Clerics of certain faiths (most often nature-based ones) have access to a series of spells to Enthrall Animals. With a lengthy casting and a failed saving throw, the cleric can bond one or more animals to them for the rest of the creature’s life. The spell grants them an incredible rapport and, even without their own skill in training animals, the cleric is able to teach the animal various tricks and tasks, making them a more useful companion.
For many clerics, this is a means of attracting and connecting with a useful animal companion; a pet and helper. Some within the Brotherhood of the Bear will also raise animals for sale, or to give as gifts to those who will care for them. Priests of the Merry Marksmen are less likely to do so, as they do not like to train their beasts for hunting. A Golden Arrow may enthrall a dog or mountain lion, and may hunt with that animal, but the animal will not be trained to the hunt; rather, they will hunt free of training, and the cleric will hunt with them.
