If you are able to rush her off to the vet, they should be able to give treatment that would reduce the side effects. They o=(or you) could call the Animal Poison Control Center for specifics on toxic dose, drug interaction and treatment. Phone(NNN) NNN-NNNNand there is a fee.
The normal Rimadyl dose is 2 mg/day and it can be divided. A 75 mg tab is the daily dose for a 35-40 pound dog. How much does your girl weigh?
Aleve is quite toxic in dogs and the toxic dose is not much higher than what could be used for treatment. 1-5 mg/pound causes gastric ulcers and more than 5 mg/pound may cause kidney failure. The 220 mg dose of Aleve could cause gastric ulcers and possibly kidney failure in a 35-40 pound dog. The risk is lower if only one dose is given than if it is given repeatedly.
The side effects of Aleve may occur at a lower dose because she is also getting another similar drug.
Treatment for the Aleve would include inducing vomiting if it is done shortly after she ate the pill. If it has been more than an hour, the drug has been absorbed. Activated charcoal for several days can help adsorb drug that is excreted in bile.
Omeprazone (Prilosec) comes as a 20 mg OTC delayed release capsule and can be used to reduce the risk of gastric ulcers. Famotide (Pepsid) is another option.
IV fluids could help protect the kidneys.
Let me know if you have follow up questions.
