Hi and Welcome to JustAnswer!
My name is*****'m a licensed veterinarian and I'd like to be of help to you and Penny Lane tonight.
Sounds like Penny Lane is having an allergic reaction to something like a bug bite or sting. If she is breathing OK, and if her gum color is pink with good color return (in two seconds or less after you push on them), then she should be safe for you to give her Benadryl orally at home at watch her.
The dose for Benadryl is 1-2mg/pound every 8 hours. A dog's dose is much higher than ours.
How much does Penny Lane weigh?
Vomiting is a sign of a more significant allergic reaction. Please check her gum color. . .she may have also a severe drop in blood pressure (hypovolemia) that can affect all of her organs. Are her gums pink or are they white?
She should have 70 to 140 mg of Benadryl, but she may also need an injection of cortisone and IV fluids to make it through this allergic reaction.
Oh good. Sounds like you and she have avoided a trip to the emergency vet.
Make sure to give her enough of the Benadryl, and she should have this dose every 8 hours for 3 days to cover her until all of the allergen should be eliminated from her body.
Glad to hear the good outcome. Remember that Benadryl also has a sedating effect, so Penny will be sleeping well! Don't forget to continue her dose every 8 hours for 3 days, or she may have hives and discomfort again.
Have a peaceful evening!
