Hi there! I’m sorry this wasn’t seen until now – I check the site every day, but sometimes days-old posts just don’t show up right away!
In the future, I would NOT administer anything without your vet’s input. Some human medications might be okay but it’s safer to involve your vet in that question, as they know your dog and her medication tolerance. A better option would be crate rest until the vet appointment (with potty breaks on leash to ensure she doesn’t go running off like a goofball, further exacerbating the injury).
How is she doing today?
Please, please get him seen by a vet.
