It really saddens me that the pet food industry has duped everyone into believing that our pets can survive on a single diet. That can't be any further from the truth. Dogs ( and cats ) need variety in their diets just as we do for optimum health. A sole diet has been proven to be nutritionally DEFICIENT and the "balanced and complete" statement is not only misleading but downright inaccurate. If you ate the same thing day in and day out you would eventually suffer from serious health problems and it's only common sense to conclude that your pet will as well.
I feel the same way and give Jessie a varied diet, but Purina did a study where they fed the same food to Labradors for about 13 years. The purpose of the study was to see if dogs that were kept in ideal body condition lived longer, which of course they did, but all the dogs were fed the same diet and lived fairly long life spans.

"When the study began, 48 eight-week-old Labrador Retriever dogs from seven
litters were paired within their litters according to gender and body weight and
randomly assigned to either a control or restricted-fed group. The control group
was allowed to eat an unlimited, or free choice, amount of food during 15-minute
daily feedings. Dogs in the restricted, or "lean-fed," group were fed 75 percent
of the amount eaten by their paired littermates.
All dogs were fed the same 100 percent nutritionally complete and balanced
diets (puppy, then adult) for the entire period of the study, from eight weeks
of age until death—only the quantity was different.
Study findings revealed that the median life span of the lean-fed dogs was
extended by 15 percent or nearly two years. Median life span (the age at which
50 percent of dogs in the group died) was 11.2 years for the control group
versus 13 years for the lean-fed dogs.
By age 10, only three lean-fed dogs had died, compared to seven control group
dogs. At the end of the twelfth year, 11 lean-fed dogs were alive with only one
control dog surviving. Twenty-five percent of the lean-fed group survived to
13.5 years, while none of the control group dogs lived to 13.5 years."
