hi sorry to hear about your problem with your little furrbie, i would take her to your vet too. it probably nothing & could just be a side affect. at the very least contact the vet by phone, my vet is really good, they may just adice you over the phone as we all know vet bills can be really high ( although i know we yorkie owners would sell our homes if we had too ! )let me know how you get on. best of luck. luv pauline & girls xx
