I have been feeding my dogs 4-Health for a while and the dogs have done really well on it. Well, I decided that I wanted to improve on that a bit so I switched them to Taste Of The Wild. Since it's always a good idea to introduce any new food slowly, I mixed a bowl up for the chihuahuas that was probably 50/50 of each. The chihuahuas get free choice and have always maintained a perfect body weight. Well, that day when I got home from work I checked their bowl and found all of the 4-health scattered around in front of the bowl and most of the Taste Of The Wild GONE!! Those little doggies picked though their bowl and ate all the good stuff! So much for slowly introducing the new food! I really can't say I blame them though....that new food smells really delicious!
