MY YORKIE-POM GOT MATED WITH MY OTHER DOG

Question
MY YORKIE-POM IS 6LBS. AND 10 AND MY OTHER DOG IS PROABLY ABOUT 18 LBS. OR MORE. HE BROKE INTO HER PEN AND GOT HER 4 DIFFERNT TIMES.MY QUESTION IS SHOULD I BE CONCERNED ABOUT HER HAVING THE PUPPIES? HE IS ONLY LIKE 2 INCHES TALLER THAN HER, BUT WEIGHTS QUITE A BIT MORE THAN HER, HE WAS A VERY SMALL PUPPY UNTIL HE TURNED ABOUT 2. HIS MOM WAS A VERY SMALL MT. FEIST AND HIS DADDY WAS A CHIUARAH I CAN'T SPELL THAT WORD. HE GOT HER ON AUGUST 8 THANKS

Answer
How did he tie with her four times if he broke into her pen?

I would be concerned about a female that small birthing that litter. My advice would be to spay her, then you do not have to worry about unwanted litters now, or forever! And no more pen breaking from your male (especially if you neuter him too!)

Good luck!
