Customer thank you so much for your question--can you tell me how much your dog weighs?

Thank you so much for your response!

I was figuring your dog might be close to 50 pounds.
Lithium is actually used in dogs occasionally to treat aplastic anemia, low white blood cells and even aggression, from what I researched.
The dose in dogs in about 10 mg/kg every 12 hours (your dog is about 21.3 kg, so a typical dose for his size would be about 213 mg. So eating 300 mg is not far off of a typical dose, and I found that very dangerous or possibly lethal doses would be more like 500 mg/kg, or about 10,500 mg for your dog!! So there appears to be a wide range for safety.
So this is great news for your dog, and this one time dose should be nothing to worry about. I hope this is a relief. I would not expect any ill effects.
Thank you for your question tonight!
