A dogs love language is TREATS! It's not hard to please a dog. The way we as humans make our dogs feel loved is mostly with the food & treats we provide them with.
It's a good idea to give your dog a healthy reward several times per day. Treats encourage good behavior and also make your dog feel very loved. They can also aid in raising an obedient dog.
Using small healthy treats regularily to enforce good behavior is the best way to train your dog to understand exactly what you want from them. For a big ask, like a trick or an important command, use more enticing & high value treat.
It's important to be consistent with treats so it becomes a communication tool, one your dog understands!
