I took my dog to the vet to get his vaccines and health certificate. I am traveling to Puerto Rico in 15 days and i did not do the research before i took him. Once the papers had been filled out and the vaccines had been given the vet assistant tells me that i have to travel within 10 days. I called the airline and was told there wouldn't be a problem with them. But im still freaking out. Will i have to change my flight? Would those 5 extra days matter?
