I HAVE A FEMALE LHASA APSO AND A MALE SHIH TZU THAT A WILL LIKE FOR THEM TO HAVE PUPPIES BUT NOTHING YET. THE LHASA IS 1 AND 9 MONTHS AND THE SHIH TZU IS A YEAR.
The best time to mate a female is after her second heat or after 2 years of age. When she goes into heat, mate her between 9-13 days after the onset of bleeding for the best results. It is not a bad idea to bring your pets to the vet for a check up. good luck, vetcare
