The Benefit Of Low Fat Pet Food In Dogs With GI DiseaseApril 27, 2012 Lipids are water-insoluble molecules that have many crucial functions in dogs. There are a variety of different lipids, but the only lipids that are routinely quantified in dogs are triglycerides and cholesterol. Hyperlipidemia refers to a state of abnormally increased blood concentrations of triglycerides, cholesterol or both. One indication for low-fat dietary intake in dogs with gastrointestinal disease is the management of dogs with hypertriglyceridemia with GI disease presumed to be due to or related to hypertriglyceridemia. The second indication is a group of dogs that have a normal serum triglyceride concentration, but have GI disorders resulting in difficulty to digest and/or absorb normal amounts of fat in pet food or dogs with lymphatic abnormalities. Hypertriglyceridemia is very common in dogs.1 In one recent study, 611 routine chemistry profiles in dogs performed at a private veterinary laboratory in Italy were evaluated and 33 dogs (5.4 percent) showed hypertriglyceridemia.1 Certain breeds have been identified as being much more commonly affected by hypertriglyceridemia. In a recent study of 192 healthy miniature schnauzers, 63 (32.8 percent) had hypertriglyceridemia.2 Definitive differentiation between primary or secondary hypertriglyceridemia is sometimes difficult, but is based on …

Feline Heartworm’s A Different AnimalApril 25, 2012 A recent study at Auburn University has shown us a new side of feline heartworms. Dillon and Blagburn, with the financial backing of Pfizer Animal Health of New York, performed an amazing study1. They infected three groups of cats with heartworm larvae. The first group was untreated to see what would happen from natural exposure. The second group was given ivermectin at the time in the life cycle that would kill the immature adults but not the adults. This group showed the pathology that occurs when the 2-inch-long immature adults die; the pathology that occurred was only due to immature adults, not to 6-inch-long adult worms. The third group was infected while receiving selamectin. This group was to demonstrate the efficacy of this drug in preventing heartworm infections; its high efficacy was clearly demonstrated. The following is a synopsis of what we now know about heartworm disease in cats. Life Cycle When a mosquito bites a cat, third-stage larvae (L3) are deposited on the cat’s skin. Within minutes they enter the subcutaneous tissue through the bite wound. The L3 molt within a couple of days to fourth-stage larvae (L4). L4 migrate …

Is It Who Pulls The Trigger?April 6, 2012 (Note: Due to the recent disturbing report of Nick Santinos’ suicide after euthanizing his pit bull, Rocco, I have reissued this blog from last year…) You may have heard it before, the reasoning that guns do not kill people, the people who pull the trigger do the killing. That’s pretty black and white in this instance…a gun sitting in a drawer or under a pillow isn’t going to go hurt someone on purpose; it’s not a living thing with thoughts, actions, and reactions. So what about a parallel, but altogether different, issue of banned dog breeds? Yes, we all know that it’s becoming more commonplace for laws to be discussed and passed that ban certain dog breeds of notably bad reputations, such as pit bulls. On the one hand, you may know a person or family member who has suffered due to a dog attack. On the other hand, I have never met a more loyal group of dog lovers than owners of pit bulls, and they would never trade their breed for any other! They argue that like guns, it’s the people who own the dogs that are calling the shots and have the responsibility …
Pelvic Limb Lameness: Palpate Early And OftenApril 5, 2012 Contrary to popular perception, not all pelvic limb lameness in dogs is joint-related, i.e., a “bad hip” or a “blown cruciate.” Definitive diagnosis is crucial, especially before pursuing surgery for the presumptive problem.1-5 Advanced imaging can help, as can arthroscopy, but neither method reveals soft tissue pain as a common source of the tension and altered gait in dogs. Only hands-on touch and informed palpation can “image” this source of discomfort and possible precursor to cruciate rupture. In light of this uncertainty of why a dog unweights a limb or displays caudal end weakness,6 clients who call a referral center for an evaluation are surprised when the receptionist asks them to set aside a surgery date.7 Even with a busy cutting schedule, why wouldn’t an orthopedic practice consider conservative care first? Tragically, some caregivers have complained of having to choose between only two options: costly reconstructive surgery or euthanasia. These caregivers are browbeaten into believing that if they refuse surgery, their dogs will without question suffer painful debilitation from arthritis.8 Is there not a kinder, gentler way? Different Viewpoints …
Managing Hyperthyroidism With Food? Check ComplianceApril 3, 2012 The team at VCA West Los Angeles Animal Hospital was puzzled. Veterinarians had recently begun managing feline hyperthyroidism with nutrition, using a pet food formally launched in October 2011, Hill’s Prescription Diet y/d Feline Thyroid Health. The food limits dietary iodine intake, and the staff was finding that in the majority of cats, thyroid levels returned to normal within three weeks of transitioning to the food. But one patient’s thyroid levels had barely budged—even though the owner insisted the cat had been fed only the recommended food. So team members started probing, says David Bruyette, DVM, Dipl. ACVIM, medical director at the hospital. Was the cat getting treats? Never. Did it sneak bites from other food bowls? Not that the owner knew. Finally, a new fact emerged: The owner had been out of town for 10 days. And it turned out that when the affected cat’s food bowl ran empty, the owner’s husband had simply re-filled it with the same food that the other cats in the household ate, Bruyette says. Bingo. “This food is so good at limiting iodine that if the (cat’s condition) is not improving, there’s an incredibly high chance …
Hill’s Updates Guidelines For Y/d FelineApril 3, 2012 After the launch of its Prescription Diet y/d Feline Thyroid Health pet food last year, Hill’s Pet Nutrition Inc. of Topeka, Kan., has released an updated set of guidelines and algorithms to assist veterinary care providers who are managing hyperthyroid patients with the food. Hyperthyroidism is one of the most common diseases in middle-aged and older cats. Resulting from too-high levels of thyroid hormone (T4) and increased metabolism, the illness can cause a range of clinical findings, from hypertension to ravenous appetite, weight loss and excessive urination. Some cats also have concurrent kidney disease. Traditional treatment options have included radioactive iodine, the medication methimazole to control levels of thyroid hormone, or a thyroidectomy. A decade in the making, Prescription Diet y/d Feline gives veterinarians a new management tool—and so far, says David Bruyette, DVM, Dipl. ACVIM, medical director of VCA West Los Angeles Animal Hospital, it has been working. Since June, Dr. Bruyette and his veterinary health care team have been using the therapeutic cat food to manage newly diagnosed feline hyperthyroid patients and those previously diagnosed that are transitioning from anti-thyroid medication. “What we’ve seen …
FHS May Have Underlying Schizophrenic LinkApril 3, 2012 Feline hyperesthesia syndrome (FHS) is an enigmatic and controversial behavioral and medical condition that most often affects Oriental cat breeds. I saw my first case many years ago in a Siamese cat that displayed the three cardinal signs: excessive skin rippling or twitching (hence the alternative designation “rolling skin disease”), bouts of manic self-grooming, often initiated by stroking the cat along its back (”hyperesthesia”), and widely dilated pupils during bouts of the behavior. The cat had just bitten one of our students, who was trying to restrain him, sending the student to the hospital for intravenous antibiotic treatment. Mercurial aggression, while being restrained, is another feature of FHS in some cats. Other odd behaviors associated with the syndrome include periods of freezing in position while staring vacuously into space, sudden bouts of running away from what appears to be some unseen enemy and apparent hallucinations (visually following things that aren’t there). Learning More In the early days, feline hyperesthesia syndrome was described as a compulsive disorder or stereotypy, but over time I became skeptical of the label to the point where I now consider it incorrect. The first seeds of doubt regarding the compulsive disorder …
Fabulous Feline Fling!March 26, 2012 Close your eyes, and imagine this…well, you can’t read this if your eyes are closed, so have someone else read it to you with your eyes closed…but not if that person is a prankster, because something bad might happen to you while you’re closing your eyes…so use your best judgment. So where were we? Ah yes, telling you what to imagine. I would have loved to get photos for you, and I did get a digital recording, but I’m not so sure they want this running on VPN’s website! It was a few mornings ago. I walk into the kitty palace, the room in which my four cats nap and eat, and the first thing I notice when I open the door is green plant material on the floor. Now we have bunnies, too, so my first thought is hay. But no, I open the door a little more and find the large plastic sack that used to hold all of their catnip, but now most of it is spread out on the floor! I open the door a little further, and see plastic trash bags askew in the room. Hmm, now they are usually stored …
The Case Of The ‘Tummy Tuck’ I Just Couldn’t Get PastMarch 21, 2012 If I hadn’t seen it for myself, I wouldn’t have believed it. A pre-vet student who works for me finally wore me down and convinced me to Google it. That’s when I settled in with my morning coffee to watch a 30-minute video on the merits and how-tos of “tummy tucking” for cats. Tummy-tucking? Seriously? Apparently. And it was awful (as you might have expected it would be). In this case, undertaken in a mobile surgical unit on what appeared to be a middle-aged domesticated shorthair female with an average-sized “belly pooch,” the cat was subjected to a 30-minute procedure dedicated to removing as much subcutaneous fat as possible. Horrible. More so when you consider that one of the major complications with liposuction (done in humans with “lipo-wands” designed for the task) is the potential destruction of blood supply to the overlying skin and, therefore, full-thickness skin necrosis. This complication is rare when the procedure is performed correctly, seeing these wands are specifically designed to leave major vessels intact. But in the cat and dog (distinct from humans) the blood supply to the overlying skin is even more tenuous. While humans have multiple musculocutaneous vessels scattered …
