My little girl Chloe got a spider bit about a week and a half ago. We knew it was a spider bite because that is what the vet said. She has been getting better slowly but it is very itchy and painful. We where told to give her benadryl which we have been. Today after she took it she became very agitated. This is very unusual for her because she is always happy never snippy or agitated. I am just wondering if anyone knows or has experience with this?
