What's the best food for my teacup chihuahua puppy's health?

I never recommend Blue Buffalo, it's actually a terrible food. Hill's Science diet is perfect for Mia, it's an excellent brand of food. I do not recommend switching her food. The wet food is fine, but you can mix in some dry food as well. I hope this helps!

Personally, I really like Royal Canin's line of puppy foods - they even have a breed-specific diet for Chihuahuas :) Other good options would include Purina Pro Plan and Hills Science Diet. Whatever brand you choose, make sure to feed Peaches the puppy version the entire time that she's nursing, since she will need the extra calories to make milk for the puppies.

I recommend a small breed diet and to stick with one of the higher quality brands. I like Royal Canin because the diets have high quality, easy to digest protein and contain an excellent fiber blend. Most pets on this diet will have great stool quality and minimal amounts of stool because there's not a lot of filler. They actually carry a line for Chihuahuas. I also like Purina Pro Plan. Coco should eat twice a day and should eat puppy food until he is 1 year old. I hope this helps.

I would recommend a food intended for small breed dogs. The three brands I prefer when choosing a food are Hill’s, Royal Canin, and Purina. I think any of these would be a good choice. Additionally, if you are unsure of the age and history of your dog I would recommend taking her in to be examined by your veterinarian. You vet will be able to give an estimate of Bella’s age and recommend appropriate vaccinations as well. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Dogs should be fed an age appropriate diet, either a puppy food, maintenance diet, or senior blend. The best dog food companies are Hill's Science Diet, Royal Canin, & Purina. You can not go wrong choosing one of these. Thank you for using Petco Pet Education Center, formerly Petcoach.

Commercial diet of good quality (Royal Canin or Hill's puppy food) is the best option up to twelve months of age. Then you can switch to adult food. Feed her twice daily. As treats it would be ideal to use vegetables like carrots for example. These would be very healthy and not fat at all.

In general, grain free food is not recommended due to a potential link with heart disease. I recommend to feed a brand like Royal Canin Chihuahua Puppy (it's ok that he is a mixed breed) or their regular small breed puppy formula. Purina ProPlan also carries small breed puppy diets. The amount to feed is on the back of the package. I hope this helps and please feel free to post any additional questions.
