Food Network Star Rachael Ray needs a new recipe, but this time, it's for how to keep her much adored pit bull Isaboo from attacking other dogs. The TV host is distraught over the future of her aggressive dog and fears she may have to be put to sleep, reports RadarOnline.

While being walked by a dog handler in New York City earlier this month, Rachael's beloved pit bull allegedly tore off another dog's ear before her handler could tug the pooch away, according to a report in the National Enquirer.

Luckily, a vet was able to repair most of the injured dog's ear and Rachael and her husband, attorney John Cusimano, offered to pay for all medical bills, reports RadarOnline.

Rachael herself has been injured during Isaboo's run-ins with other dogs. The New York Post reported that when Rachael tried to intervene in dog fight three years ago, she was bitten by the other dog. In that case, it seems as though the other dog started the brawl, but the Emmy Award winner fears that Isaboo's behavior eventually will go beyond aggression towards other dogs and become a threat to children or adults, reports RadarOnline.

American Kennel Club Canine Good Citizen Director Mary Burch recommends that Isaboo get an evaluation by a Certified Applied Animal Behaviorist (CAAB) or another experienced canine professional to help determine the severity, possible causes, and how to get the situation under control. When a CAAB is brought in, for example, the first step would typically involve the animal behaviorist accompanying Rachael and Isaboo on a walk where they're likely to encounter dogs so that the behaviorist can better assess the situation

Isaboo, who Rachael sometimes calls 'Baby," has made guest appearances on Everyday with Rachael Ray. The dog also appears with Rachael in ads for Nutrish, the chef's line of dog food and treats. Back in August, Rachael told Paw Nation all about her deep connection with Isaboo and her former dog Boo: "They've taught me so much about life and the capacity an animal has to offer unconditional love."

While Rachael clearly adores Isaboo, her pooch's aggression can have several causes and may be based out of fear. "Aggression can occur when dogs are protective of their owners (and owners reinforce the aggression), or when dogs are not properly socialized from an early age," says Burch.

But, there's hope for difficult dogs like Isaboo. Depending on the severity of the situation and the causes, it could take just several weeks or even just a few months for both owner and dog to learn how to keep antagonistic behavior under control, especially when she's in the presence of other dogs. "An animal behaviorist will spend a good portion of time training the person who is at the other end of the leash, in this case, Rachael and her husband," says Burch.

We wish Rachael the best of luck with Isaboo. What do you think about other, more vicious dogs? Do you believe that even the most aggressive dog can be rehabilitated or are some beyond hope."

Tell me about your dog's personality.
My dog is very outgoing. She absolutely loves people and animals, and loves to show. She's also a very obedient dog. Though she does get very upset when we're showing other dogs. She definitely has some jealousy in her!

What is your dog's favorite treat?
Liver! She loves to eat liver! Though she pretty much eats anything. We'll make her liver as a treat when she's showing. She loves to eat chicken breasts too.

What is your dog's best trick?
She doesn't do any tricks, but she thinks she's a human. She's appalled to think that she's a dog. Many people call her a "pole dancer" because when she's getting ready to go in the ring, she climbs up the grooming arm pole. She always does this!

What's your dog's weirdest quirk?
When we're with other dogs in the ring she gets so jealous that she pouts. She doesn't bark -- she's definitely not a barker -- but she does get very mad. She'll sit there and watch the other dog's every single move. Then when we come back to her, she'll be so mad that won't even look at us for a few minutes!

Today, the American Kennel Club their 2009 registration statistics revealing the top 10 most popular dog breeds in the country. What's the secret to being popular? For dogs in the United States, it's all about safety.

Several of the dog breeds on the list are known for their hard work in keeping the country safe through border patrol, bomb and narcotics detection and searching for missing persons.

Put your paws together for the Labrador retriever who took the title as the #1 most popular purebred in America for the 19th year in a row.

Bumping the Yorkshire terrier out of the number two spot, the bold German shepherd is now the second most popular dog in the nation for the first time in over 30 years.

"Labs have been America's top dog for nearly two decades due to their loyal and gentle nature," said AKC Spokesperson Lisa Peterson. "But the German Shepherd Dog has gained ground recently, quite possibly due to the increased attention they receive for their security efforts at home and abroad."
