They are called sea hares because of the ear-like appendages at the front, actually a kind of giant sea slug, and yes they are toxic to dogs.

From the Fisheries WA web site:
Look out for dark blobs of slime that sometimes wash up on local beaches during late summer and throughout autumn. These unusual creatures are actually sea hares - a type of mollusc, closely related to sea slugs or 'nudibranchs'.
But be careful… when threatened, these slug-like animals may excrete a toxic purple ink that can irritate the eyes and can even kill a dog if eaten.
Sea hares get their name from the two fleshy tentacles that protrude from their head, which (with a bit of imagination) resemble hare's ears.
Grazing on algae, their black/brown colour (although some species have a dark mottled green pattern) acts as perfect camouflage, as they slowly crawl over the seabed.
Gathering in late summer, sea hares form a long chain to reproduce. As 'hermaphrodites', they can act as a male for the animal in front and a female for the animal behind at the same time! They then deposit long strings of up to 180 million eggs on the sea floor.
Sea hares only live for about a year - they die after laying their eggs.
