hi,
my yorjie started vomiting and having loose stools, was very not with it. we took her to the vet and they are "watching her". i tried to think what could have made her sick. then it hit me. last week i sprayed the cobblestone courtyard in front of ourr house with weed killer. even though it is not an area that she frequents, she does walk on it to get back into the house,always leashed. i wonder if this could have been the culprit?
could this have been my fault and will she be effected adversely from this. the vet said it could have been anything.
thanks
