Both ESAs and PSDs come with financial commitments, especially if you don’t already own a pet. While pre-trained PSDs can cost over $20,000, adopting and training a dog yourself with professional help is a more affordable option that also strengthens your bond. ESAs are less expensive since no specialized training is required, with the main costs being the animal itself and an ESA letter. However, if your ESA is a dog, basic obedience training is recommended for a smoother transition into your home.
