Why is my dog whining and not eating after Dilaudid from the vet?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Female | spayed | 4 years and 6 months old | 48 lbs

I just brought my dog home from vet for unknown pain in her her right leg. The vet gave her dilauded to sedate her so she could be x-rayed. That was about 5 hours ago and she is still whining and won't eat. I also can not give her any of her medicine because she refuses to eat or drink anything. Is this normal for dogs coming off of dilauded and will she get her appetite back soon?

Unfortunately some dogs do seem to be disoriented from hydromorphone and similar medications. Usually dilaudid only lasts for about 6 hours, but there can be individual variation. If it does not specify that the medication needs to be given with food you could place in as far back in her mouth as you can and then hold her mouth shut until she swallows. I would expect her appetite to be normal tomorrow morning but wouldn't worry too much if she skips a meal tonight as long as she doesn't have any other health problems.
