[Mom to Hot Rod]

I had a scare yesterday. While we were out for a walk, a tractor drove by and scared Hot Rod a bit. Right after that it seemed like he was not right. I didn't know if he had gotten scared from the noise or what; he could grasp his breath but he was breathing okay, if that makes any sense. Long story short, after an emergency trip to the vet, she thinks that it was reverse sneezing and that it could have been brought on by allergies. Maggie sounded like this when we first brought her home (she stopped making this sound) and vet couldn't diagnose cause we couldn't explain it but did say that her trachea felt fine.

Anyhow, she suggested children's benedryl for Hot Rod. I'm really not one for medicines all the time. Does anyone else use benedryl for their babies? And if so are there any side effects, example-sleepiness? Thanks for your responses.
