how do endangered species deal with inbreeding?

Very carefully. Zoos and other facilities that are trying to increase breeding will track the family lines and will transport the animals to encourage the widest possible genetic diversity.

Very carefully.
If left to their own devices, inbreeding will likely be a problem, but with human intervention, we can help.
Basically we can create a healthy gene pool from 50 healthy individuals, and we can leave them be to reproduce on their own with 500 healthy individuals.
These are just general guidelines and doesn’t apply if there is already heavy inbreeding or all the individuals are already related. In any case, the more individuals, the better.

In addition to what others said, some species that live in environments that makes severe population reduction likely (eg, small islands) may have adaptions that makes inbreeding not cause much problems, such as the [Black Robin](https://en.wikipedia.org/wiki/Black_robin).
> All of the surviving black robins are descended from “Old Blue”, giving little genetic variation among the population and creating the most extreme population bottleneck possible. However, this does not seem to have caused inbreeding problems, leading to speculation that the species has passed through several such population reductions in its evolutionary past, and has lost any alleles that could cause deleterious inbreeding effects.

In captivity, their pedigrees are tracked, and breeding pairs are chosen to minimize inbreeding.
In the wild, Roll Tide!
