My dog ate a lizard — is it dangerous?
Answered by our veterinary team
In India, dogs frequently eat small house geckos and garden lizards. Here's what you need to know:
Common small house geckos (chip-chip lizards)
These are generally not toxic. If your dog snapped up a small gecko, the most likely outcome is no symptoms at all. The lizard is not poisonous.
Main risks
1. **Parasites**: Lizards can carry Salmonella bacteria and various intestinal parasites (including Spirurid worms that can occasionally infect dogs). Most healthy, dewormed adult dogs have good enough immune systems to clear these without incident. However, puppies or immunocompromised dogs may develop digestive symptoms.
2. **Liver flukes (Platynosomum fastosum)**: In some regions of India (particularly south and coastal areas), lizards carry liver fluke larvae. Dogs that regularly eat lizards can develop liver fluke infection over time. This is more of a concern for repeated exposure than a single incident.
3. **Large monitor lizards**: India's monitor lizards (goh/goanna) have bacteria in their mouths and can cause serious bite wounds if the dog attacks one. The lizard eating the dog is more of a concern here than the other way around.
What to watch for after your dog eats a lizard
- Vomiting or diarrhoea in the next 24–48 hours - Lethargy or loss of appetite
What to do
A single small gecko is rarely an emergency. Monitor your dog for 24–48 hours. If symptoms develop, or if your dog regularly eats lizards, mention it to your vet and request a faecal parasite check.
