Is Liquidambar styraciflua 'Worplesdon' toxic to dogs?

Mildly. The ASPCA lists liquidambar styraciflua 'worplesdon' 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. Not individually listed by the ASPCA, so its status is uncertain; treat with caution and verify with a vet. As a Liquidambar styraciflua cultivar, foliage is not known to be seriously toxic, but any spiky seed balls present a physical hazard to paws and may cause mild GI upset if chewed. Do not assume pet-safe.

As a Liquidambar styraciflua cultivar, foliage is not known to be seriously toxic, but any spiky seed balls present a physical hazard to paws and may cause mild GI upset if chewed. Do not assume pet-safe. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to liquidambar styraciflua 'worplesdon'.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
