Animal with thick body and course fur it burrows into the ground is related to rabbit?

The animal you're describing is likely a marmot.

Here's why:

* Thick body: Marmots have stocky, robust bodies, well-suited for digging.

* Coarse fur: They have thick, dense fur that helps insulate them in cold climates.

* Burrows into the ground: Marmots are known for their extensive burrow systems, which they use for shelter, hibernation, and raising young.

* Related to rabbit: Marmots are rodents, just like rabbits. While they are not directly related, they share a common ancestor in the rodent lineage.

Other possibilities, though less likely, could include:

* Paca: These are large rodents found in Central and South America with similar body shapes.

* Groundhog: These are also rodents, but they are more closely related to squirrels than rabbits.

If you can provide more details about the animal, such as its size, location, or any other distinguishing features, I can help you narrow down the possibilities further.
