Can i bring a puppy on international flights without it's rabies vacc?

you cannot bring a 6 week old puppy on a flight

puppy must be at least 8 weeks of age, and have a health certificate from the vet, and all age-appropriate vaccines.

Since the puppy is too young for rabies, it would not be required.. but you wont be allowed to take the puppy aboard for at least 2 more weeks.

You shouldn't have a puppy at 6 weeks, take it back to the "breeder" and go on your trip. Puppies should stay legally with their mom and litter mates until 8 weeks old. A reputable breeder wait at least 10-12 weeks. No dog can go to a different country without being properly vaccinated.

The pup is a lot too youthful which you will have besides. NO you may not carry a dogs into the U. S. without a rabies vaccination certificates. in case you "chanced on" this dogs, how do you already know its age? you only "chanced on" this pup jointly as on holiday? i detect that not basic to have faith. in case you "already delivered the dogs to the Vet" then the VET ought to have responded YOUR QUESTIONS.

You shouldn't have a puppy that young, a puppy shouldn't leave mommy dog and litter mates until they are 8 weeks.
Also the puppy is too young to get his/her rabies and that is required to have a pup on a flight.

first of the puppy is suppose to be kept with the mom for 8 weeks which mean two months .and would you be able to take a 6 week old pup without vaccines on an airplane the puppy can get sick because of the airplane ride plus i don't think U.S will allow pup with no vaccines especially from a diffrent country.

My yorkie's parents were shipped overseas from the UK when they were 8 weeks old. Since the UK is very strict with rabies this could be a different case. However Mexico and the USA are on the same piece of land although it isn't quite the same continent. I would think it is possible or else how do pedigree breeders ship their puppies out to overseas buyers?

You ought to enquire at the relevant authority in Mexico. Each country has a set of rules for exporting dogs. Also you'll need to enquire at the USA regarding import requirements. Once you've got both ends fixed, you can ship your puppies.

In some countries expetriate service companies know all about this. Perhaps you could look out for companies of this nature in Mexico?

First off it's you shouldn't have a puppy at 6 weeks.Secondly, No you can't.
