Growth plate issues are not an issue in small breeds of dogs, they do not grow into gangly tall dogs unless their genetics says to do so. Spay or neuter at 3 months has been found not to be much of a problem in toys but I do not recommend doing the spay or neuter until at least 6 months of age.
Risks if you don't neuter is testicular cancer, prostate cancer, bladder issues, and even increase risk of rectal cancer. Unneutered males in a breeding program that is used for breeding don't seem to have these issues but an unaltered male should not be in a breeding program unless it is registered with a bona fide registry, has championships, meets the breed standard and especially for a male, be very outstanding for its breed. Otherwise neuter and enjoy your pet which is what you likely wanted, just a nice pet.
