will it be okay for my cat to have another dog companion.?

earlier i asked if it will be okay to get a female puppy kuvash. if i already have a french masstiff. and i got a lot of good advice. thnx. I got a cat a while ago before i got my french mastiff. SHe was gonna be put down, because the animal shelter didn’t want her to give birth to her kittens, so i took her, ahe had kittens, i sold then, got her spayed, and shes been livin the life ever since.she likes hunting wild rabbits, mice, birds and even rats!!! when i added my mastiff to my household it took her awhile to get useto, but finally she got over it and doesn’t mind her. Will it be okay to get another puppy, even though she doesn’t llike other dogs. She spends, the nighttime hunting and daytime sleeping on my bed, she s and outside cat. Do you think she’ll accept this big pup just like my mastiff or is two too much?
