Why it is dangerous
Old-style naphthalene mothballs are the most toxic; newer types of mothballs are less toxic but can still cause illness. Dogs are more prone to swallowing them, while cats are more sensitive to their effects. The chemical can also be absorbed by inhalation or through the skin.
Possible signs
- Vomiting
- Naphthalene smell on the breath
- Pale or brownish gums
- Lethargy
- Difficulty breathing
- Tremors or seizures
What to do
Remove any remaining mothballs and keep the packaging. Call your veterinarian immediately. Do not try to induce vomiting unless the veterinarian tells you to.
Do not try to make your pet vomit; if needed, the vet will do it at the clinic. Bring the packaging with you.
