How do you take care of a 2 month old chihuahua?

Answer 1

At 2 weeks the puppy is far too young to leave it's mother, so it's really the mother dog you should be looking after , then she'll care for the pup. If that isn't an option I recommend that you contact a veterinarian, as that pup will require detailed and special care.

Answer 2

For the next several weeks, the only thing your puppy will be able to eat is milk - you should get some puppy milk replacer and be prepared to bottle-feed your puppy every 4-6 hours. Ideally, at two weeks of age your puppy should still be nursing from his mother, which means you don't need to feed your puppy anything - just feed the mother high quality nursing dog food (usually puppy chow is recommended).
