Deerog By: Will
Benificial or Detrimental
This mutation is more likely to be detrimental. It is more likely because no other dog will want to probably play with it. The antlers would also get in the way of the dog bending down. Also, it couldn't sniff the ground because the antlers would stop it.
If this deerog finds a mate, it will most likely only pass on only the dog part of the body. It will probably still pass on the deer antlers just because in order for the antlers to be passed on, it would have to be a dominant trait, so if it finds a mate, then the antlers will be passed on.
