Can a dog get pregnant from tiger?

No, a dog cannot get pregnant from a tiger.

Here's why:

* Different species: Dogs and tigers belong to different species and are genetically incompatible. This means their chromosomes don't match up, preventing fertilization.

* Reproductive anatomy: The reproductive systems of dogs and tigers are designed for their own species.

* Behavioral differences: Dogs and tigers are also behaviorally incompatible. They have different mating rituals and instincts.

In short, interspecies breeding between a dog and a tiger is biologically impossible.
