Use the coastal-path access just south of the Beach Street groyne. This entry covers the Cottesloe dog-beach stretch, ending at the Town’s southern boundary.
The Cottesloe dog beach begins on the southern side of the Beach Street groyne and continues past the Town of Cottesloe boundary. It is a designated dog exercise area, so dogs can be off lead provided they remain under effective control. Bring dog poo bags and keep an eye on your dog around the water, other dogs and beach users.
The best part for walkers is that the off-lead section keeps going. Mosman Beach continues the dog exercise area south for about 600 metres, and the dog-friendly stretch then carries on into northern Leighton Beach. It finally ends at the pedestrian railway footbridge - a very easy industrial looking landmark to recognise when it is time to turn around or clip the lead back on and walk on the shared path.
One important beach habit: don't let your dog eat or mouth anything washed up along the tideline. Blowfish can contain the powerful nerve toxin tetrodotoxin, while washed-up sea hares and sea slugs can also be highly toxic to dogs and may be hidden among seaweed. If you suspect your dog has chewed or eaten either, contact a vet immediately - don't wait for symptoms such as vomiting, drooling, wobbliness, tremors, seizures or breathing difficulty.
The upper coastal path is a good sand-free alternative, while the beach itself gives you the longer option towards Leighton. There are no public toilets at the Cottesloe dog beach, so plan ahead if you're staying for a while.
