A fenced yard is supposed to be the one place your dog can pace, sniff around, and mind its own business without trouble. In Three Forks, that sense of security broke down fast when a woman reviewed her home security footage and saw the moment her dog reacted in pain—right there inside the fence line.
Gallatin County Sheriff’s deputies say the neighbor, Denis Dale Christenson, later admitted he fired a pellet gun from his own property and struck the dog from roughly 20 yards away. Details in the original post outline how the camera footage, the injury, and the follow-up veterinary report quickly turned a neighborhood gripe into a felony case.
The camera caught a quick moment that mattered
According to charging documents, the victim called 911 and showed deputies video from a security camera at the front of her home. In the clip, the dog is walking from the front of the fenced yard toward the house when a sound occurs. The dog jolts, looks to the north, and then runs to the south end of the yard.
Deputies observed what they described as a circular puncture wound on the dog’s left flank, oozing blood. That kind of detail matters, because it’s the difference between a vague complaint and a documented injury that lines up with what the camera shows.
A running neighbor feud over barking and the fence line
The woman told deputies this wasn’t the first time she believed Christenson had shot her dog. She also described a history of him complaining about the dog, and said he would antagonize the dog through the fence dividing the properties, then complain when the dog barked.
Anyone who’s lived in tight rural subdivisions—or even just on small-acreage ground—knows how quickly “your dog barks” turns into a bitter, personal issue. But the fence is the boundary for a reason. If a dog is contained in its own yard, the options for dealing with noise and irritation are a whole lot different than taking shots through a property line.
Deputies say the neighbor admitted he shot the dog
Deputies contacted Christenson by phone, and he agreed to speak with them in his front yard. The affidavit states that he said the dog had been barking in the morning and again right before he left to get groceries.
When deputies asked what happened after that round of barking, he reportedly became visibly angry and admitted he shot the dog. Christenson told deputies he used a pellet gun, and investigators seized the gun along with a pellet container that still had pellets in it.
Why a pellet gun isn’t “just a pellet gun”
Some folks hear “pellet gun” and think it’s no big deal—like it’s automatically harmless. Out in the real world, that’s not how it works. Even without getting into brand names or velocities, a pellet gun can absolutely injure or kill an animal, especially at close distances and on broadside hits that penetrate.
In this case, deputies wrote that Christenson was about 20 yards away, on his own property, behind a bush, with a steel fence dividing the properties when he fired. That’s the kind of shooting decision that raises more than one red flag for anyone who takes safe gun handling seriously: you don’t launch projectiles at something you can’t retrieve safely, and you don’t shoot where you don’t control the impact area—especially toward a neighbor’s yard.
The vet report is what turned it into a life-and-death situation
After the initial response, the victim called again to report she’d taken the dog to an emergency veterinary clinic. Veterinarians found multiple pellets in the dog, and those pellets had pierced its intestines.
According to the affidavit, the injuries were internally causing sepsis. The dog was given a 50/50 chance of surviving surgery. That’s a brutal outcome for an animal that, based on the report, was inside a fenced yard when it was hit.
A felony charge and a practical reminder for rural neighbors
Christenson was arrested July 6, 2026, and charged with Aggravated Animal Cruelty, a felony. The case, as laid out in the charging documents summarized in the report, hinges on a pretty straightforward chain: the video shows the dog’s reaction and direction of attention, the wound is consistent with a projectile injury, the suspect admitted to shooting, and the veterinary findings described multiple pellets and serious internal damage.
If you’re a dog owner, the practical takeaway is simple: cameras aren’t just for catching porch pirates anymore. They document fence-line problems, trespass issues, and the kind of “he said, she said” disputes that used to go nowhere. If you’re the neighbor dealing with barking, the other takeaway is just as plain: there are legal, sane ways to handle it—talking like adults, documenting repeated issues, working through county channels if necessary. When someone decides to take matters into their own hands with any kind of gun, they’re not just risking a cruelty charge; they’re creating a safety problem that can spin out fast in a tight neighborhood.
In the outdoors, we all like to think common sense will keep the peace. But this incident is a reminder that boundaries, documentation, and basic firearm discipline matter at home just as much as they do in the field.
