I took 8 little basset puppies and their momma to the vet Wednesday (2 days ago) for their first shots... momma needed her yearly boosters so we got those as well... less than 24 hours later we had a few puppies vomiting just once or twice... today all have thrown up at least once or twice...and now momma dog... no diarrhea- very active, playful... barking like mad... will eat if I offer them chicken and rice... but not really wanting the dry kibble... drinking, peeing as usal (based on the puddles)... mom still nursing off and on (pups are just turned 7 weeks)- They would dearly love to eat the throw up if I can't move fast enough... I've called the vet twice now who recommends watching- if sx change to bring them back in but the activity level and fluids are good... is it possible this is a reaction to the vaccine? I have 2 other dogs that did not get any shots and are perfectly fine! Has anyone had this happen before? They don't act sick at all!
