Oh yes yes yes, I have a mini poodle shiatsu and a jack Russell pug cross, they have made an enormous difference and ate so intuitive Louis will sleep at my head when I'm really crook
I have 2 emotional support animals, a cat and a dog. The process to getting an emotional support animal or ESA is actually quite simple. First you have to have the animal and you have to have a psychiatric diagnosis and disability. From there, you ask your therapist or psychiatrist to write you a letter that details why you need the ESA and essentially "prescribes" you the ESA. They also should include your diagnosis, that you are a current patient of theirs, what the animal does to support you, and they should list the laws that go with ESAs. They should also sign the letter and include their licensing information on it. It's actually really simple to get it done.
I have a cat that knows when something is wrong with me, he got me out of a epileptic attack by bitting my chin, licks my face when I'm about to faint
We have 2 cats, one of which has adopted me. If I'm in tears or in pain he sticks by my side until i feel better.
