Traveling with ESA (dog) in Mexico

Hi! I am heading to mexico and am wondering anyone else’s experience with having a dog there. I have to take my dog on the plane (not in the cargo) so, I discovered I can do that if I fly MX to MX. I am going from Tijuana Airport. All 3 airlines have different requirements for emotional support animals or animals in general. The cage size restriction is way too small for even my small min pin /jack russel mix… she is taller than 8" for sure. Any experiences you would like to share with airlines or in general. The 1st place we are going is Puerto Escondido. Thanks in advance!
