchair) outside the Sainsburys while I was finishing up in the queue. When I met up with her outside I noticed a very angry looking (snarling) medium sized dog who was flailing with owner (quite a big muscular guy so not sure why he was having any trouble) struggling to control this dog with his leash tied to a pole. I knew he would break loose and when he did I leapt to push the stroller away from his path, unfortunately colliding my friend's foot in the process (not very hard, although apologised profusely as I felt silly). The dog went off and did not land up where my child was. I think my friend thought I was being paranoid. I think it was motherly instinct kicking in as this dog looked pretty agressive to me and was straining on the lead towards us. Was I being paranoid or is there such a thing as motherly instinct? If so, have you experienced it?
