Pet's info: Dog | Yorkshire Terrier | Female | unspayed | 3 years and 5 months old | 11 lbs

Hello I’m currently a dog owner of a two yorkies. Male and female. The female yorkie has already been pregnant three times. But my mom wants to continue impregnating her. I keep telling her that it could be harmful for her since she’s already been pregnant three times. But her dad( which isn’t a vet) says that if they dogs don’t get pregnant they will get cancer. How many times can a dog get pregnant without it affecting her heath. And what are the consequences if she keeps getting pregnant?

No, it is absolutely untrue that if a dog doesn't get pregnant, they get cancer. Dogs should not be bred past five years of age, and they should not be bred multiple times a year. A good breeder knows to only breed a dog one every two years. It will be harder and harder on Nikki if she gets pregnant as she ages. You should tell your mom a vet told her to spay Nikki.
