Hello, thanks for your question. Some dogs may experience muscle pain with the tail and hip muscles for rigorous activity or very long walks. This is commonly called swimmers tail. You can give buffered or enteric coated aspirin at mg/kg every 12 hours
Sorry the dose is 10mg/kg
Is that the same aspirin you would give to humans? how is it best to give this?
Yes the same. You may put it into something like a piece of cheese or peanut butter and have her eat it
She appears to have settled down a bit now. Do u think this is serious enough (or could be serious enough) to call the emergency vet tonight? Or would you recommend taking her to see a vet in the morning and leaving her tonight?
If she continues to be restless and cannot sleep then see emergency. But if she can get comfortable but in the next day or so she seems sore in her tail or hind legs then see your regular vet
