Q. 1 wo. puppy born smaller than the rest, so is not able to drink from mom. Very tiny, unable to gain weight and cries a lot...

A. There is usually a "runt" puppy of the litter that tends to be smaller than the rest, usually because he cannot or does not get enough milk from mom. Be sure to read the amount to feed on the formula you are using as young puppies will need to be fed a lot several times a day (and night) to allow for their rapid growth. However, if you are bottle feeding the puppy and he is still not gaining weight compared to the other puppies, he may be experiencing a failure to thrive. This can be caused by a number of things ranging from problems with anatomy (such as a cleft palate or opening in the top of the mouth), or problems with digestion and energy. If this is the case, having your local vet examine him for any problems is best to helping get him back to growing well with his brothers and sisters.
