TEMECULA -- What began as a nightmare scenario, now looks as though it will be a story with a happy ending for one Temecula family that found itself in possession of tainted dog food -- and an extremely sick dog.

Mia Johnson of Temecula first noticed Roxy, the family's 5-year-old cockapoo, was sick the morning of March 22. The first time her dog vomited, she wasn't too concerned. But as the vomiting persisted through the day and evening, Johnson knew she had to get the dog to a veterinarian for help.

"She had never been sick before," Johnson said of Roxy. "She was throwing up, a lot -- about every hour and drinking tons of water. She was lethargic, too."

The dog's sudden illness came during the panic that arose after millions of cans of pet food were being recalled nationwide because of a toxic chemical that was making animals sick and sometimes killing them.

The day after noticing Roxy's unusual symptoms, Johnson took her to the Tri-City Veterinary Clinic in Vista where Dr. Kenneth Kalthoff evaluated the sick pet.

"When the news broke of the recall, it was huge. And then to have an actual case in your office, from a professional standpoint, was pretty extraordinary," Kalthoff said, adding that he knew the situation was serious. "We knew not to mess around."

Kalthoff said there are known treatments for more common poisoning, such as when animals accidentally eat rat or snail poisons. But he likened Roxy's condition to anti-freeze poisoning, which causes crystals to form in the kidneys and is usually fatal.

"There is no antidote for what we were dealing with," Kalthoff said. "It was all trial and error."

The treatment Kalthoff and his staff decided to pursue was to place the dog on intravenous fluids for one week in an effort to keep in Roxy's kidneys circulating. He prescribed anti-nausea medicine to calm the dog's stomach.

"No one knew quite how long it would take to get her back to normal," Kalthoff said.

While Roxy has been released from the clinic and is back at home with her family, the dog still receives daily injections to ward off any unforeseen kidney problems. It is not yet known if she has fully recovered or if there may be future complications.

But for now, the vet and the Johnsons are optimistic. Roxy, with shaved cuffs around both her front legs from where the needles were inserted during treatment, now seems healthy -- though a little bitter toward her doctor, whom she slyly tries to nip when he's not looking.

Roxy is not alone in her unlucky illness.

Menu Foods, which started the pet food recalls March 16, added several new varieties of previously recalled food brands. The company also said it is extending its recall to items made as early as Nov. 8 through March 6.

Dog biscuits made by Sunshine Mills of Red Bay, Ala., were included in the recall Thursday after inspectors traced tainted wheat gluten to the company. It's at least the fifth recall in three weeks of products made with tainted wheat gluten imported from China. Officials have found melamine, a chemical used in the manufacturing of plastic, in the gluten.

In all, Menu Foods has recalled dog and cat foods from 95 brands. At least five other pet food manufacturers have also recalled products. Stephen Sundlof, director of the FDA's Center for Veterinary Medicine, said last week that the recalls, as well as the investigation into the poisoning of thousands of dogs and cats, are nearing an end.

Sundlof said that over the last three weeks, the FDA has received more than 12,000 complaints from pet owners who believe their animals were affected by the tainted food. That number, he said, is more than double the normal amount of complaints the FDA receives in a year for all of the products they regulate.

Although anecdotal reports suggest that hundreds of pets have died as a result of the tainted food, only about 15 deaths have been confirmed to be related to the situation, authorities have said.

Johnson has contacted the FDA about her dog's sudden illness. She kept an uneaten portion of the can of the suspect dog food, as well as an unopened can from the same batch. She said once she receives the proper paperwork, she will send the dog food samples to the FDA for analysis that will assist in gauging the spread of the contaminated food.

The food fed to Roxy was Nutro Natural Choice's chicken, rice and oatmeal formula for puppies. Johnson said the lot numbers on the cans of food fed to Roxy were confirmed by the FDA as being among the batches being recalled.

"This is an enormous amount of tainted wheat gluten behind the recall," Kalthoff said. "It has affected expensive and inexpensive brands. Owners had no way of knowing the food they were feeding their animals would be bad."

Even with the veterinarian's comforting words, Johnson said she blamed herself for Roxy's misfortune.

"I went through a lot of guilt," Johnson said. "You just don't think something like this can happen to you."

Kalthoff said Roxy is the only animal he has treated for symptoms from the contaminated pet food. He added that he is unaware of other vets in the region who have had similar patients.

But for Johnson, her hope is that no other animals and owners suffer like Roxy did.

"My heart goes out to all those pet owners who have already lost their animals, or who are going through the same thing I went through," Johnson said. "My family and I are so grateful that Roxy is still here and we're optimistic she'll have a full recovery."
