On a Tuesday at 4:11 a.m., in a fenced backyard in a quiet residential street outside Albuquerque, New Mexico, a six-pound chihuahua named Pico stood at the gate at the back of the yard and barked at something the household could not yet see. The household was the Castillo family: two adults, a teenage daughter, and the dog. The dog had been let out for a quick pre-dawn potty break and had not, on the available evidence, returned in the expected sixty seconds.

favoriteMrs. Castillo, who had let the dog out, looked through the kitchen window. She saw, at first, only Pico at the back gate. Then she saw, on the other side of the gate, the eyes; a coyote, by her later description, of medium size, standing at the property line, pacing.
This is the story of the next eleven minutes, the response that worked, and the small adjustments to property and routine that the family has made since.
The eleven minutes
article_in_feed
A handpicked find for your tiny companion.
Mrs. Castillo did not, to her credit, run into the yard. She woke her husband. They watched from the kitchen window for about ninety seconds, assessing. Pico held the gate. The coyote held the property line. Neither moved.
At 4:13 a.m. Mr. Castillo turned on the porch light and the back-deck floodlight, then opened the kitchen door and called Pico in a calm tone. Pico did not break eye contact with the coyote and did not, immediately, come. Mr. Castillo stepped onto the deck (not into the yard) and clapped his hands three times, slowly, then called again. The coyote, on the second clap, took a step back. Pico did not move.
At 4:15 a.m. Mr. Castillo banged a metal mixing bowl with a wooden spoon, which is the noisemaker the family keeps near the back door for exactly this reason. The coyote retreated to the alley. Pico, after a beat, walked, slowly and with the bearing of a small dog who had decided the perimeter was now stable, back to the deck. The household, all four of them, were inside by 4:17 a.m.
Nobody, in the eleven minutes, had been bitten or injured. The fence had not been compromised. The coyote had not, as far as anyone could see, breached the property line.

Why the response worked, plainly
I called a wildlife biologist, a Dr. Karen Beltran with the New Mexico Department of Game and Fish, the next week to ask her what the family had done right. Her summary was short.
"They did not run into the yard. They used noise and light, not bodies. They gave the coyote a clear escape route. The dog, in this case, did the right thing for a small dog, which is to hold a defensive position at a barrier and not, on its own, advance."
Coyote-on-small-dog encounters, Dr. Beltran said, are most often catastrophic when the dog is off-leash beyond the property line, when the household runs out into the yard and increases the chaos, or when the dog advances rather than holds. The Castillo response, by accident or by reading, did none of these.
The California Department of Fish and Wildlife coyote-coexistence guidance, which I have read several times across this beat, is the document I would point any reader in a high-coyote region to. The principles are the same across western states.
The changes the family made
The Castillos, after the incident, made a small set of property and routine adjustments:
- No off-leash time after dark or before dawn. Pico now goes out on a 15-foot leash for early-morning and late-evening breaks, even in the fenced yard.
- Motion-activated yard lighting. Two LED units at the property line, $35 each at the local hardware store, that come on when something the size of a coyote crosses the perimeter.
- The mixing bowl and spoon stay by the back door. Mrs. Castillo wrote a small note on the inside of the door that says "noise first."
- Coyote roller along the top of the back fence. A roller bar that prevents a coyote from getting purchase on the top of a six-foot fence; commercially available and effective in the published wildlife-management literature.
- A check of the fence line. A monthly walk-through to look for new digging at the base.
None of these are dramatic. All of them are, in aggregate, a different perimeter.
What this asks of readers in high-coyote regions
A short list, since several of the readers of this site live in regions where this is a real concern.
- Know your coyote pattern. Coyotes are most active at dawn and dusk. Plan small-dog outdoor time around the gap, not through it.
- Never let a small dog off-leash beyond the property line. The risk math is not symmetric.
- Use noise and light, not bodies. Air horns, clapping, banging, motion-activated lighting. The coyote is, on the available evidence, more responsive to noise than to confrontation.
- Property-line maintenance. Fence height, fence integrity, and the absence of attractants (open trash, pet food left outside) all matter. The bond between a small dog and a household includes the household's quiet stewardship of the perimeter.
- Have a written plan. The 4 a.m. version of you is not the same person as the noon version. A small note on the inside of the back door is more useful than you would think.
Where Pico is now
Pico is, as of this writing, asleep on a small fleece bed at the foot of the Castillos' bed. The motion-activated lights on the back fence have triggered four times in the eight weeks since the incident, three of which were a neighborhood cat. The mixing bowl is still by the back door. A separate coyote-and-chihuahua story I wrote two years ago ended with a similar paragraph; the math is the same in both households.
If you live in a region where coyotes are present and you have not yet thought through the perimeter, the small steps above are most of the work. The hardware-store visit is forty-five minutes; the fence walk is fifteen; the mixing bowl is in your kitchen already. The dog, the perimeter, and the noise. That is the whole system.
