Unmasking Pet Cancer: The Surprising Truth About Genetics, Toxins and Hormone Trade-offs

Unmasking Pet Cancer: The Surprising Truth About Genetics, Toxins and Hormone Trade-offs

UNMASKING PET CANCER: THE SURPRISING TRUTH ABOUT GENETICS, TOXINS AND HORMONE TRADE-OFFS Hosts Dr. Marty Greer and Laura Reeves discuss the environmental, genetic and hormonal factors of pet cancer to help owners make informed health decisions for their dogs and cats. Key Takeaways * Environmental Factors:Pesticide drift, groundwater chemicals and secondhand smoke are notable hazards. Cats are particularly vulnerable to oral squamous cell carcinoma from grooming smoke particles off their coats. Additionally, a high parathyroid cancer rate is observed in dogs near Fox Valley paper mills in Wisconsin. * Spay/Neuter Hormonal Trade-Offs:Early spaying or neutering increases the risk of lymphoma, hemangiosarcoma, osteosarcoma and mast cell tumors. While spaying before age two protects against mammary cancer, these other cancers are far more common and deadly. Ovaries and testicles produce protective hormones, making ovary-sparing spays and vasectomies valuable alternatives. * Genetics and Breed Risks:Many cancers have strong genetic links, such as lymphoma in Golden Retrievers, hemangiosarcoma in Spinoni, and transitional cell carcinoma in Scotties and Westies. However, after 25 years of research, veterinary geneticists still have not identified specific DNA markers for these common cancers, making complete screening impossible. * Supporting Research:Pet owners can support cancer studies and clinical trials through organizations like the AKC Canine Health Foundation, Morris Animal Foundation and the Pink Paw Fund.

83 — Dog Seasonal Allergies: Apoquel, Cytopoint, Zenrelia & New Numelvi Meds Explained! 🐾

DOG SEASONAL ALLERGIES: APOQUEL, CYTOPOINT, ZENRELIA & NEW NUMELVI MEDS EXPLAINED! 🐾 Dr. Marty Greer and Laura Reeves move past food allergies to dive deep into the itchy world of seasonal pet allergies. From Marty’s hectic week and scenic family getaway to South Dakota to the latest medical breakthroughs, this episode is packed with essential advice to keep your pets comfortable. Key Episode Takeaways * Understanding "Phenology": Nature’s calendar (like tracking the first robin or mosquito of the year) is incredibly consistent. If you track when your pet’s allergies flare up each year, you can start their medicationsone week earlyto stay ahead of the scratching. * The Allergy Treatment Toolkit: * Cytopoint: A targeted, monoclonal antibody injection that blocks the allergic reaction for 3 to 5 weeks. * Apoquel: The original JAK inhibitor, now available in a hypoallergenic chewable form. * Zenrelia: A newer option that carries a strictFDA black box warning—never vaccinate your dog within 30 daysof being on this medication. * Numelvi: The newest second-generation JAK inhibitor on the block. It works in as little as 45 minutes, costs slightly less, and features a highly entertaining"Resting Itch Face"ad campaign starring a crinkly-faced French Bulldog. * Is Prednisone Still Good?: Yes! While newer medications are great for smaller dogs, cheap and classic prednisone is still an effective anti-inflammatory choice for larger dogs or the very end of the allergy season. However, Marty warns that long-acting steroid injections are highly dangerous and can lead to diabetes or Addison's disease. * At-Home Environmental Hacks: Bathing your allergic pet as often as once a week is a safe way to physically wash away contact pollens. Also, be aware that the cozy "fall smell" of raked leaves is actually mold, which can trigger allergic dogs right up until a full snow cover blankets the ground. * A Warning for Cat Owners: Cats rarely experience seasonal allergies. If your cat is chewing or licking its paws, it could actually point to liver problems that require blood work and a liver ultrasound. * Behind the Scenes: Marty breaks down a hilarious "color-matching" marketing trick in TV drug ads and shares a story about spotting a massive "Skin Vet" sign painted on a rooftop in New Zealand.

82 — Pet Allergies & Prevention: Treating Contact Allergies, Bug Bites and Vaccine Reactions

PET ALLERGIES & PREVENTION: TREATING CONTACT ALLERGIES, BUG BITES AND VACCINE REACTIONS Marty and Laura break down how to identify and manage contact allergies, insect bites and vaccine reactions in pets, while sharing why choosing an individualized veterinary care plan is vital for your pet's long-term health. This deep dive shifts focus from food allergies, tackling the lesser-known triggers of pet discomfort -- ranging from contact allergies on a pet’s belly to dangerous spider bites and sudden vaccine reactions. Marty shares crucial safety tips on using over-the-counter medications like Benadryl, demystifies oral vs. topical pest preventatives and closes with a passionate look at why pet owners must advocate for individualized veterinary medicine over "cookie-cutter" clinic protocols. 1. Spotting and Managing Contact Allergies * Where They Appear:Unlike food or environmental allergies, contact allergies almost always present exclusively on the underside of a pet, typically their bellies, feet, groin/scrotum or mammary glands. * Common Triggers:Household items like new wool or knitted blankets, carpet powder and color/scent-filled laundry detergents are frequent culprits. * Practical Solutions:Wash pet bedding in dye- and scent-free "free" detergents. If a dog is sensitive to couch fabrics or sprays, cover their favorite spot with a clean white sheet washed in safe detergent. * Breed Sensitivities:White-coated dogs (such as West Highland White Terriers, Dalmatians and Setters) often have more sensitive skin than darker-colored dogs. 2. Spicy Bites & Spider Bites: Emergency Care at Home * Dogs vs. Cats:Dogs are highly susceptible to severe reactions from bee stings (including facial and airway swelling), whereas cats rarely have these issues. * The Danger of Spiders:Marty notes that she treats far more severe reactions from spider bites (such as brown recluse or black widows) than bee stings. These bites can cause aggressive, necrotic skin lesions that are difficult to diagnose because pets can’t tell us what bit them. * Using Benadryl Safely:Benadryl is safe to use at home for acute insect-bite facial swelling. * Dosage:The proper dosage is2 to 4 milligrams per kilogram(calculated by dividing your dog's weight in pounds by two, and then multiplying by two to four). * Safety Warning:Only use straight Benadryl. Never administer products mixed with Tylenol, other pain medications, or liquid formulations containingxylitol(which is toxic to dogs). * Flea Allergies: Sensitive pets can experience severe flea-bite dermatitis from just one single flea bite a week. 3. Oral vs. Topical Pest Preventatives * Oral Preventatives:Modern oral medications (like Bravecto, Credelio, NexGard, and Simparica) offer fantastic protection against fleas and ticks, but theydo notrepel mosquitoes or biting flies. * Topical Preventatives:High-quality prescription topicals (such as Vectra 3D) provide excellent repellency, acting like a "shield" that keeps biting bugs off your pet entirely. * The Seizure Risk:Oral flea and tick medications of this class can lower the seizure threshold in seizure-prone dogs. Injectable long-lasting preventatives (like the one-year Bravecto Quantum) are convenient but should only be started once a dog has safely tolerated the oral class first. * Natural Products Myth:Marty cautions that natural repellents (like Wondercide or home remedies like Guinness Beer) are not reliably effective at preventing tick-borne illnesses like Lyme disease.

81 — Pet Food Allergies in Dogs and Cats: Myths, Symptoms and Elimination Diets

PET FOOD ALLERGIES IN DOGS AND CATS: MYTHS, SYMPTOMS AND ELIMINATION DIETS Dr. Marty Greer and Laura debunk common pet food myths about corn and wheat while sharing step-by-step veterinary strategies for diagnosing genuine food allergies and sensitivities in dogs and cats. * Symptoms & Presentation: Unlike human food allergies, pet food allergies primarily manifest as skin issues—such as intense scratching, chewing, biting and ear infections—rather than digestive upset. Only about 20% of allergic dogs show signs of vomiting and diarrhea. In cats, symptoms are heavily concentrated as intense scratching around the head and neck. * Debunking the Corn Myth: Despite the popularity of "no corn, wheat, or soy" marketing, the most common food allergens for dogs are actually beef, chicken, lamb, wheat and dairy. For cats, the top allergens are beef, chicken and fish. * The Inefficacy of Retail Allergy Tests: Blood, saliva and skin test kits sold online are unreliable. Veterinary dermatologists do not recommend them. * How to Run a Strict Food Trial: The only reliable diagnostic method is a provocative food trial lasting up to 12 weeks. This involves feeding the pet either a prescription hydrolyzed protein diet (where proteins are broken down so small that the immune system doesn't detect them) or a carefully prepared homemade diet. During the trial, the pet must consumeonlythis food and water—no treats, rawhides or table scraps. * Systematically Identifying Allergens: After a successful trial, owners can systematically introduce one ingredient back into the diet per week (such as beef, chicken or wheat) and track reactions on a calendar to identify specific triggers. * Allergies vs. Sensitivities vs. Food Poisoning: Allergies prompt immune-mediated skin issues, whereas food sensitivities present as digestive discomfort, chronic diarrhea or picky eating. True food poisoning comes from spoiled foods, dead animals or unique toxins—such as a pink mold on soft cheeses (like cream cheese) that can cause seizures in dogs. * Predisposed Breeds: Food allergies are most frequently seen in Labradors, German Shepherds and West Highland White Terriers for dogs, and in Oriental breeds like Siamese, Persian and Burmese for cats. * Helpful Resources: * Homemade Diets  [https://www.wiley.com/en-us/shop/general-introductory-veterinary-medicine/home-prepared-dog-and-cat-diets-2nd-edition-p-9781119949510] * Balanceit [https://balance.it/]
