ELI5: do pups in a litter all share the same DNA like human twins?

Do multiple pups in litter (or any other animals born as several at a time) share identical genetic code like human twins?

I'm hoping for a true Eli5 and a deeper explanation as well.

They are more like fraternal twins, so they have as much in common genetically as normal siblings. Dogs release multiple eggs during ovulation, whereas humans usually release only one, which is why multiple births are the norm in dogs and not humans. It's also possible for there to be two or more fathers to a litter (this is fairly common in dogs, possible but less common in humans). In this case, the siblings would have as much in common genetically as half-siblings (same mother, different father).
