A Safer Way to Handle High-FAS Dogs When a Muzzle Isn’t an Option

Some dogs come into the exam room with high FAS (Fear, Anxiety, Stress) and simply cannot tolerate a traditional muzzle. The more you try, the more escalated they become—and suddenly your fingers are way too close to the danger zone.

Here’s a simple, safer trick that can protect both the patient and your hands.

Use an Oxygen Mask as a Safety Barrier

Instead of struggling to place a muzzle, grab an oxygen mask (O2 mask) that fits the dog’s muzzle. You can use it with or without the black rubber diaphragm. *** Watch their eyes ***

How to use it:

1. Quickly slide the oxygen mask over the dog’s nose.

2. The hard plastic serves as a protective barrier for your hands.

3. Once the mask is on, you can apply a muzzle around the outside of the mask to secure it.

4. Hold in place—the mask is heavier than a standard muzzle.

This method reduces the dog’s stress, keeps your hands safer, and still allows you to move forward with necessary care.

Bonus: Perfect for CHF & Respiratory Patients

This trick is extra helpful for CHF (congestive heart failure) patients, cyanotic patients, or any dog who needs supplemental oxygen.

Once the mask is on, simply connect it to your oxygen line for immediate support. You get safety + oxygen delivery all in one step.
