There is no magic to what we do to help fearful dogs, however you define magic. It’s time, energy, and effort all resting on a nice bed of patience.
In order to survive every species has to have reason to crawl out of bed every morning, or evening if they’re nocturnal. If they can’t it’s an indication something is wrong, seriously wrong. If we have dogs who are not fearful an unwillingness or inability to eat or engage in something fun is a big red flag. Sure our dogs get old and slow down, but when they start refusing food or ignore invitations to go for a walk we start to dread the writing on the wall. Often we head to the vet. An otherwise healthy dog who is not interested in food or doing anything that dogs typically enjoy doing, is in trouble. No magic is going to help them, we are.
First we eliminate any medical reasons for a dog’s behavior. An injured or sick dog needs to be treated. Once we can be assured that they aren’t hurting we tap into their brain’s reward system and run with it. If we can’t do this using food or fun, we have to do something to make it easier for them to stop worrying about protecting themselves and find ways to help them out of the funk of despair and depression, both responses I don’t doubt dogs experience.
If we can lower the dog’s level of anxiety either by the management of their environment and/or the use of medications we need to do it. We need to take hold of the reins of a dog’s reward system and turn them into addicts for what we offer them. Once we do that it only looks like magic.
