They sell in smaller bags, so you can try out one brand and if your dog doesn't do well, you can switch over to something else that may agree with her system better.

With a small dog, you can buy a large bag of dog food at a good price and have it last a good while. www.dogfoodanalysis.com is a great way to look up brands of dog foods and how they break down as far as ingredients go, and then decide what's best for you.

If you can buy it at Wal-Mart, don't. Don't shop by price, I used to feed Purina Puppy Chow which called for Josie to have 6 cups a day. On Chicken Soup, she only needs 3 cups. So while I was paying almost twice as much for better food, it lasted over twice as long, and was much, much better for her (less pooping, shiny coat, lots of energy).

And you could always consider a raw diet.

Avoid:
Purina
Iams
Eukanuba
Pedigree
Science Diet
Ol'roy
Eagle Pack
Nutro
Royal Canin
And anything else that uses by-products, corn, wheat, or soy

If you are talking about dogs…….. They are the runts and the sickest of the litters, that Puppy Millers have named something cute to con buyers into paying extraordinary prices for ill-bred dogs

specify ur location a little more

And do some research. Yorkshire Terrier comes in ONE size - a two pounder is the same as a six pounder, there is no named or noticed difference (like there is in Schnauzers and Poodles.)

Anyone selling a "teacup" dog is selling poorly bred runt type dogs. You will NOT find one at a "decent price" because people who breed them are doing so to scam money from people who didn't bother to research. Period.

If you want a small Yorkie, find one from a reputable breeder. Or try a rescue group or shelter.

Yorkies and small dogs in general will cost well into the $900 range because they ARE hard to safely breed/whelp. They also have smaller litters.
