Moon Crest understands that things happen and that life can change.
When things change and if you can no longer keep your Moon Crest puppy, Moon Crest Jack Russell Terriers will be happy to take your pup back no matter what age they are.
We will never question why, think poorly of you or judge your decision. The fact you are doing right by the pup and having them come back to where they were born is the next best thing.
Sadly, this handsome guy, was just surrendered back to us.
His name is Reggie.
Reggie will be staying with us for evaluation before he will be offered available.

Tonight I ended up trying to help a friend whose puppy ate a kid's vitamin containing xylitol. Simple accident: kid dropped vitamin, puppy scarfed it down. (Note: this household is knowledgeable and is xylitol free, but a relative bought the vitamins, unaware of the risk to the dogs.)

The puppy only ate *one* vitamin. Which turned out to contain 1500 mg of xylitol.

100 mg/kg is the threshold for hypoglycemia which can be fatal. At 500 mg/kg, hepatic necrosis occurs -- destruction of liver tissue.

So just ONE chewable vitamin ended up creating a serious problem for a 30 pound pup (which is not quite 14 kg).

The emergency vet induced vomiting. Thankfully, the puppy had had a meal and so there was food in her stomach. In the vomit was the orange tablet, identifiable though dissolved.

Quick thinking on the owner's part (including grabbing the bottle of vitamins) and fortunately a nearby 24/7 emergency vet hospital meant that this pup received prompt treatment, and should make a full recovery.

Check your medications, vitamins, gum, candy, toothpaste, mouthwash, peanut butter and more for xylitol, also known as birch sugar.

This is useful information to have on hand:

ALWAYS contact vet and ASPCA Animal Poison Control center immediately!

As for everyone (the non-vets) recommending the use of hydrogen peroxide, please update your understanding:

Pass this along. I hope you never have to use it.

Being “tick smart” can make all the difference when it comes to protecting your pet from tick-borne diseases.

Ticks tend to hide in warm, hard-to-see areas on your pet’s body, so regular checks are key, especially after walks, hikes, or time outdoors.

Common places to find ticks on pets:
✔ Around the ears and ear folds
✔ Under the collar
✔ Between toes and paw pads
✔ Around the eyes and eyelids
✔ Under the tail and around the groin
✔ In armpits (front legs)

Safe tick removal tips:
✔ Use fine-tipped tweezers or a tick removal tool
✔ Grasp the tick as close to the skin as possible
✔ Pull upward with steady, even pressure (don’t twist)
✔ Avoid crushing or squeezing the tick
✔ Clean the area with antiseptic after removal
✔ Wash your hands thoroughly

Never use methods like burning, petroleum jelly, or essential oils, these can actually increase the risk of disease transmission.

Ticks can spread illnesses like Lyme disease and ehrlichiosis, so prevention and early removal are critical.

📍 If you’re unsure how to remove a tick or notice redness, swelling, or lethargy after a bite, contact your veterinarian right away.

As we celebrate 50 years of the Jack Russell Terrier Club of America, here’s something you might not know…

Go-To-Ground tests a terrier’s natural hunting instinct by following a scent through a tunnel system to locate quarry. It reflects the original purpose of the breed in a controlled setting.

This is what 50 years of preserving a working terrier looks like.

Thanks to Rose Rodriguez for the great pictures of Jonathan Morales and their girl Juniper working on her GTG skills!

The Balance Behind a Good Working Terrier

I know this is a topic I keep coming back to, but it is just such an important part of successfully living with any working breed. One of the biggest misunderstandings about working-bred dogs is the idea that exercise alone creates fulfillment.

Physical exercise alone does not always create stability or fulfillment.

Many working and hunting breeds were developed to use both their bodies and their brains for hours at a time. Tracking. Hunting. Retrieving. Problem solving. Searching. Working independently while still handling pressure, structure, and direction from a handler.

That kind of instinct and drive does not disappear simply because the dog now lives in your home.

A walk around the neighborhood may provide physical movement, but for many working dogs, that alone does not meet the mental and instinctual needs they were bred for over generations.

This is why some dogs continue to struggle even after “lots of exercise.”

Not necessarily because they are “bad,” “crazy,” or poorly bred — but because many high-drive dogs also need:
• Engagement
• Structure
• Training
• Problem solving
• Clear expectations
• Purpose
• Appropriate outlets for instinct

A dog bred to use its brain will often create its own job when no direction is provided.

Digging.
Chewing.
Pacing.
Demand barking.
Obsessive behaviors.
Constant motion.

Dogs will naturally look for an outlet when those needs are unmet.

At the same time, good working dogs should also be capable of learning an off-switch.

An off-switch is not simply genetic luck.
It is developed through fulfillment, consistency, structure, and learning how to settle.

A well-bred working dog should be capable of both:
working hard when asked
and relaxing inside your home when its needs are appropriately met.

That balance matters.

Working-bred dogs can absolutely make wonderful companions and family dogs in the right homes. But instinct, drive, intensity, and purpose do not disappear simply because a breed is marketed as “just a pet.”

Generations of genetics still matter.

This is why responsible placement matters so much.

Before choosing a working or hunting breed, it is important to honestly ask:
Can I provide more than basic exercise?
Can I provide engagement, structure, training, and appropriate outlets?
Can I live with the traits this breed was intentionally developed for?

Because instinct and drive are not things that simply disappear with environment alone.

And in the right environment, those same traits people struggle with are often the exact traits that make these dogs exceptional.

The dog pictured is Thistle Ridge Chigger, one of the best examples of balance, instinct, intelligence, and stability I’ve ever owned. She worked in the field, tracked wounded game, raised not only her puppies, but a litter of orphan puppies, traveled everywhere with me, and still had the ability to quietly settle inside the house. She also remains an important part of the maternal foundation behind my program, with many of the traits discussed here still strongly represented through the dam line she helped shape.

Your backyard may feel like a safe haven, but it can hide several potential dangers for your pet.

As pets spend more time outdoors in spring and summer, it’s important to be aware of common hazards that could impact their health.

Watch out for:
✔ Fertilizers and lawn chemicals
✔ Toxic plants like azaleas, lilies, and sago palms
✔ Standing water that can harbor bacteria or parasites
✔ Foxtails and grass awns that can embed in skin
✔ Open gates or fencing gaps

Even small exposures can lead to serious health issues if not addressed quickly.

📍 If your pet shows signs of illness or injury, contact Veterinary Village right away.
