Why is my dog whining after an opioid pain shot? Should I worry?

As long as he is improving and signs are diminishing, continue to treat as directed by your veterinarian. If he stops improving, worsens or seems more painful then have him rechecked by your veterinarian. Elevate the water and food bowls. Restrict activity as much as possible and leash walk using a harness to alleviate cervical stress.

No, I would not expect her to be in more pain after an injection for pain. Call the vet who saw her today and give him/her an update. If she didn't have an xray of her leg than she probably should. She may also need additional pain medications if the injection did not help.

Since she is taking carprofen she should not be in severe pain. She is probably upset because she has to wear the cone. I am afraid you have to bear it out as she will try to "whine you into submission" ie hopes you will take the cone away. The whining should stop within two or three days. If she keeps whining for longer and you think something is wrong with her or if she gets pale mucous membranes, cannot urinate or stops eating you should take her back to the vet for a recheck,

Some puppies can have some mild pain from the injections. You could call your vet and see if he/she could prescribe an anti-inflammatory to help with the discomfort. It usually only lasts for 24-48 hours.

I recommend a phone call to your veterinarian to ask about additional pain medications. Some dogs are more sensitive than others. My own puppy needed a second prescription medication to make him more comfortable. Although most dogs do fine with just carprofen, it might not be enough for Bella. It doesn't mean anything is wrong, or concerning, but we don't want her to be painful.

This could be a side effect of the morphine administered for sedation. Keep her in a quiet, warm, dimly lit room. Restrict activity as much as possible, especially avoiding stairs or climbing onto furniture. Effects can last 4 to 6 hours, not all dogs metabolize the drug at the same rate so this period could be longer or shorter. If she is the same or worse after the 4-6 hour period has passed, consider having her rechecked by your vet. Contact your veterinarian anyway and discuss options for pain management once the morphine wears off.

If she is whining then she is in pain even if you can’t see any external injury. Internal injuries or illness can manifest in many ways and because our dogs cannot talk to us all they can do whine or cry. I recommend you have your dog examined by your veterinarian as soon as possible.
