Yes, a dog can get sick from eating a bird. While many dogs snatch a wild bird and suffer nothing worse than an upset stomach, the real risks include bacterial infections, parasites, bone-related injuries, and in rare cases, avian influenza. The likelihood of serious illness depends on the type of bird, whether it was alive or dead when the dog found it, and how much was consumed.
Bacterial Infections Are the Most Common Risk
Wild birds carry bacteria in their intestinal tracts that can make dogs sick. The two most relevant are Campylobacter and Salmonella. Campylobacter, specifically Campylobacter jejuni, is considered a normal part of the gut flora in many bird species but causes intestinal infection in dogs. Dogs typically pick it up by ingesting contaminated raw meat or feces, and eating a whole bird covers both routes.
Symptoms of a bacterial infection from a bird usually show up within two to five days and look a lot like food poisoning: watery or mucus-filled diarrhea, vomiting, loss of appetite, and lethargy. Most healthy adult dogs with strong immune systems fight off mild infections on their own within a week. Puppies, senior dogs, and dogs with compromised immune systems are more vulnerable to severe or prolonged illness. If diarrhea contains blood or lasts more than 48 hours, that warrants a vet visit.
Parasites Birds Can Pass to Dogs
Birds serve as intermediate hosts for several parasites that can infect dogs. Two of the more significant ones are Toxoplasma gondii and Neospora caninum, both protozoan parasites. Birds of prey are especially exposed because they feed on infected small mammals and other birds, but common backyard birds can also carry parasitic organisms. When your dog eats an infected bird, the parasites gain entry to a new host.
Intestinal worms, including certain roundworm species, also use birds as carriers. A dog that regularly catches and eats birds has a higher cumulative risk of picking up a parasite load over time compared to a dog that did it once. Symptoms of parasitic infection may not appear for weeks and can include diarrhea, weight loss, a dull coat, and general fatigue. Regular fecal testing at your vet can catch these infections early, which is especially worth mentioning if your dog is a habitual bird hunter.
Bone Injuries and Obstruction
Bird bones are small and can splinter, particularly the bones of larger birds like pigeons or ducks. When a dog crunches through a bird carcass, sharp bone fragments can scratch or puncture the lining of the esophagus, stomach, or intestines. A perforation of the gastrointestinal tract is a surgical emergency.
Signs of an obstruction or perforation include repeated vomiting (especially if your dog can’t keep water down), a bloated or tense abdomen, visible pain when the belly is touched, drooling, and refusal to eat. These symptoms can appear anywhere from a few hours to a day or two after ingestion. Small birds like sparrows pose less risk simply because there’s less bone material involved, but the danger isn’t zero. If your dog swallowed a bird whole without much chewing, watch closely for any of these signs over the next 24 to 48 hours.
Avian Influenza: Low Risk but Worth Knowing
H5N1 bird flu has been circulating in wild bird populations and has spread to dairy cows, poultry, and some other mammals in the United States. The CDC considers the public health risk low as of early 2025, but dogs can technically contract avian influenza from contact with infected birds.
Signs of bird flu in dogs look different from a typical stomach bug. They include fever, fatigue, red or inflamed eyes, discharge from the eyes and nose, difficulty breathing, and neurological symptoms like tremors, seizures, loss of coordination, or even blindness. If your dog ate a bird that appeared sick or was already dead when found, and then develops any of these symptoms, seek veterinary care promptly. A dead bird lying in the open is more concerning than one your dog caught mid-flight, since birds that die from illness are more likely to be carrying a significant viral load.
Toxic Birds Are Extremely Rare
A handful of bird species worldwide actually carry toxins in their skin or feathers, but nearly all of them live far from typical backyards. The known poisonous birds include Pitohui and Ifrita species from Papua New Guinea, the European quail (which can become toxic seasonally depending on its diet), and a small number of others. Roughly a hundred additional species are considered unpalatable to predators. If you live in North America, Europe, or most of the developed world, the chance your dog ate a genuinely toxic bird is essentially zero.
What to Watch for After Your Dog Eats a Bird
Most dogs that eat a bird will be fine, but monitoring over the next few days matters. In the first 24 hours, watch for vomiting, gagging, drooling, or signs of abdominal pain, which could indicate a bone fragment causing trouble. Over the next two to five days, watch for diarrhea, loss of appetite, or lethargy, which point toward a bacterial infection. And over the following weeks, keep an eye out for ongoing digestive issues or weight loss that could signal a parasitic infection.
A single episode of vomiting right after eating the bird is normal. Dogs sometimes regurgitate feathers or parts they can’t digest. Persistent vomiting, bloody stool, a swollen belly, or any neurological symptoms like wobbliness or disorientation are the red flags that call for veterinary attention rather than watchful waiting.
