Is Mayhaw toxic to dogs?

Crataegus aestivalis

Mildly toxic to dogs

Mildly. The ASPCA lists mayhaw as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Crataegus is not individually listed on the ASPCA toxic plant database, so a non-toxic claim cannot be asserted; treat with caution and verify with a vet. The fruit pulp is eaten and made into jelly, but as with other pome seeds the crushed seeds contain cyanogenic compounds, so keep pets from chewing large amounts of seed.

What to do if your dog ate mayhaw

  1. Remove any plant material from your dog's mouth and move mayhaw out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of mayhaw to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten mayhaw, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
