What are the most common sources of lead poisoning in dogs and cats?

Common sources include flaking old paint, small lead objects or components, discarded metal items, and environmental contaminants. If ingestion is suspected, bring the item to your vet for assessment.

What tests will the vet perform at the clinic?

Your vet will typically carry out a physical examination, blood count and biochemistry panel, urinalysis, and imaging such as X-rays or CT scans to check for metallic foreign bodies or signs of toxicity. Further tests may be arranged as needed.

How long does treatment and monitoring take before the pet is considered stable?

The monitoring period depends on the severity of poisoning and may span several weeks to months, involving multiple blood tests, imaging, and clinical assessments. Follow your vet's recommended recheck schedule.

How can I prevent lead poisoning in my dog or cat?

Keep pets away from old paint, discarded metal, and construction sites. Store small components securely and supervise outdoor activities. Consult your vet or an environmental professional if you have any concerns.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek Emergency Care Immediately

•Continuous or generalized seizures that will not stop
•Confusion, unresponsiveness, or loss of consciousness
•Unable to eat with signs of obvious dehydration

Schedule a Clinic Visit Soon (Within 24–72 Hours)

•Repeated vomiting or frequent diarrhea lasting more than one day
•Noticeably reduced appetite or changes in water intake lasting more than one day
•Unsteady gait or clearly worsening coordination

01What symptoms indicate something is wrong?

Lead poisoning commonly affects the gastrointestinal and nervous systems. Clinical signs vary in type and severity and often involve both the digestive and neurological systems.

Lethargy, dulled responses, or excessive drowsiness
Decreased appetite or noticeable changes in water intake
Repeated vomiting or frequent diarrhoea
Seizures, muscle tremors, or intermittent convulsions
Unsteady gait, poor coordination, or trembling
Seek veterinary care promptly if symptoms persist or worsen

Seek emergency care immediately if you notice the following symptoms:

⚠️ Continuous or repeated seizure episodes
⚠️ Altered consciousness (extreme drowsiness, unresponsiveness, or collapse)
⚠️ Inability to eat combined with signs of significant dehydration

02How should you assess the situation at home? Key observations and emergency criteria

Recording key information at home can help your vet make a faster assessment and prioritise care.

Note the time symptoms began and document any changes in behaviour
Observe and record the frequency of vomiting, its contents, and whether there is any blood
Record bowel movements — consistency, frequency, and the presence of blood or mucus
Track any changes in appetite and water intake, with timestamps
Use your phone to film any abnormal gait or seizure episodes for the vet to review
If ingestion is suspected, bring the suspected item or substance to the clinic
Arrange a vet visit promptly if symptoms do not improve or are getting worse

03How will the vet make a diagnosis? Common diagnostic tests

At the clinic, your vet will combine a physical examination with laboratory and imaging tests to assess the severity of poisoning and check for the presence of any foreign material.

Physical examination

assessing neurological status, pulse, respiration, and temperature

Blood count

evaluating blood cells, electrolytes, and any abnormal changes

Biochemistry panel

assessing liver and kidney function and metabolic markers

Urinalysis

helping evaluate kidney function and toxin excretion

X-ray

checking the gastrointestinal tract for metallic foreign bodies or other abnormalities

Advanced imaging (CT)

used in complex cases or when a more detailed assessment is needed

Attending a clinic with imaging and laboratory capabilities is recommended for a full evaluation

04What happens after diagnosis? Treatment, diet, and ongoing care

Treatment for lead poisoning involves acute supportive care and ongoing monitoring, along with identifying and removing the source of exposure to reduce the risk of recurrence.

Hospitalisation may be required during the acute phase for observation and supportive care
Your vet will advise on necessary interventions and schedule follow-up tests
Attend scheduled rechecks after discharge, including repeat blood work or imaging as needed
Neurological and digestive system recovery will be assessed during follow-up visits
Identify and remove potential sources of lead exposure in the home environment
Return to the clinic immediately if symptoms worsen or new signs develop

05What should you prepare before the vet visit? Key details to help your vet diagnose quickly

Write down when symptoms started and how they have progressed

List recent locations visited, foods eaten, and any items that may have been ingested

Bring any suspected ingested item to the clinic for examination

Bring a list of all current medications and supplements your pet is taking

Bring any previous test results or imaging scans for comparison

Prepare videos or photos to help the vet observe abnormal behaviour

Consider booking an appointment with a specialist clinic or referral centre early
