Service Dog Training for 4yo Dollin

Dollin's teachers have expressed that he is struggling in PreK. He currently is receiving physical, occupational, and speech therapy. Unfortunately, Dollin is falling a lot because his muscles and joints when stretched are not returning to nornal. His right hip is also turning in when he's running. This is causing him to fall. Dollin is also suffering extreme meltdowns, and is not able to self soothe . Lastly, he is really struggling with fine and gross motor skills, and hand eye coordination. Dollin's physical therapist has recommended a service dog to help place pressure on dollin to calm him down, to help break his falls and prevent injury, and to help with his motor skills and coordination. My family just doesn't have the funds to fully trained a service dog, so we are begging for help. We already have a dog that has passed an assessment to be trained but we can't start training till we raise the full amount. Thank you for taking the time to read this and help our family and Dollin.
