⚠️ DO YOU KNOW THE SIGNS OF A SNAKE BITE? ⚠️

Rattlesnakes are active across Central Texas this time of year — and curious dogs are often the first to investigate.

Knowing the signs of a snake bite could save your pet’s life.

Watch for these symptoms:

🚨 Sudden swelling around the face, leg, or body
🚨 Intense pain or whining
🚨 Lethargy or weakness
🚨 Puncture wounds
🚨 Rapid swelling or bruising

If your dog shows any of these signs after being outside, seek veterinary care immediately.

The best protection is prevention.

🐍 March Special:
10% OFF Rattlesnake Vaccinations

Help reduce the severity of a bite before it becomes an emergency.

🌅 DAY 4 – SPRING IS HERE 🌸🐾

The days are getting longer.
The sun feels warmer.
Wildflowers are blooming across Texas. 🌼

Spring is one of the most beautiful times of year to be outside with your dog — hikes, ranch days, lake trips, backyard playtime.

But spring also means something else…

🐍 Rattlesnakes are becoming active.

As temperatures rise, snakes come out of brumation and begin moving through the same fields, trails, and neighborhoods our dogs love to explore.

The good news?
You can be prepared.

🚨🌿 Pet Poison Prevention – Day 5 🌿🚨

Outdoor plants can be just as dangerous as household chemicals.

Many common yard and garden plants are toxic to pets, including:

🌺 Azaleas
🌼 Lilies (extremely toxic to cats!)
🌱 Sago Palm
🌷 Tulips
🍄 Wild mushrooms

Even small amounts can cause serious illness.

Before planting this spring, check that your landscaping is pet-safe. A little prevention now can save an emergency later.

If your pet chews on a plant and seems unwell, call us immediately.

🚨 EMERGENCY ROOM REALITY CHECK 🚨

One bite.
That’s all it takes.

Every spring in Central Texas, we see dogs rushed into the ER after a rattlesnake encounter. Swelling. Pain. Panic. Expensive emergency treatment.

And in those moments, every pet owner says the same thing:

“I wish I had done this sooner.”

🐍 Rattlesnakes are active.
🌡️ Warmer weather means higher risk.
🐶 Curious dogs don’t know the danger.

Don’t wait until you’re sitting in an emergency room praying for a different outcome.

🚨🧴 Pet Poison Prevention – Day 4 🧴🚨

Did you know many poison emergencies happen inside the kitchen and bathroom?

Common indoor dangers include:

🧼 Cleaning products
💊 Over-the-counter medications
🍇 Grapes & raisins
🧄 Onions & garlic
🧃 Sugar-free products with xylitol

Curious pets explore with their noses — and sometimes their mouths.

Keep all medications and chemicals stored securely and out of reach.

If you think your pet ingested something toxic, call us immediately.

🚨🌿 Pet Poison Prevention – Day 3 🌿🚨

Spring yard season is here — but some lawn products can be dangerous for pets.

Watch out for:

🌱 Fertilizers
🧪 Herbicides
🐭 Rodent bait
🍫 Cocoa mulch

Even walking through treated grass and licking paws later can cause problems.

Before treating your yard, make sure products are labeled pet-safe — and always follow directions carefully.

If you suspect exposure, call us immediately.
