79 -- Canine Heart Disease Guide: Managing Mitral Valve Disease and DCM in Dogs

CANINE HEART DISEASE GUIDE: MANAGING MITRAL VALVE DISEASE AND DCM IN DOGS Marty and Laura dive into canine cardiac health, breaking down the causes, symptoms and life-extending treatments for the two most common acquired heart diseases in dogs: mitral valve disease in small breeds and dilated cardiomyopathy (DCM) in large breeds. * Mitral Valve Disease (Small Breed Dogs): * Who it affects:Small breeds like Shih Tzus, Schnauzers and Cavalier King Charles Spaniels. * The Cause:Genetic factors lead to "knobby" protrusions on the left-side mitral valve, preventing a proper seal and causing blood to leak backward into the left atrium. * Proactive Monitoring:Owners should count their dog’s resting respiratory rate monthly while they are horizontally asleep. Normal is 26 to 32 breaths per minute; rates climbing past 38 to 40 require veterinary attention. * Symptoms:Look out for reduced exercise tolerance, weight loss (cardiac cachexia), and a persistent cough (often caused by an enlarged heart pressing on the trachea). * Prevention & Care:Excellent dental health and routine brushing can prevent bacteria from latching onto damaged heart valves. * Dilated Cardiomyopathy / DCM (Large Breed Dogs): * Who it affects:Primarily large breeds like Great Danes, Dobermans, Boxers and Newfoundlands, with rare exceptions in small terriers. * The Cause:The heart muscle becomes flabby and weak, impairing its ability to contract. DCM can stem from genetic factors, chemotherapy drugs or nutritional deficiencies (taurine and L-carnitine) linked to grain-free or legume-rich diets. * Symptoms & Risks:Unlike small dogs, large dogs with DCM are highly prone to dangerous arrhythmias (irregular heartbeats), fainting and sudden acute heart failure. * Diagnosis and Modern Treatments: * Diagnosis is Accessible:Any primary care veterinarian can diagnose an enlarged heart using a standard chest X-ray and a Vertebral Heart Score (VHS) to normalize heart size against the spine. * Improved Lifespans:While dogs diagnosed with heart disease historically survived only six months, modern medications can give them two to three more high-quality years. * Primary Medications:Treatment frequently relies onPimobendan(a veterinary-only drug that strengthens heart contractions), ACE inhibitors (enalapril or benazepril), and diuretics like furosemide (Lasix) or spironolactone. * Cardiac Emergencies:Tears in the chordae tendineae (fibers holding the valve) can trigger sudden, severe failure. Advanced hospital care can include oxygen, sildenafil (Viagra) for pulmonary hypertension, nitroglycerin, and amlodipine. Note that canine CPR is rarely successful in chronic cardiac arrest, so owners should not harbor guilt if they cannot revive an arresting pet.

78 -- Canine Eye Health: Navigating Cataracts, Glaucoma and the Third Eyelid

CANINE EYE HEALTH: NAVIGATING CATARACTS, GLAUCOMA AND THE THIRD EYELID In this final installment of our eye anatomy series, Marty and Laura break down the critical differences between common canine eye conditions, exploring the causes and treatments for cataracts, glaucoma, uveitis and issues affecting the third eyelid. Episode Highlights: Cataracts vs. Nuclear Sclerosis: We explain how rapid-onset cataracts are frequently linked to diabetes in dogs, while the harmless, cloudy-looking eyes seen in older pets are a natural aging change called nuclear sclerosis that does not lead to blindness. The Emergency of Glaucoma: Learn why high intraocular pressure is a major emergency in dogs. Unlike in humans, a dog's eye pressure can shoot up overnight, potentially causing permanent blindness within 24 hours if not treated immediately. Symptoms to watch for include a bulging eye, a "steamy" cornea, and a red sclera. Uncovering Uveitis: We discuss uveitis, a condition characterized by low eye pressure and inflammation. Because "the eyes are the window to the brain," uveitis often signals a deeper underlying disease, such as a tick-borne illness or an infection, requiring a thorough veterinary workup. Third Eyelid Troubles: Discover the mysteries of the canine third eyelid. We demystify "cherry eye" (a prolapsed gland that looks scary but isn't painful) and discuss follicular conjunctivitis, a common and easily treatable inflammation caused by environmental irritants like pollen and dust.

77 -- Unlocking Canine Retina Health: Blindness, Detachments and Genetics in Dogs

UNLOCKING CANINE RETINA HEALTH: BLINDNESS, DETACHMENTS AND GENETICS IN DOGS Join Marty and Laura as they dive into the complex world of the canine retina, exploring common eye diseases, the dangers of retinal detachment and essential genetic health screenings. Our hosts focus on the canine retina, an essential part of the back of the eye that acts like the "film" in a camera to interpret light, images and motion. Because the retina is a highly complex structure, diagnosing retinal issues often requires the specialized equipment and training of a veterinary ophthalmologist. Key Topics Discussed: * Retinal Detachment:This is a severe condition that usually results in blindness. In dogs, it can be triggered by trauma, tumors, immune-mediated diseases, uveitis, or high blood pressure linked to kidney failure or hyperthyroidism. While humans can often have their retinas reattached via laser, it is incredibly difficult and rare to successfully reattach a dog's retina. * Hidden Blindness in Pets:Dogs and cats are incredibly skilled at hiding their vision loss by memorizing their home's layout. Owners may not realize their pet is going blind until they rearrange the furniture or move to a new house. * SARD (Sudden Acquired Retinal Degeneration):A rare, irreversible condition of unknown cause where a dog suddenly goes blind. * The Dangers of Merle-to-Merle Breeding:Breeding two dogs with the Merle gene (such as Aussies or Collies) can produce puppies with severe visual and hearing impairments. It is crucial to DNA test for "cryptic Merles" to avoid accidentally crossing two Merle dogs. * The "Hybrid Vigor" Myth:Mixing two breeds, such as a Bernese Mountain Dog and a Poodle to make a Bernadoodle, does not magically cure or filter out bad genetic traits. Sometimes, this combination actually doubles up on genetic issues. * Health Testing & Preventive Care:Responsible breeders and owners should utilize both DNA tests for conditions like Progressive Retinal Atrophy (PRA) and physical exams by a veterinary ophthalmologist. Breeders can visit the Canine Health Information Center (CHIC) website to discover which specific eye diseases to test for based on their dog's breed. * Medication Toxicities:Giving a dog a massive, accidental mega-dose of ivermectin—such as using farm store variants instead of proper heartworm preventatives—can lead to temporary blindness.

76 — Dog Eyelid Health Guide: Entropion, Dry Eye and Puppy Eye Emergencies

DOG EYELID HEALTH GUIDE: ENTROPION, DRY EYE AND PUPPY EYE EMERGENCIES Welcome back to the Marty and Laura Show! In this episode, we are continuing our deep dive into the fascinating world of canine eye care. You might think an eyelid is simple, but as Marty explains, there are six main categories of eyelid issues to watch out for: swellings, tumors, infections, allergies, immune-mediated diseases, and conformation. Key Topics in This Episode: * Entropion vs. Ectropion:Learn the crucial difference betweenentropion(where the eyelid painfully rolls inward and scratches the eye) andectropion(the loose, droopy eyelids commonly seen in Bassets, Saint Bernards and Clumber Spaniels). If a young puppy suffers from entropion,getting their eyelids temporarily "tacked" is vital to break the cycle of squinting and prevent permanent corneal damage. * Breed Conformation:We discuss why sled dogs have almond-shaped eyes to protect against harsh snow, while brachycephalic breeds have large, round eyes for a more infant-like appearance. * The Secret of Tear Ducts:Did you know that tears actually drain into the nose? We explain how vets easily test for blocked tear ducts using glowing fluorescein dye. * Dry Eye & The Tear Film:A dog's tear film consists of a water layer, a mucus layer, and an oil layer. We issue a major warning: if your dog develops "cherry eye,"never allow the third eyelid gland to be surgically removed, as it produces the crucial watery layer of the tears and removing it will cause permanent dry eye later in life. * Eyelid Tumors and Mites:Discover why most eyelid margin tumors in older dogs are benign, whereas cats face a higher risk of cancer. Plus, we share a mind-blowing fact aboutDemodex mitesliving in the eyelid margins of dogs—and humans! * Neonatal Ophthalmia:A critical alert for dog breeders. If an infection develops behind a young puppy's closed eyelids before they naturally open,it is a genuine medical emergency. The eyelids must be opened immediately to prevent the puppy from going completely blind. At-Home Care Tips: If your dog has a mild garden-variety eye discharge, you can try washing it with a little baby shampoo, using artificial tears, and applying a warm compress before your vet appointment. However, always get a proper diagnosis from a veterinarian before administering antibiotics or steroids.

75 — Canine Corneal Health: A Guide to Dog Eye Problems, Ulcers and Care

Join Marty and Laura as they "scratch the surface" of dog eye health, breaking down everything from painful corneal ulcers to the right way to safely wrestle your pup for their eye drops! We might be a little punch-drunk from a busy weekend of seminaring, but we are absolutely thrilled to kick off our new mini-series all about your dog's eyeballs! Today, we are keeping things focused on the cornea—that beautifully clear window at the very front of the eye. In this episode, we dive into: * Eye Anatomy 101:Why the cornea needs to stay perfectly clear and why sudden cloudiness, redness or brown pigment means you need to get to the vet yesterday. * Pigmentary Keratitis (PK):Why flat-faced cuties with protruding eyes (we're looking at you, Pugs and Frenchies!) are so prone to this dark pigmentation and how to manage it. * Corneal Ulcers:The super painful reality of grass seeds, bush scratches and even car airbag injuries (PSA: Please keep your dog out of the front seat!). * The Golden Rule of Eye Meds:Why you mustneveruse a leftover steroid eye drop on your dog without a vet checking for an ulcer first. * Vet Tests Demystified:What to expect at the clinic, including why that agonizingly long 60-second Schirmer tear test always has to be the very first step. * Pro-Tips for Meds:Marty’s expert advice for getting eye drops into a squirmy dog—hint: back them into a corner and straddle them. * Doggy Contact Lenses?Yes, you heard that right! Learn how vets use human soft contact lenses as a "bandage" to save your dog's vision while an ulcer heals. A quick reminder: If your dog's eye is slammed shut, watering or looks "steamy" (like a bathroom mirror after a hot shower), treat it as an emergency and get to a vet or ophthalmologist immediately!
