Hello, my dog is after anual shots Nobivac L4 and Nobivac DHPPI but few hours after the shot i noticed that she is foaming around her mouth so i wioed it off and from that time I sa no more foam. She has temperature of 38.4 degrees celcius. Now she is sleeping normally. Is this something to worry about? Thank you

Hello. Cunlee may have had a mild reaction to her vaccinations, but her temperature is perfectly normal for a dog. If she is resting comfortably, just monitor her. Most vaccine reactions subside in 24-48 hours. Thanks for using Petco Pet Education Center, formerly Petcoach.
