Lymphoma in Dogs

Canine lymphomas are a diverse group of cancers, and are among the most common cancers diagnosed in dogs. They collectively represent approximately 7-14% of all cancers diagnosed in dogs. There are over 30 described types of canine lymphoma, and these cancers vary tremendously in their behavior. Some progress rapidly and are acutely life-threatening without treatment, while others progress very slowly and are managed as chronic, indolent diseases. Lymphomas may affect any organ in the body, but most commonly originate in lymph nodes, before spreading to other organs such as the spleen, liver, and bone marrow.

What is lymphoma?
The term “lymphoma” describes a diverse group of cancers in dogs that are derived from white blood cells called lymphocytes. Lymphocytes normally function as part of the immune system to protect the body from infection. Although lymphoma can affect virtually any organ in the body, it most commonly arises in organs that function as part of the immune system such as the lymph nodes, spleen, and bone marrow. By far the most common type of lymphoma in the dog is multicentric lymphoma, in which the cancer first becomes apparent in lymph nodes.

Other common lymphomas in dogs include cutaneous lymphoma (lymphoma of the skin), alimentary or gastrointestinal lymphoma (lymphoma of the stomach and/or intestines) and mediastinal lymphoma (lymphoma involving organs within the chest, such as lymph nodes or the thymus gland).

What causes lymphoma in dogs?
Unfortunately, the cause of lymphoma in dogs is not known. Although several possible causes such as viruses, bacteria, chemical exposure, and physical factors such as strong magnetic fields have been investigated, the cause of this cancer remains obscure. Suppression of the immune system is a known risk factor for the development of lymphoma in humans. Evidence for this includes increased rates of lymphoma in humans infected with the HIV virus or are on immune-suppressing drugs following organ transplantation surgery. However, the link between immune suppression and lymphoma in dogs is not clearly established.

How is canine lymphoma diagnosed?
The best way to diagnose lymphoma is to perform a biopsy. A biopsy is a minor surgical procedure to remove a piece of lymph node or other organ affected by cancer. The most common methods for lymph node biopsy are Tru-cut needle biopsy, incisional wedge biopsy, or removal of an entire lymph node (excisional biopsy). The larger the biopsy sample, the better the chance for an accurate diagnosis of lymphoma.

We routine perform biopsy procedures to diagnose canine lymphoma at the Purdue University Veterinary Teaching Hospital (PUVTH). Dogs are placed under heavy sedation or general anesthesia to perform a biopsy. Although discomfort associated with this procedure is typically minimal, we often prescribe oral pain medication afterwards just to be sure your dog is comfortable following the biopsy.

How is canine lymphoma treated?
The most effective therapy for most types of canine lymphoma is chemotherapy. In some cases, surgery or radiation therapy may also be recommended. There are numerous chemotherapy treatment protocols for dogs with multicentric lymphoma. As discussed below, most dogs with lymphoma experience remission of their cancer following treatment, and side effects are usually not severe. Currently, the protocols that achieve the highest rates of remission and longest overall survival times involve combinations of drugs given over several weeks to months. The protocol we use as a “gold standard” for the treatment of canine multicentric lymphoma is a 25-week protocol called UW-25. It is based on a protocol called CHOP that is commonly used to treat lymphoma in humans.

The UW-25 protocol may not be appropriate for all dogs with lymphoma. Different types of lymphoma may be treated with different chemotherapy drugs. For instance, the most effective drug for cutaneous lymphoma is thought to be lomustine (CCNU). The veterinary oncologists and oncology residents at the PUVTH will help you decide on a chemotherapy treatment protocol that is appropriate for your dog.

A Zoney, a Cross-Breeding Between a Zebra and a Donkey, Born at Crimean Zoo

A zoo in the Black Sea peninsula of Crimea has welcomed its latest arrival – a "zonkey", which was born after a lonesome zebra got intimate with a donkey.

Named Telegraph by keepers at the Taigan zoo park in southern Crimea, the foal's head and body are the solid brown of a donkey but his legs have the characteristic black stripes of a zebra.

Born last week, "Telegraph is very popular with visitors" who can watch him romping around with his mother, according to zoo director Oleg Zubkov.

Cross-breeding between zebras and other members of the equine family is not unheard of, although it is rare that the zebra is the mother.

But the breeding of zonkeys or other hybrids is normally frowned upon by the zoo community.

"Such things don't happen in civilized zoos, but can occur at private zoos or on farms," said Anna Kachurovskaya, a spokeswoman for Moscow Zoo.

"This sort of marketing is not justified or scientific ... zoos are for preserving wild species, that is one of their most important goals."

Zubkov said Telegraph's mother, who had not had a mate for a long time, was lonely and uncomfortable in her enclosure at the private zoo founded two years ago about 20 miles from Crimea's main city Simferopol.

"So on the advice of a zoologist we moved her in with several other hoofed animals and she really liked the donkey. As a result of their affection for one another we've gotten Telegraph," Zubkov said in an email to AFP.

Telegraph was named after a local newspaper which recently celebrated its fifth anniversary.

Russia seized the Ukrainian peninsula of Crimea in March in a move hotly contested by Kiev and the international community.

Brooklyn, New York Residents Set Up "Wall of Shame" for Messy Dog Walkers

Dog walkers who don’t clean up after their pets on one Brooklyn street could find themselves in for a surprise nastier than the messes their pooches leave behind, thanks to a group of fed-up residents.

The South Oxford Street Block Association said on its Facebook page that it is setting up an online “wall of shame” of photos and videos of dog owners who don’t pick up after their pets on walks.

The group's president, Abby Weissman, already posted surveillance footage of a woman walking off after her dog stopped to do its business by a tree box on a sidewalk.

Weissman encouraged other members of the group to be on the lookout for more scofflaw dog walkers and to send in similar photos and videos.

“There is no excuse for this behavior,” Weissman said in a Facebook post. “If you can’t clean up after your dog you shouldn’t have one.”

Some residents in the neighborhood said they supported the idea.

“I am with y’all all the way (about) catching dog-walkers leaving their poop on the ground,” one longtime Fort Greene resident said in a post to the group’s Facebook page. “Oh does that drive me nuts.”

Under city law, dog owners who don’t pick up after their pets could face a $250 fine.

Esteemed NIH Scientist Crushed Roommate's Skull with Hammer in a Fight Over a Dog

Rockville, Maryland - A longtime scientist from the National Institutes of Health http://www.nih.gov/ is behind bars, accused of trying to kill his female roommate with a hammer. Police say the attack started because of a fight over a dog.

Timothy Oliver, a longtime scientist from the National Institutes of Health is behind bars, accused of trying to kill his female roommate.

On Aug. 4, Timothy Oliver, 68, of Rockville, left his dog, a 3-year-old Maltese, in his roommate’s care while he was at work. Around 9:30 that evening, Oliver received a blitz of frantic phone calls; it was his roommate reporting a car had run over his beloved pet in the condo parking lot.

According to charging documents filed in Montgomery County District Court, that roommate, whom ABC 7 News is not identifying, told bystanders, "He [Oliver] is going to kill me."

Oliver raced to the Metropolitan Emergency Animal Clinic in Rockville, where his roommate had taken the dog. Staff there attempted CPR, but the animal's injuries were too severe for resuscitation. The Maltese died shortly after arriving. Oliver placed the dog's body in a cardboard box and took it back to his condo along 6000 block of California Circle.

Feelings inside the first-floor unit quickly became tense. Oliver's roommate reportedly attempted to explain what had happened, prompting Oliver to start pacing around the condo. Oliver then allegedly retrieved a hammer from the kitchen, stormed toward his roommate, and hit her repeatedly in the head with the blunt-force object, cracking her skull.

"Are you serious? Oh my God! I didn't know that," neighbor Leila Neza said.
Following the attack, Oliver allegedly kicked his roommate out of his unit, leaving her unconscious on the sidewalk with a depressed skull fracture.

"It’s hard for me to believe,” said Mary Krause, who lives directly next door. "His action went from bad to worse. You don't attack somebody over something like that."

An 809 Pound Tiger Shark Caught in the Gulf of Mexico, Was Cooked and Served to More Than 90 Poor and Homeless Texans

Corpus Christi, Texas - An 809-pound tiger shark caught in the Gulf of Mexico earlier this month has been cooked and served to more than 90 poor and homeless Texans.

Timon's Ministries in Corpus Christi set up the donation of about 75 pounds of shark meat. Executive director Kae Berry tells the San Antonio Express-News that the 12-foot, 7-inch shark was the biggest fish ever donated to the center. A volunteer chef breaded and baked the meat.

Fisherman Ryan Spring, of San Antonio, had said he caught the shark after reeling it in for more than seven hours.

"It was like playing tug-of-war with a giant," Springs told KSAT-TV. "He’s pulling us and the water is just slapping against the back of boat. It was like a scene from the movie 'Jaws.'"

He said reeling in the giant predator marked the end of an epic battle.

"It’s hard to explain this thing about a fisherman fighting a fish," Springs told the TV station. "You’re probably just talking to yourself but you feel like you’re talking to the fish and saying things you probably can’t say on TV."

Berry says the volunteer chef did a great job preparing the food and "most people really enjoyed it." And the center says there are enough leftovers to serve up some shark stew next week.

The newspaper said Spring's giant catch did not beat the Texas record for a tiger shark, which is 1,129 pounds caught in 1992 by Chap Cain, according to the Texas Parks and Wildlife.

The world record for a tiger shark catch is 1,785 pounds, which was caught in 2004 off the coast of Australia, according to the International Game Fish Association.

Crew Members from Coast Guard Station Cape May Rescue and 800 Pound Leatherback Turtle in New Jersey

Atlantic City, NJ -  A huge leatherback turtle got a second chance at life thanks to the Coast Guard and some animal experts in New Jersey.

Crew members from Coast Guard Station Cape May and the Marine Mammal Stranding Center in Brigantine rescued the approximately 800-pound turtle Saturday.

It had become tangled up in fishing gear 30 miles off South Jersey.

A good Samaritan aboard a recreational fishing boat spotted the distressed turtle and notified watchstanders at Coast Guard Sector Delaware Bay.

A boat crew from Coast Guard Station Atlantic City took a Marine Mammal Stranding Center crew member to the Station Cape May boat crew located near Corson's Inlet.

They traveled to the GPS coordinates provided by the Good Samaritan and located the entangled turtle.

Once on scene, the Station Cape May boat crew and the Marine Mammal Stranding Center crew member assessed the situation and worked to free the turtle from the fishing gear.

"Everybody was excited," said Petty Officer 2nd Class Nick Giannaris, the crewman who physically removed the entanglement from the turtle. "It was one of my better experiences being in the Coast Guard, just seeing the animal so close and helping marine life. Everyone was pretty energized about the whole experience."

Mt. Pleasant, SC - A Charlston, Doctor Who Left 9 Dogs in a Car, Has Been Charged with Animal Cruelty - His Bond Has Been Set at $90,000

A Charleston doctor has been charged with animal cruelty after police said he was found with nine dead dogs.

His bond was set at $90,000, but Bickerstaff bonded out sometime Wednesday evening.

According to a Mt. Pleasant police report, officers were called to the Mt. Pleasant Emergency Hospital for a report of animal cruelty.

Staff members told police that a man had come in with six dead Cavalier King Charles Spaniels, crated in the back of his Ford Explorer. Staff members told police the man said he thought the dogs had passed out.

“This is a medical doctor. This is not acceptable,” said the woman who called 911 from Mount Pleasant Emergency Vet. “He had asked, ‘So, leaving the windows open is not adequate?' No. Not when they're in kennels and they have full coats, and you have them two by two in each kennel.”

According to the report, staff members saw that the dogs were deceased and rigor mortis had set in. They also told officers that the dogs showed signs of disseminated intravascular coogulosathy (DIC).

According to the National Heart, Lung, and Blood Institute, DIC is a "condition in which blood clots form throughout the body's small blood vessels" that can block blood flow to organs.

Police were given a description of the man and were told that he claimed to be a doctor at East Cooper Hospital. Investigators identified the suspect as 64-year-old Charles Allen Bickerstaff.

The 911 caller at Mount Pleasant Emergency Vet said Bickerstaff told her he had to stop by the hospital to check on a patient.

According to an affidavit, investigators met with him on Monday and he confessed to putting his 8- or 9-year-old spaniel, Butler, along with eight other dogs into five crates in the back of his SUV.

Court documents identified the other dogs as Money, Lucinda, Drayton, Madeline, Shelby, Katie, Freddie, and Willis. Their ages ranged from 5 months to 9 years, documents show.

Bickerstaff told police he left the dogs in the vehicle while he performed his duties at East Cooper Hospital. The affidavit notes that temperatures that day ranged from 73.4 degrees to 82.4 degrees with a heat index of 90.9 degrees.

The affidavit also states the air conditioner was not on and the windows of the Explorer were not open. Another release from police notes that the dogs did not have food or water and that they were caged for over three hours.

Bickerstaff was charged Wednesday with nine counts of ill treatment to animals.

According to the U.S. News and World Report, Dr. Charles Bickerstaff is a gastroenterologist and is affiliated with several hospitals including Bon Secours St. Francis Xavier Hospital and East Cooper Medical Center.

The Charleston Animal Society released a statement Wednesday afternoon, highlighting the dangers of leaving pets in cars for any amount of time.

“The temperature inside of a car during spring and summer and early fall in South Carolina will rise so much, that for a dog, seconds can cost them their life,” said Dr. Sarah Boyd, director of shelter health and wellness at the Charleston Animal Society.

Boyd says it's a deadly misconception that dogs can handle heat. In fact, some are more sensitive than others.

“It doesn't take very long, minutes, for their internal temperature to rise enough that they don't just begin to pant but, their body will start having organ failure and their brain reaches such a high temperature that they will have a heat stroke,” said Dr. Boyd.

Dr. Boyd says the lesson in this tragedy is simple: if you decide to allow your pet to travel with you, they must be with you at all times.

“Even if you think you can just run in and run out, it happens and it could be you and it could be your dog,” Boyd said.
