I just got a Mini Dachshund puppy yesterday he is 6 weeks old. I have a cat I have had since it’s birth that is 5 years old. And every time the puppies (I am puppy-sitting my puppy’s brotheR) are asleep and I am holding her, she will just stare at them. And then I was holding my puppy’s brother close to her and she just kept meowing because She’s in heat but the puppy got really scared. So is there anyway I can help them get along better?
