Is it normal for a dog to feel lethargic or not act right after getting a heartworm shot like diroban for the first time?

Yesterday afternoon, my dog received their first heartworm injection, and they’ve seemed really lethargic and not quite themselves ever since. I understand every dog can react differently, but I'm worried about whether this is a normal side effect or something I should be more concerned about. How long should I expect these symptoms to last, and at what point should I consult a vet?

Answer

It's understandable to be concerned when your dog shows signs of lethargy following a heartworm injection. While some mild side effects can be normal, it's important to monitor your pet closely to ensure their safety and comfort.

  • Mild lethargy is a common side effect after heartworm injections.
  • Monitor your dog for any additional symptoms or changes in behavior.
  • Consult a veterinarian if symptoms persist or worsen after 48 hours.

After receiving a heartworm injection, it is not unusual for dogs to exhibit signs of fatigue, mild swelling at the injection site, or decreased appetite. These reactions typically subside within a couple of days. However, if your dog shows severe symptoms like vomiting, collapse, or seizures, it is crucial to seek emergency veterinary care immediately. For peace of mind and professional guidance, you can also reach out to a vet if your dog’s condition does not improve within 48 hours.
