Yes, you can use plain petroleum jelly on a dog in small amounts , but it’s not the best choice because dogs usually lick it off, which can cause vomiting or diarrhea. It’s also better to avoid using it on deep, red, infected, or recurring skin problems and to ask a vet for the right treatment.

Quick scoop

  • Okay in a pinch: tiny amounts on a dry nose , cracked paw pads , or very minor dry spots.
  • Main risk: licking and swallowing it, which can upset your dog’s stomach.
  • Avoid medicated versions: only use 100% plain petroleum jelly if a vet says it’s appropriate.

Safer options

  • Dog paw balm made for pets.
  • Veterinary-approved skin creams for dryness or irritation.
  • Vet care first if the area is painful, swollen, oozing, or not improving.

When to call a vet

  • Your dog keeps licking the area.
  • The skin looks infected or very irritated.
  • The problem is on the face, around the eyes, or on a wound.
