Hi, I'm Dr. Peter. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Welcome! Thanks for asking your question. My name is***** will do my best to help you today. First I need to ask you a few questions so that I can be well informed and give you the best advice.
1- How many milligrams or grams was in the sachet?
It could not be a total of 4.5mg, the dose for panacur starts at 50mg/kg.
Was the panacur for her and you were to divide it to be given in 3 days, correct?
Friend, panacur is a very safe medication; dogs can tolerate up to 100 times the recommended dose. She might develop vomiting or diarrhea otherwise very likely she is going to be okay. I would keep an eye on her for the next 24 hours, if she develops vomiting or diarrhea this is what you can do:
1- Do not give things like Pepto Bismol or Imodium.
2- No food or water for 4-6 hours. Need to give her gastrointestinal tract time to rest.
3- After 4-6 hours offer a small amount of water. If no vomiting after 1/2 hour offer a bland diet of rice with boiled boneless chicken or ground beef.
4- If she continues to vomit after doing the above she will need to be seen by your family veterinarian for a hands on examination.
My goal is to provide you with excellent service - I hope I've provided the information you were seeking, if you feel you have received anything less, please reply back as I am happy to address follow-up questions. Kindly rate me when you are done.
1- Did you get the panacur from your vet?
