My dog suddenly has hives, how long do they usually last?

This evening, I noticed my dog suddenly developed hives on his back after we got home from our walk. It’s really unsettling to see him uncomfortable, and I'm not sure what might have caused this reaction. How long do hives usually last in dogs, and is there anything I can do to help him feel better?

Answer

If your dog has suddenly developed hives, it's likely an allergic reaction, possibly to something he came in contact with during your walk. While hives often resolve on their own within 24 hours, there are steps you can take to ease your dog's discomfort.

  • Keep your dog calm and comfortable to avoid worsening the reaction.
  • Bathe your dog with cool water to help soothe the skin.
  • Consider contacting a vet for guidance on appropriate antihistamine use, if needed.

Understanding the cause of hives is important because, while often harmless, they can indicate allergies that may escalate if not addressed. Allergic reactions can vary from mild to severe, so monitoring your dog and seeking veterinary advice are crucial steps in ensuring their safety and comfort.
