How licking differs from swallowing—but still risks poisoning
Your dog’s tongue absorbs toxins rapidly, especially with naphthalene, which dissolves in saliva. Even a brief lick transfers enough chemicals to irritate the mouth and stomach lining, often causing excessive drooling within 30 minutes. The real danger is systemic absorption—these compounds bypass the digestive tract and head straight for the bloodstream.
Watch for pawing at the mouth or smacking lips, signs of oral discomfort. Rinse your dog’s mouth gently with water if they’ll tolerate it, but don’t force it if they’re agitated. Skip food or treats until the vet approves—eating can push residual toxins deeper into the system.
Why a 15 kg dog isn’t ‘safe’ from small exposures
While larger dogs handle some toxins better, mothball chemicals disrupt red blood cells at any dose. Your dog’s weight might delay symptoms compared to a puppy, but it doesn’t prevent organ damage. The liver works overtime to break down these compounds, and the process itself generates harmful byproducts.
Breathing matters too—mothballs release fumes that affect the lungs. If your dog was near the mothball for more than a few seconds, mention this to the vet. Respiratory irritation can develop into coughing or labored breathing hours later, requiring oxygen support.
The critical 8-hour window after exposure
Most vet visits for mothball exposure happen in two waves: immediately after ingestion, or a day later when secondary symptoms appear. Don’t assume you’re in the clear if your dog seems normal post-lick—blood cell destruction is a silent process. Insist on a complete blood count (CBC) even if the vet initially suggests monitoring at home.
Ask about baseline liver values today versus retesting in 48 hours. Some vets recommend subcutaneous fluids to help flush toxins if your dog can’t stay for IV treatment. Bring a fresh stool sample to the follow-up—discolored feces (pale or blue-tinged) indicate red blood cell breakdown.
When to bypass the clinic phone tree
If the clinic puts you on hold or offers a callback, state clearly that it’s a "mothball exposure"—this should trigger faster triage. Describe any existing conditions like heart murmurs or allergies that might complicate treatment. Vets prioritize cases where early intervention prevents costly ICU stays later.
Pack a travel crate with familiar bedding—stress from the car ride can mask symptoms like tremors or confusion. Note the time of exposure; it helps the vet gauge whether induced vomiting is still an option (usually only within 2 hours). Record video of odd behavior; subtle seizures look like zoning out or lip twitching.
