Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Welcome and thanks for asking your question. My name is***** am a licensed veterinarian. I am not set up to make a live call. But, I am happy to answer your question on this thread. First I need to ask you a few questions so that I can be well informed and give you the best advice.
1- How much does she weigh?
2- How long has it been since she ate the rimadyl?
3- Do you have hydrogen peroxide 3%?
Friend, I am sorry for the delay in response. But, I was offline by the time you came back. When you post a question you will work directly with an expert live on real time. If you leave then the expert may not be there upon your return, at that point your option are to post the question to another expert, opt the expert out or wait until the expert comes back. I am sorry again but I didn't know if you were coming back so I left for the night.
In response to your question, the therapeutic dose for rimadyl in dogs is between 1-2mg/lb every 12 hours. The toxic dose for single acute overdoses of 20mg/kg or above we tend to see gastrointestinal ulceration. Doses above 40-50mg/kg we see renal failure. In this case your dog took a dose of 20mg/kg so she is within range for gastrointestinal ulceration, abdominal pain, vomiting, etc. I would recommend you start her on Pepcid AC (famotidine) 20mg every 12 hours for the next 7-10 days. If you develops symptoms like: Anorexia, vomiting, abdominal pain, etc. have her checked immediately by family veterinarian. Do Not give things like Pepto Bismol.
