According the the AKC, Chihuahua's should not weigh more then 6 pounds. I am 5 1/2 pounds right now. (The vet has me on a diet, I need to lose 1/2 pound) At the Boca Greens Animal Hospital in Boca Raton (where else?) Flordia, a Chihuahua named Pumpkin has undergone liposuction. She's doing well after having 12 ounces removed from her hips. Pumpkin is now down to a slim and trim 11 1/2 pounds. That is twice what I weigh right now! Maybe I'll look into lipo so I can go back to eating all my treats and sweets. This isn't Pumpkin, his name is Burrito and his brother's name is Enchilada. Since my name is Chalupa, we could open a Mexican restaurant.
