in the instructions you can put any information you like but p l e a s e add where this thing exists, its not required but you probably should!!! anyways on to some limitations, you CANNOT make it humungous (that being the default dog sized line being to the top of its front foot) UNLESS it is prehistoric & extinct!!! you can get as crazy as you want with your species, you can make it have a high rate of successful hunts or even make it a hypervore, but DO NOT make it overpowered, thats really unfair for other people!! about intelligence, your species can have simple languages (as in calls that mean different things), can live in packs, and can make simple tools but keep their intelligence below the point where they could make little tribes (you know who you are eeheeee) sorry that theres a lot of information to take in, i recommend you ignore whatever i just said and do whatever you want, if you violate a rule and theres no excuse ill remind you and you could fix it so dont worry
