Eastern Hognose Snake
The western hognose's bigger eastern cousin, with the same upturned snout and theatrical death-feigning act. It is rear-fanged and mildly venomous, and it is a toad specialist that is rarely kept in captivity, so feeding is the real challenge. Some states protect it, so it must never be collected from the wild.

Overview
The eastern hognose is a small to medium, thick-bodied snake, typically 2 to 3 feet long and occasionally over 4 feet 1. The Maryland Zoo gives 20 to 35 inches and under a pound 2, and females are larger than males 4. It is named for its upturned, keeled snout, which it uses to dig through soil and moss 12. Coloration varies enormously, from patterned red, tan or yellow to solid black or gray 12.
Eastern hognoses are rear-fanged and mildly venomous. Enlarged rear teeth and Duvernoy's gland secretions help them subdue toads 1. Bites to people may cause mild local swelling or irritation, but they are not medically significant 1.
Why this guide is rated Advanced. Eastern hognoses are dietary specialists that eat mainly toads 14. They are rarely kept in captivity, and captive animals have been recorded living only up to about seven years 4. Their husbandry overlaps with the western hognose, so the setup guidance below draws on veterinary care sheets for that close relative 56. The diet section explains why feeding is harder.
Natural history
Eastern hognoses range across the eastern and central United States, from southern New England and the Great Lakes south to Florida and west to Minnesota, Texas and extreme eastern Colorado 1. They favor dry habitats with well-drained sandy soils, including open, sandy ground with woody debris and low cover, longleaf pine, dry oak–hickory forest, coastal dunes and fields near wetlands with amphibian prey 1.
They are active by day, especially when temperatures are moderate and humidity is high 1. Much of their time is spent underground 2. Wild hognoses eat mostly toads, and occasionally frogs, salamanders and small mammals 14. They tolerate toad toxins 14.
Their defense is legendary. A threatened hognose flattens its neck like a cobra, hisses loudly and makes bluff strikes. If that fails, it rolls onto its back, smears itself with musk, sticks out its tongue and plays dead 12. In captivity this display is a sign of serious stress. Maryland Zoo keepers take pride in never having seen it 2.
Enclosure
Setup guidance for the western hognose 56:
- Floor space over height. Hognoses live on the ground 6. Adult westerns need at least 20 gallons, with a minimum floor of 24 × 12 in 56. Eastern hognoses grow larger 1, so err on the generous side.
- Escape-proof lid. Clip it down, because hognoses push up on screens with their noses 56.
- Burrowing. Burrowing space is essential, plus at least two hides (warm and cool) 56.
- Water. A water dish, ideally big enough to soak in 56.
Temperature & lighting
Western hognose ranges from veterinary care sheets 56:
Heat with an under-tank heater or heat tape on a thermostat, and never use hot rocks 56. UVB isn't required, but low-output UVB can encourage natural behavior 56. Give 10 to 12 hours of light a day 56.
Wild eastern hognoses are mostly active from spring to autumn 4, with activity peaking in September and October 1.
Humidity
For western hognoses, vets recommend low to moderate humidity of about 30 to 50% 56. Respiratory problems are often linked to the wrong humidity 6. In the wild, eastern hognoses are most active on the surface when humidity is high 1, but they live in sandy, well-drained habitat 1. Provide dry substrate with a slightly more humid burrowing area or hide.
Substrate
- Only expert, clinic or hobby sources
Provide loose substrate deep enough to burrow in. For western hognoses, vets suggest 2 to 4 inches of aspen or a reptile topsoil–sand mix, and never pine or cedar 56. Hognoses tend to swallow bedding while eating, so feeding in a separate bin is safest 6.
Diet & supplementation
Wild eastern hognoses specialize in toads 14. Pet keepers can't supply wild toads safely or legally, so a captive hognose has to accept rodents. Western hognoses are routinely raised on pre-killed mice 56, and Chicago Exotics' tips for picky westerns include scenting a thawed pinky with amphibian scent or tuna juice 6.
Buy only captive-bred eastern hognoses that are already eating thawed rodents reliably, and ask the breeder for a feeding record. Chicago Exotics recommends buying a western hognose that has eaten three or four meals with the breeder 6, and that matters even more for this species. If a snake refuses food, see a reptile vet rather than offering wild-caught amphibians.
Feeding schedule for western hognoses: juveniles every 4 to 5 days and adults every 7 to 10 days, with prey about as wide as the snake's widest point 5. Tongs help, because hognoses strike from any direction 6.
Handling & temperament
Hognoses rarely bite people. Their hissing, hooding and bluff strikes are bluster 12. Start handling only once your snake is eating well, and support its whole body 5. Avoid handling during a shed or within 48 hours of a meal 5. If your snake rolls over and plays dead, it is severely stressed, so put it back and give it time 26. Wash your hands afterward: reptiles and feeder rodents can carry Salmonella 8.
Health
- Only expert, clinic or hobby sources
Common issues (based on veterinary guidance for the closely related western hognose)
- Feeding refusal, especially in young snakes 6.
- Impaction from swallowed substrate 6.
- Respiratory infections. Watch for wheezing, open-mouth breathing, frequent yawning or bubbles from the nose 67.
- Mouth problems. Hognose teeth and gums are fragile 6.
- Difficult sheds and retained eye caps 5.
When to see a vet
Schedule an annual exam to track weight 5. See a vet promptly for appetite loss, weight loss or breathing symptoms 56. Open-mouth breathing or an unresponsive snake is an emergency 9.
Breeding overview
Eastern hognoses mate mainly in spring and early summer. Females mated in autumn can store sperm until the following spring 4. They lay eggs, and gravid females spend more time on the surface than males 14. Because this species depends on toads and is protected in parts of its range 3, Novel Fauna does not recommend breeding it unless you have a reliably rodent-eating captive-bred line.
Legal & ethics
- Rests on a single source
- Never collect wild hognoses. The eastern hognose is a Species of Special Concern in Massachusetts and an Endangered Species in New Hampshire, where it reaches its northern range limit 3. Check your state's wildlife rules before you buy or move one.
- Rear-fanged. Some jurisdictions regulate rear-fanged snakes, so check your local exotic-pet rules.
- Choose captive-bred animals that are already eating rodents.
