Solid Gold's "Just a Wee Bit" adult dog food is one of the best dog foods. I have three small chihuahuas and have them all on this food. They have shiny coats, clean feces, and amazing amounts of energy. One of my dogs is 14 years old and has been on this food for most of her life. She has NO arthritis, NO heart issues, and NO health issues in general. The vet says she is the most healthiest chihuahua he has seen in a while considering her age. I attribute her health to this food. It is rich in meat and contians no salt, preservatives, or fillers. You do have to be very careful and make sure you feed the correct amount. It is rich and can make them fat if not given the proper amounts. It is on the expensive side but well worth the buy. And because it is so healthy and rich in nutrients, you really end up not feeding as much. So the quantity you give your dog is much smaller then other dog foods because they don't need as much since it is so nutrient rich. Excellent dog food choice!!
