The "best" small service dog depends on the tasks needed, but top choices include Poodles (Miniature/Toy) for intelligence and low shedding, Corgis for trainability and alertness, Cavalier King Charles Spaniels & Bichon Frises for calm companionship/psychiatric support, and Yorkshire Terriers for alerts/emotional support, with other good options like Pugs & Pomeranians, all needing calm temperaments, obedience, and good health for public access.
Beagles, Miniature/Standard Schnauzers, Australian Shepherds, and Border Collies come to mind. But depending on your psych condition, I think Beagles or Standard Schnauzers would likely be your best bet.
Labs are for sure the best option, if you do want something small than perhaps a cavalier or a papillon, or a miniature poodle.

The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, representing 3 days (overwhelmed/hiding), 3 weeks (settling in/testing boundaries), and 3 months (feeling at home/bonding) to help owners manage expectations and provide patience, routine, and a calm environment, understanding that anxiety is normal as they decompress from a stressful past. It's a framework for recognizing stress and fostering trust, not a rigid timeline, but it helps owners understand why a new dog might seem timid or act out initially.

The Border Collie is widely recognized as the dog breed with the highest "IQ," consistently ranking first in intelligence studies for their exceptional ability to learn commands quickly (under 5 repetitions) and obey them (95%+ of the time).

#3: Cavalier King Charles Spaniel

Emotional support animals provide companionship and don't need any specific training. ESAs aren't covered by the Americans with Disabilities Act (ADA). Service animals are. ESAs offer comfort to individuals with anxiety, PTSD, depression, and other mental conditions.
To be considered a Service Dog, a dog must be individually trained to perform a job or task relating to your disability. Be aware that there is no official organization that sets training standards in the U.S. You are not required to work with a trainer – the ADA allows handlers to train their dogs on their own.
Dogs that are easily distracted, uncomfortable being approached or touched by strangers, or are aggressive are not good candidates. Evaluating a dog's temperament is the first step in determining if it will make a good service dog.

Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
Keep introductions short by following the “three second rule”; count to three as the dogs sniff each other, say thanks or nice to meet you to the owner, and then excitedly call your dog away and continue your walk.
