He gave her a shot of it this morning so I'm not sure how long the shot would last in her bloodstream. IOW I don't want to overdose her. At 10 pounds not much room for error. BTW I tried that last year on her with this and it didn't work. She shows vaccine reaction symptoms but the issue the doctors have is it waiting a week to happen. We do live in the woods and yea I thought about Poison Ivy etc. Vet last years said it was unlikely because of a Ratty's coarse fur.
He wouldn’t have given her any more than about 1 mg per pound. Injections don’t metabolize any slower than oral, they just work quicker. It should be okay to give him some moer.
The wife is a pharmacist and wants to know if the dog appears to have any respiratory distress.
You should be able to dose her with baby Benadryl. Follow the instructions for a 10 pound baby.
