We're heading out for our summer road trip next week, so we took Spring and Remi to the vet today for their annual check-ups and vaccinations. They both had great exams and a clean bill of health. As soon as we got home, Spring started wheezing. She was having a hard time catching her breath. We immediately recognized it as an allergic reaction to one of the medications. We administered Benadryl right away and rushed her back to the vet. By the time we got there, the Benadryl had already started to kick in and she was doing better. The doc gave her additional benadryl and a steroid and she is doing just fine now.
All dog owners might consider keeping Benedryl on hand in case their pups have an allergic reaction. It can save their life. Most Benadryl tablets are 25mg. The proper dosage is 1mg per pound of body weight. Of course, it can be used on humans too if they have an allergic reaction.
Now, Spring will need to sleep off her Benadryl induced nap...
