Can dogs eat chicken bones? Splinters, blockages and what X-rays show

A dog that grabs a chicken wing or a rib bone from the trash is a common emergency. Bones are not poisonous, but they can cut the mouth, get stuck in the esophagus, block the gut, or pile up in the colon. Here is what can go wrong, the signs to watch and when they appear, and what X-rays, endoscopy and blood work show.

The essentials

Dogs should not be given chicken bones or other cooked bones: cooked bones are brittle and splinter, and veterinary sources warn against raw bones too. Bones are the most common object that gets stuck in a dog’s esophagus, especially in small dogs and terriers. Signs of a stuck bone are gagging, drooling, retching and bringing food back up; a bone further down can cause vomiting, loss of appetite and belly pain hours to days later, or straining and blood in the stool. Bones show up well on X-rays. A bone in the esophagus is removed quickly, usually with an endoscope; many bones that reach the stomach are digested. Do not make your dog vomit and do not try home remedies: call your vet.

Can dogs eat chicken bones?

No. Cooked bones such as chicken wings or leftover T-bones can splinter and seriously injure a dog [17]; they are brittle and can cause blockages and perforations of the gut [19]. Raw bones are not risk-free either: they have caused fecal impaction, perforation of the esophagus or bowel, and broken teeth [19].

If your dog has swallowed a bone and gags, drools, retches, vomits, will not eat or seems in pain, call your vet now. Do not try to make your dog vomit: vomiting is not a suitable way to bring up sharp objects such as bones [2].

What a swallowed bone can do, from mouth to rectum

Bones are not necessarily toxic [16]. The danger is mechanical: sharp pieces can injure the mouth, esophagus and stomach and cause severe internal injuries, and bones can get stuck in the esophagus, the stomach, the windpipe or the intestines [15, 16]. Bones are digested only slowly [10].

Summary of veterinary references. A dog that swallowed a bone and stays well may have none of these problems: ask your vet.
WhereWhat can happenWhat studies and references report
Mouth and jawCuts, broken teeth, a bone ring stuck on the jawSharp bone pieces injure the mouth [15]; bones can break teeth [18, 19]; a beef marrow bone ring locked behind a dog’s lower canine teeth had to be cut off under anesthesia [18]
Esophagus (food pipe)The bone gets stuckBones are the most common esophageal foreign body in dogs [1, 2]: 88.6% of 44 cases in Dublin [3], 61.3% of 111 in Bangkok [8], 44% of 125 in a US study [7]; bones and rawhides were tied at 29.7% each in another series [4]
Esophagus, wallErosions, tears, scarringA tear can cause infection in the chest [1]; it was found in 12% of dogs with a stuck object [7]. A narrowing (stricture) is the most common complication [1]
Stomach and intestineBlockage, perforationBones can block the stomach or intestine [16]; a perforated gut can lead to infection of the abdomen (peritonitis) [10]
Colon and rectumConstipation, a torn rectumBone mixed with stool can form a hard mass that is hard to pass [13]; sharp bones can tear the rectum, causing straining and bleeding [14]

Bones are one of several foods that block the gut rather than poison it: see corn cobs and dogs and fruit pits and seeds. All the foods to keep from pets are in toxic foods for dogs and cats.

Signs to watch, and how soon they appear

  • Bone stuck in the esophagus: drooling, gagging, trouble swallowing, bringing food back up (regurgitation) and repeated attempts to swallow [1]. In 45 dogs with a bone in the esophagus, the most common signs were gagging, vomiting, regurgitation, loss of appetite and retching [2]. Water may still pass when food does not [1].
  • How fast: dogs in one series were seen a median of 2.75 hours after signs began [4]. Some dogs show nothing at first: 5 of 45 dogs were brought in after the owner saw them eat the bone, before any signs [2].
  • Bone in the stomach or intestine: signs may not be immediate. Hours to days later the dog may vomit, have diarrhea, be less active, refuse food and have belly pain [15]. Vomiting was the main sign in 83% of dogs with a bone in the stomach that had signs [2].
  • Bone in the colon or rectum: straining, hard dry stool, pain when passing stool and bleeding from the rectum [13, 14].
  • Breathing and coughing: a few dogs with a bone in the esophagus had breathing difficulty or coughed [2].

Waiting makes things worse. Dogs with a bone stuck for more than 48 hours had erosions of the esophagus in 16 of 18 cases, against 3 of 11 seen within 6 hours [2]. A foreign body in place for more than 24 hours was linked to severe inflammation of the esophagus and major complications [6], and dogs whose bone caused a tear were seen a median of 96 hours after eating it, against 24 hours for those without [7].

What the vet checks: X-rays, endoscopy and blood work

The vet asks what bone, how big and when, examines your dog and takes X-rays. Many objects stuck in the esophagus are visible on plain X-rays [1], and because most of them are bones, most are seen [3]. Blood work does not find the bone; it shows the effects of vomiting, dehydration or infection [10].

An annotated line from a lab report · Illustrative example
AbbreviationResultUnitLaboratory intervalFlag
Cl Chloride101mmol/L110–124L
  1. Abbreviation Cl or chloride, in the electrolyte block with sodium (Na) and potassium (K).
  2. Result 101 mmol/L in this illustrative line: below the interval. Low chloride was the most common change in dogs with gut foreign bodies, found in 51.2% [11].
  3. Unit mmol/L or mEq/L: for chloride the two numbers are the same.
  4. Laboratory interval The example uses the dog interval of the Merck Veterinary Manual [20]; each laboratory sets its own.
  5. Flag L: below the interval. Vomiting stomach acid loses chloride; with a blockage this often goes with low potassium and metabolic alkalosis [10, 11].
The tests depend on where the bone is and how the dog is doing. A dog that is well may need only X-rays.
CheckWhat it looks forWhat studies show
Chest and neck X-raysA bone in the esophagus, air or fluid in the chest after a tearThe object was clearly seen in 30 of 34 dogs [4]; a tear of the esophagus was seen on X-rays in 2 dogs of another series [3]
Abdominal X-raysA bone in the stomach or intestine, a blocked gut, bone in the stoolObjects that block X-rays, as most bones do, show on plain films [3, 10]; X-rays also show what the stool contains in a constipated dog [13]. X-rays gave a clear answer in 70% of vomiting dogs checked for a blocked intestine [12]
Abdominal ultrasoundA blockage, fluid-filled loops, free fluid or gas after a perforationGave a clear answer in 97% of the same dogs [12]; free fluid and gas suggest a perforated gut [10]
Endoscopy (under anesthesia)Sees the bone and the wall of the esophagus and stomachLets the vet check the damage and often remove the bone at the same time [1]
Chloride, potassium, sodium, blood gas, lactateLosses from vomiting, a blocked gutIn 138 dogs with gut foreign bodies: low chloride in 51.2%, metabolic alkalosis in 45.2%, low potassium in 25%, high lactate in 40.5% [11]
PCV and total solidsDehydrationOften high with a blockage (hemoconcentration) [10]; see the CBC for dogs
White blood cellsInflammation, infection after a perforationMildly high with gut foreign bodies; very high or low counts can be seen when a perforation has caused peritonitis [10]. See the white blood cell count
Abdominal fluid sampleInfection of the abdomenIf fluid is present, it is examined under the microscope for septic peritonitis [10]

Low potassium after vomiting is explained in potassium in dogs and cats.

Will the bone pass? Care and outlook

A bone in the esophagus should be removed straight away [1]. Most come out with an endoscope through the mouth: in 95% of 109 dogs [6] and 90.2% of 102 dogs [5]. If it cannot be pulled out, the vet may push it into the stomach, where bones can be digested [1, 2]. Surgery is needed if the bone will not move or the esophagus is torn [1]; in 63 dogs operated on, 74.6% went home [9].

The outlook is good when the bone is removed early [6]. In 114 dogs, 5 did not survive to discharge [6]; in 44 dogs, mortality was 11.1%, and 7 of 29 dogs followed long term had a narrowed esophagus [3]. Bone foreign bodies, a body weight under 10 kg and an object stuck for more than three days were risk factors for complications [5].

A bone in the stomach often does not need removal. In 84 dogs with a bone in the stomach, 74% were left in place to be digested, with no deaths from complications among the dogs followed up [2]. Bones further down are followed with repeated X-rays if the dog is stable; if a foreign body has not passed within 36 to 48 hours, stops moving, or the dog gets worse, it is removed [10].

Questions to ask your veterinarian

  1. Can you see the bone on the X-rays, and is it in the esophagus, stomach or intestine?
  2. Does it need to come out now with an endoscope, or can it be digested?
  3. Is there any sign of a tear in the esophagus or the gut?
  4. Are my dog’s chloride, potassium and white blood cell count normal?
  5. When should we repeat the X-rays, and which signs mean I should come back at once?

Frequently asked questions

Will a dog eventually pass a chicken bone?

Many bones that reach the stomach are digested: in one study, 74% of bones in the stomach were left in place, without deaths from complications among dogs followed up [2]. On follow-up X-rays, bones were gone within 1 day in some dogs and by 14 to 18 days in others [2]. There is no fixed time. A bone stuck in the esophagus will not be left: it must be removed quickly [1]. Call your vet rather than waiting.

Do cooked bones dissolve in a dog’s stomach?

Bones are digested slowly [10], and many bones in the stomach are dissolved without problems [2]. The largest study did not check whether cooked bones behave differently [2]. Cooked bones are brittle and splinter [19], and a bone stuck in the esophagus does not dissolve there: it needs removal [1].

How much bread should I give my dog after eating chicken bones?

None without your vet’s advice. Do not use home remedies and do not make your dog vomit: vomiting is not a suitable way to bring up sharp objects such as bones [2]. Call your vet, who may take X-rays to see where the bone is [15].

What bones are safe for dogs to chew?

No veterinary source we checked calls any bone free of risk. Cooked bones splinter [17, 19]; raw bones have caused impaction, perforation and broken teeth [19]; and ASPCA vets advise that bones in general should be avoided [18]. Ask your vet which chews suit your dog.

My dog ate a rib bone. What should I do?

Call your vet now, even if your dog seems fine. Rib bones are among the bones dogs often swallow [2], and signs of a blockage can appear hours to days later [15]. Watch for gagging, drooling, vomiting, refusing food, belly pain or straining. Do not make your dog vomit [2].
