 Vet check?
Besides the liver function, has a vet checked her? Has the pup gained/lost weight? Trachea fine? Mouth/teeth fine? No other structural component issues?
With such a small dog, can you back down the formula a wee bit at a time so she gets hungry. She may not need the extra calories enough to try new foods. If petite puppies are like petite children they can sustain themselves too easily on less nutritive calories and refuse other foods. For small children the offender is often fruit juice. |
