Hello, I went to my mother in laws house today and she showed me a new puppy, only 3 weeks old and the mother was hit by a car last night. The puppy is chihuahua and she asked me if I could care for her because she doesn't have the time. My son passed away in January and I think she hopes this will be good for me. The puppy is so adorable but I'm afraid I don't have the right tools to care for her. I know she should be on mom's milk until 8 weeks or so, and that chihuahuas have a problem with low blood sugar. How can I help her with that? I got her the formula from pet smart but she wouldn't touch it, so I went back and got the science diet ground puppy food. I mashed it up with warm water and she lapped up a spoon full of the liquid. I put a warm cotton ball to her privates and she peed but no poop so far. I know to keep her warm, another problem is she has so many fleas. I'm afraid to bathe her because she might get cold, but I know the fleas can't be good for her. I can take her to the vet this coming Friday, my husband is a mechanic and that is payday. I'm hoping someone here can tell me how to care for her until then, I'm willing to put the time in just want to make sure I'm doing it right. Is it okay for her to be eating the puppy food/water mixture? What should I do about her blood sugar? Thank you.
