Hi Erika, I want to make it a litttle clear about the weight issues on airplane. The weight issues are for human/person only. There is no weight issues for a guide dog and service dog that has exemption from transportation. My suggestion to contact the DOT asap to make sure that there is no rules for guide dog and service dog for weight issues.
