Horses are herd animals and they will miss a friend that has been with them. They grieve too. Try to find another buddy for your horse, such as a goat, sheep, another horse, whatever you can afford. There are many rescue Horse places trying to find good homes for their rescues (check with your Vet or your nearest Animal Shelter). Maybe look into that. But a goat or sheep will do too or a small donkey.
Yes they can. As mentioned above make sure they have another animals company :) Although even with a replacement they may get sick etc
