Spring Pet Dangers in East Tennessee: What to Watch For

Spring in East Tennessee is beautiful — warmer temperatures, blooming dogwoods, longer walks, and more time outside with your pets. It also brings a handful of hazards that every Knoxville pet owner should know about before they hit the trail or the backyard.

We've been serving Knoxville pet owners since 1976, and spring is consistently the season when we get the most calls about pets getting into something they shouldn't have. Here's what to watch for this time of year in East Tennessee specifically — because our region has its own set of seasonal risks.

Toxic Spring Plants Common in East Tennessee

East Tennessee's lush spring landscape is one of its best features — and one of its biggest hidden dangers for pets. Many of the plants that bloom across Knoxville yards and hiking trails in March, April, and May are toxic to dogs and cats.

Azaleas and Rhododendrons are everywhere in East Tennessee and are highly toxic to both dogs and cats. Even a small amount of ingested leaves or flowers can cause vomiting, drooling, weakness, and in severe cases, heart problems. These are beautiful plants — and they're in almost every Knoxville neighborhood.

Daffodils and Tulips are common in spring gardens and are toxic to pets, particularly the bulbs. Symptoms of ingestion include vomiting, diarrhea, and lethargy. If you're planting bulbs this spring, keep dogs out of the garden while you work and after planting.

Wild onions and ramps are abundant on East Tennessee trails in early spring. Both are toxic to dogs and cats and can cause a condition called hemolytic anemia — where red blood cells are destroyed — if eaten in sufficient quantity. Ramps in particular grow prolifically in the Smokies and surrounding foothills.

Wisteria blooms spectacularly across Knoxville in April and is toxic to pets. All parts of the plant — seeds, pods, leaves — can cause vomiting and diarrhea.

Cocoa Mulch — A Hidden Spring Hazard

Many Knoxville homeowners lay fresh mulch in their gardens each spring, and cocoa mulch — made from cocoa bean shells — has become popular because of its rich color and pleasant smell. That same smell that attracts you to it also attracts dogs.

Cocoa mulch contains theobromine and caffeine, the same compounds that make chocolate toxic to dogs. Ingestion can cause vomiting, diarrhea, muscle tremors, seizures, and in severe cases, death. If you have dogs, opt for cedar or pine mulch instead and be cautious at neighbors' homes and parks where cocoa mulch may be used.

Fleas and Ticks — East Tennessee's Spring Surge

Flea and tick season in East Tennessee starts earlier than most people expect. By mid-March, when temperatures consistently reach the mid-50s, flea populations begin to reactivate. Ticks — particularly the American dog tick and the black-legged tick (deer tick) — are active even earlier, sometimes in temperatures just above freezing.

East Tennessee's wooded neighborhoods, trail systems, and proximity to the Great Smoky Mountains National Park make this a particularly high-risk region. The Smokies are one of the most tick-dense environments in the eastern United States.

At Agri Feed Pet Supply we carry a full range of flea and tick prevention options — both conventional and natural — so you can choose the approach that's right for your pet and your household.

Conventional options include Advantix and Advantage, two of the most trusted topical treatments available, as well as Seresto collars, which provide up to 8 months of continuous flea and tick protection without monthly application.

Natural options are growing in popularity for pet owners who prefer to avoid chemical-based treatments. We carry Earth Animal and Wondercide — two of the most respected natural brands in the category — available in sprays, collars, and drops. These are plant-based formulas that repel fleas and ticks without synthetic pesticides and are safe to use around children and other pets.

Grooming tools are an essential part of any flea and tick routine regardless of which prevention method you choose. We carry flea combs for detecting and removing fleas from your pet's coat, tick twisters for safe and complete tick removal, and several flea and tick shampoos for bathing as part of your prevention or treatment protocol.

Not sure which approach is right for your pet? Come in and talk to our team. We can walk you through the options based on your pet's size, lifestyle, and how much time they spend outdoors.

Spring Allergies — Yes, Pets Get Them Too

East Tennessee is one of the highest pollen regions in the country. Knoxville regularly appears on lists of the worst cities for seasonal allergies — and what affects you affects your pets too, just differently.

While human allergies typically manifest as sneezing and watery eyes, pet allergies more commonly show up as skin symptoms: excessive scratching, licking paws, rubbing their face, red or inflamed skin, and recurring ear infections. If your pet is suddenly scratching more in spring, seasonal environmental allergies are a likely culprit.

Diet plays an important supporting role here. Pets on high-quality, minimally processed diets with strong omega fatty acid profiles tend to have better skin barrier function and may experience less severe seasonal allergy symptoms. Brands like Farmina N&D, Open Farm, and Carna4 are formulated with this in mind. Come talk to us if you're seeing signs of seasonal allergies in your pet — we can help you evaluate whether a food change might help.

Snakes — A Real Consideration on East Tennessee Trails

East Tennessee is home to two venomous snake species: the timber rattlesnake and the copperhead. Both become active in spring as temperatures warm, and both are commonly encountered on area trails — including popular Knoxville-area greenways and Smoky Mountains hiking paths.

Dogs are naturally curious and are at real risk of snakebite, particularly on the face and legs. Keep dogs on a leash on trails during spring and summer, stay on marked paths, and watch where your dog puts their nose. If your dog is bitten, stay calm, keep them still, and get to a veterinary emergency clinic immediately. Do not attempt to suck out venom or apply a tourniquet.

Lawncare and Garden Chemicals

Spring is when Knoxville yards get their first treatments of the year — fertilizers, herbicides, pesticides, and pre-emergent weed killers. Many of these are toxic to pets, and the risk isn't just from direct ingestion. Dogs that walk across treated lawns and then lick their paws are ingesting trace amounts of whatever was applied.

• Keep pets off treated lawns for at least 24-48 hours after application, or longer if rain hasn't occurred
• Ask neighbors if they've treated their lawn before allowing your dog to walk on it
• Wipe your dog's paws after walks in areas where lawn treatment may have been applied
• Consider organic or pet-safe lawn treatment options for your own yard

A Note on Nutrition and Spring Wellness

We talk a lot about food — it's what we do. But it's worth saying here: a dog or cat on a high-quality diet with strong immune function is genuinely better equipped to handle the seasonal stressors that spring brings. Better skin means a stronger barrier against environmental allergens. Robust gut health supports immune response. Quality omega fatty acids reduce inflammation.

Spring is a great time to reassess what's in your pet's bowl. If you've been thinking about making a change or upgrading their food, come see us. We're always happy to help.
