Caring for Your Western Hognose Snake in Nashua, NH

Western hognose snakes (Heterodon nasicus) are small, hardy, diurnal snakes native to the grasslands and semi-arid regions of the western United States. They are well known for their upturned "hog-nose," which they use to burrow through soil, and for their dramatic defensive behaviors, including hissing, puffing, and playing dead.

Western hognoses are fossorial (burrowing) snakes and spend much of their time underground. When properly housed and acclimated, they can make excellent pets for both beginner and experienced reptile keepers.

Adult Size and Lifespan

Adult size

  • Males: 14–24 inches
  • Females: 24–36 inches

Lifespan

  • 15–20 years with proper care

Housing

Western hognoses require:

Enclosure

  • Hatchlings and juveniles: 5–10 gallon enclosure
  • Adults: minimum 36 x 18 inches (40-gallon breeder equivalent)
  • Larger enclosures are always acceptable if temperature gradients are maintained

Recommended Layout

Be sure to include:

  • Multiple hides (at least one on the warm side and one on the cool side)
  • Branches or low décor for enrichment
  • A deep substrate to allow natural burrowing behavior
  • A shallow water dish large enough for the snake to coil inside

Fresh water should be provided daily.

Substrate

Because hognoses are burrowers, substrate choice is critical.

Recommended substrates:

  • Soil-based mixes (e.g., reptile-safe topsoil or commercial reptile soil)
  • Coconut husk or coconut fiber
  • Fine reptile-grade aspen shavings

Avoid:

  • Pine or cedar (toxic aromatic oils)
  • Large-particle substrates that may be ingested

Provide at least 2–3 inches of substrate. Soil substrates allow light misting to help maintain humidity; aspen does not retain moisture well and may require a humid hide.

Temperature

Western hognose snakes thrive in warm daytime temperatures with a cooler retreat.

  • Basking area: 90–95°F
  • Warm side: 80–85°F
  • Cool side: 70–75°F
  • Night temperatures: low 70s°F are acceptable

Heat can be provided using basking bulbs, ceramic heat emitters (CHE), or heat mats (always on a thermostat).

Use a thermostat and reliable thermometers to prevent overheating.

Lighting

Western hognose snakes are diurnal, meaning they are naturally active during the day.

UVB lighting is still an area of ongoing research in snakes, but studies and clinical observation show that diurnal species often demonstrate improved activity, better feeding responses, and more natural behavior patterns.

Recommended UVB:

  • 5%–10% UVB
  • Linear bulbs (T5 or T8) are preferred over compact bulbs

Bulb replacement:

  • Compact bulbs: every 3–6 months
  • Linear bulbs: every 8–10 months (replace even if visible light is still produced)

Humidity

  • Target humidity: 30–50%

Humidity can be maintained by lightly moistening soil substrate once weekly and providing a humid hide with damp sphagnum moss.

Never allow the enclosure to become waterlogged, as this promotes bacterial growth and respiratory disease.

Feeding

In the wild, western hognose snakes primarily eat amphibians. In captivity, they should eat frozen-thawed rodents.

Feeding Guidelines

Hatchlings: pinky mice every 3–4 days
Juveniles: appropriately sized mice as they grow
Adults: once weekly feeding
Prey size should be approximately the same width as the snake's body.
Frozen-thawed rodents are the  safest option. Snakes should be transitioned to rodents before purchase

Feeding Challenges (common in this species)

Western hognose snakes can be picky eaters, especially when young. Helpful strategies:
Scent prey with tuna juice or amphibian water
Warm prey thoroughly
Dip prey briefly in warm scented water
Offer prey with tongs and allow the snake to drink water droplets first
Purchasing a snake that has already eaten 3–4 rodent meals consistently greatly reduces feeding issues.

Venom Note (Important for Owners)

Western hognose snakes are rear-fanged and mildly venomous, but they are not dangerous to humans. Bites are rare and typically occur only during feeding mistakes. Reactions in people are usually mild and localized. Should you be bitten by your hognose, please seek medical attention.

Handling

Western hognoses are generally docile but easily stressed.

  • Allow several days to acclimate before handling
  • Start with short handling sessions
  • Always support the body from underneath
  • Handle close to the ground to prevent injury
  • Avoid handling for 24 hours after feeding

Defensive behaviors such as hissing or playing dead are stress responses, not aggression.

Common Medical Problems

Impaction

  • Can occur if substrate is ingested during feeding
  • Feed in a separate container when possible
  • Seek veterinary care if stools are infrequent or absent

Respiratory infection

Signs include wheezing, open-mouth breathing, and mucus or bubbles from the mouth or nose. Often linked to improper temperature, humidity, or air quality.

Poor appetite

  • Common in young hognoses
  • Often related to natural diet preferences
  • Persistent refusal to eat warrants veterinary evaluation

Stomatitis (mouth infection)

  • Fragile gums and teeth
  • Swelling, scabs, or discharge around the mouth are abnormal
  • Requires veterinary treatment

Preventative Care

Daily and weekly care should include:

  • Daily temperature checks
  • Weekly spot cleaning
  • Monthly full enclosure cleaning
  • Secure enclosure checks
  • Feeding and shedding records

A yearly veterinary wellness exam is recommended to monitor growth, body condition, and overall health. Fecal exams twice yearly are recommended.
