Diabetes is on the rise — but humans aren't the only ones suffering. Diabetes diagnoses are rising at an even faster rate among dogs and cats than their human companions, according to a recent national analysis of pet health.
The 2011 "State of Pet Health" report is based on data from more than 2.5 million dogs and cats that visited Banfield Pet Hospital facilities in 43 states.
"This kind of data has never been available before," said Jeffrey Klausner, a veterinarian and chief medical officer for the Banfield Pet Hospital chain, based in Portland, Ore. "We want to share it with professionals and pet owners."
Nationally, diabetes rates increased by nearly a third among dogs in the last four years and by 16 percent among cats. It is much more common among cats. By comparison, human diagnoses of diabetes rose 10 percent over the same period.

The surprisingly high incidence of diabetes, he said, stems in part from rising rates of obesity.
"We have increasing obesity in dogs and cats, just like in humans. It's no mystery how that occurs: overfeeding and lack of exercise."
How can you tell if your pet has diabetes? The most common signs are excessive urination, excessive thirst, and weight loss, despite a good appetite, according to veterinarians. Once diagnosed, managing this chronic disease can be time consuming, usually including twice-daily insulin injections, a change in diet and regular monitoring by a vet.
"Millions of pets are getting insulin twice a day," he said. "Dogs can be diabetic for years and do just fine." Cats can be somewhat harder to treat because they are smaller, and harder to find for the daily injections.

Overall, the most common problem among the animals was dental disease, the report said.
Problems with the teeth and gums affected more than three-quarters of dogs and two-thirds of cats, with symptoms ranging from gum inflammation and tartar buildup to tooth loss. When severe, oral problems can lead to bacterial infections that spread through the blood to other organs and may cause chronic disease or organ failure.
Other common health problems among companion animals, according to the report:
* Fleas and ticks. Tick infestation carries the risk of Lyme disease. The rate of flea infestation has also climbed steadily.
* Internal parasites. Most pets show no signs of infection, although puppies and kittens can become noticeably ill. Some of these parasites can be transmitted from animals to humans.
* Otitis externa, or an inflammation of the outer ear canal. This was the most common diagnosis among dogs and cats after dental disease. Prevention includes regular ear cleaning.
Another surprise in the data, Klausner said, was the rising popularity of Chihuahuas and other small dogs, like Shih Tzus and Yorkshire terriers, as larger breeds like Labrador retrievers and German shepherds decline in popularity.
That may be due to changing lifestyles, as an older generation of pet owners with suburban homes and large yards downsizes and focuses on travel, and younger, apartment-dwelling pet owners buy breeds that take up less space, the report suggested.
