.....this happened to me at my mother's. Tara was up on the bed saying hello to my mum, and my mum's bed is on stilts, so it is high, and because I didn't get to my mum in time, who had lifted her up without thinking, Tara just came flying over the end of the bed when she saw me come into the room. ......luckily it was daytime, and even though I had just arrived, i left straight away to go the 25 miles to the vet. Tara screeched and was limping too, but by the time I got to the vet and she was examined, she was fine....just a wee shock, thankheavens !
....so just to let you know, that if a 4lbs dog can survive that huge drop onto a lino floor, then yours might be ok yet !
....just keep her quiet, and get her checked immediately !
.....so as not to worry too much in the meantime, can you phone your emergency vet and ask for his advice ?
.....it might help you to help her
....i will pray for a good outcome....and don't blame yourself, these things happen - and usually only ever the once, as my mum has never taken Tara onto the bed again unless I am there to watch her !
....i am thinking of you and your baby, best wishes,
