I had a foster dog who had a reaction to it. It is not generally severe and the benedryl did the trick for him (a really light dosage of it though, too much will make them sick). His nose was swollen and he was a little lazy for a day or so, but then he was back to the hyper pup I knew! :) I hope Laredo feels better soon!
He's your friend,your partner,your defender,your dog.You're his life,his love,his leader. He will be faithful and true to the last beat of his heart.You owe it to him to be worthy of such devotion
