They lay there eggs on milkweed leaves.

Yes. Although Common Milkweed (Asclepias syriaca) is rarely found on U.S. lists of allelopathic plants, extracts from its roots have been found to reduce the germination rate and seedling growth of field corn.
Milkweed pollen is not much of a problem but some people have a contact allergy to the leaves and sap.
Some people are sensitive to the leaves and sap but the plant is not contagious.

Milkweed is toxic but I don't know of any dogs that were interested in eating it.
Yes, milkweed contains a toxic sap that can cause skin irritation or an allergic reaction when touched. It is best to handle milkweed with gloves to avoid any potential skin irritation.
they eat the leaves of a milkweed plant
Milkweed is famous for being a virtual cafeteria for a large number of insects to feast upon. Perhaps the most beautiful and well-known is the monarch caterpillar, which becomes the monarch butterfly. The monarch caterpillar chews along the edges of leaves. Aphids are also found on milkweed, and tend to feed in large groups on the leaves and stems. The blue milkweed beetle feeds on milkweed and can be responsible for holes in leaves. The four-eyed milkweed beetle is another beetle that eats milkweed and can cause holes. This beetle is red with black spots. Finally, herbicides can cause damage to leaves of milkweed. To take a positive view, holes can be a positive sign that the milkweed is supporting a wide range of insects and butterflies who are dependant on this food source.
The monarch butterfly must lay their eggs on milkweed plants (Asclepias ), and the swan plant is listed on wikipedia as a type of milkweed. Most plants in the milkweed family produce flowers which the monarch can feed on. The caterpillars of the monarch butterfly can only eat leaves from plants in the milkweed family and will die without this food source. The milkweed plant is known for it's white milky sap, which contains alkaloids, latex, and several other complex compounds including cardenolides. Some species are known to be toxic. The caterpillars are immune to the milkweed sap and actually make themselves poisonous by eating it. The butterfly retains the milkweed poison as a defense against predators. Both the monarch caterpillars and the monarch butterflies use bright color patterns as a warning that they are dangerous to eat.

The leaves are not in it but the sap is.
What causes the sap on a Linden tree? and what can I do?
Milkweed poison is harmful to sheep, cattle and sometimes horses, especially when eaten in bulk.
