chloe & patch got boosters today. chloe got sick right after we got home; she vomitted numerous times so i toiok her back to the vet. he gave her a shot of atropine & said her gums were pink and said it was probably nerves - give only liquids, etc. she vomitted once or 2x after she came home and hid until 45 min ago. she came out for a bit then threw up 2 more times. however, she doesnt have nything left to vomit up. its just dry heaves. he said something about benadryl (12.5 mg) but is this ok since shes throwing up? has anyone experienced this?
