Goblin dog as animal companion. Is it posible?

[PochiPooom]

When I read the ROUGH RIDER I wanted to play a druid goblin with a goblin dog as his aninmal companion

Rough Rider:
"You are especially good at riding traditional goblin mounts. You gain the Ride feat, even if you don’t meet the prerequisites. You gain a +1 circumstance bonus to Nature checks to use" Command an Animal on a goblin dog or wolf mount. You can always select a wolf as your animal companion, even if you would usually select an animal companion with the mount special ability, such as for a champion’s steed ally."

Is there a posiblity to get a goblin dog? or this feat can be only used situecional if you find one?

Is it possible? Yeah sure.

One animal companion shows up in a module and it is a modified version of a base animal with its own abilities.

The Wolf Animal companion states: "Your companion is a wolf or other canine creature, such as a dog"

So you can call your companion a goblin dog, it just uses the stats listed for the animal companion.

As of right now : no, a true goblin dog is not an option.

I suspect with goblinses being the only ones able to tolerate the beasts, it's too niche for core.
It's very likely they'll show up later, but for now you'll have to go with the wolf, or houserule a gobbodoggo if in a home game.
