I am so sorry to hear about Mishka. My name is Rebecca. I am a veterinarian and will do my best to help.

Unfortunately morphine is not well absorbed by mouth in most dogs, so it is sometimes not great for pain. Is this oxycontin you have, or morphine?

Expert:  Rebecca replied 12 months ago.

The doses are different. Oxycontin would be more effective and the dose is .1 to .3 mg per kg of body weight, so 4.5 to 13.5 mg. Morphine dose is .5 to 2 mg per kg, or 22 to 90 mg. These doses are repeated as needed once to 3 times daily.

The morphine may not be great for pain, but can cause vomiting, and restlessness. The Oxycontin might be better for cancer pain than morphine so I hope that is what you have.

I hope this helps her, and you.
