There’s no doubt that dogs are incredible creatures. They’ve been man’s best friend for thousands of years, and they continue to prove their loyalty every day. But one thing they’re not is picky eaters, and sometimes this can be bad news for their health. Dogs will pretty much eat anything if it looks like food, even if it’s the size of a small boulder. But how big is too big? What exactly can dogs digest? And what happens if they eat something that’s too large?

You may have heard that dogs are able to pass large rocks, or even boulders, in their intestines without any negative health effects. This is true, but there are some conditions that must be met for this to happen safely.

First, check with your vet before you give your dog anything larger than a baseball-sized rock (or a grapefruit-sized rock if you’re planning on giving it to your cat). There are many factors that go into determining whether or not your dog will be able to pass the rock without any issues, and your vet is the best person to assess these factors.

How Big Of A Rock Can A Dog Pass

Small rocks aren’t an issue for dogs. They can safely pass rocks of approximately 1.5 inches in diameter. Some pet owners report their dogs successfully passing rocks that are twice as large. Smooth river stones navigate the gastrointestinal tract more easily than sharp ones, which could cause internal damage. Here are some tips to prevent small rocks from getting into your dog’s intestines. Listed below are some prevention and treatment options:

Small rocks

If your dog accidentally swallows a rock, he or she may vomit the stone in an attempt to expel it. Although it may not seem serious at first, your dog may experience vomiting as a result of the stone blocking the intestine. Though your dog will continue to poop and eat, you may notice that the dog has trouble swallowing, and your pet is showing signs of indigestion and tarry stools. It’s important to consult a veterinarian to determine the cause of the obstruction.

Stones in a dog’s poop will most likely be small and of varying sizes. It will eventually pass out of the dog’s intestines, but too many stones can cause intestinal blockage and choking. The first step is to check your pet for symptoms of a stone blockage and seek emergency care from your veterinarian. However, if the stone has not passed yet, the best option is to leave it alone.

If your dog is eating rocks, it is important to identify and treat the underlying causes. If the rock is a golf ball-sized stone, the chances of a blocked intestine are high. You can prevent the rocks from reaching the intestines by teaching your dog to ignore them. Alternatively, a dog may be distracted by a ball that’s not meant to be eaten. Small rocks that a dog can pass may be a sign of boredom, and it is advisable to provide your dog with a suitable chewing toy to keep him busy.

If you see a rock in your dog’s intestines, it’s important to seek veterinary attention. An intestinal blockage caused by a rock can result in dehydration, weakness, and even an ulcerated stomach. In addition to damaging the digestive system, rocks can cause other problems, including diabetes and parasites. If you notice any of these symptoms, your veterinarian will recommend the appropriate treatment.

The most common reason for dogs to chew on rocks is for exploration. This behavior is common in puppies and young dogs because their mouths are more open and they like to stick things in their mouths to explore. However, once your dog becomes bored with the behavior, it’s likely to change to other things to keep itself busy. If a rock is ingested whole, the resulting dehydration or infection could be life-threatening.

Intestinal blockages

A stone, or any other object large enough to stop a pup from passing food, can cause an obstruction. The most common obstruction is a foreign body, but there are also other possible causes, such as string or rope fibers, which may twist in the intestines. Tumors and masses are also common causes of bowel blockages in older dogs. Most dogs can pass through small rocks on their own. However, if the rock is too large to pass through the intestines, the veterinarian may perform a gastrotomy to remove it.

A partially blocked intestine can take a few days or weeks to pass. Although the typical symptoms of a blockage are present, the dog may not exhibit any of them. If your dog passes a small object in its stool, it will be easy to determine how large it is. The only problem is that this method is very icky. In some cases, it’s not possible to tell how large the object is.

Surgery to remove an obstruction can cost up to $800 or more. The cost depends on the extent of damage, the type of medication used, and where the surgery takes place. Regardless of the method chosen, intestinal blockages require the care of a veterinarian, and the sooner your dog receives treatment, the better. In the case of a true blockage, surgery may be necessary. You should consider using Care Credit to pay for the procedure, since many veterinarians are willing to accept it.

The procedure to remove an obstruction involves inserting a small tube with a camera through a dog’s stomach or throat. A veterinarian will perform this procedure while the animal is sedated. Once the foreign object is located, you can choose between surgical and non-surgical treatment options. Treatment depends on factors such as the size and location of the foreign object, how long it’s been stuck, and its shape. In some cases, your vet may simply remove the object through the endoscope and perform other procedures, such as X-rays and ultrasounds.

If your dog swallowed a rock, the first step is to visit a veterinarian. They will perform a physical exam and possibly order blood tests to determine the cause of the obstruction. If you have any suspicions, a trip to the vet’s office will be in order. The sooner the vet can remove the foreign object, the better. Otherwise, it will become a serious complication.


If your dog is choking on a rock, you may be wondering, How big of a stone can a dog pass? There are two primary options – you can wait until the rock passes, or you can go to the vet and have him or her check it out. A partial obstruction may take three to four weeks to pass, but the outcome is always negative. Whether your dog can pass a stone depends on the severity of the problem.

Most dogs can safely pass rocks that are 1.5 inches in diameter. Larger dogs can eliminate rocks as large as two inches in diameter. Depending on the type of rock, the size may vary. Smooth river stones are easier to pass through the gastrointestinal tract than rocks with sharp edges, which can cause internal damage. If your dog passes a rock of the right size, it will be passed without any trouble.

Fortunately, most rocks can be passed without any problems, but some dogs can’t tolerate them. Large rocks are particularly dangerous, since they can block the digestive tract. Your dog’s intestines are sensitive, so any foreign objects may have to be surgically removed. If the rock is small, you can induce vomiting, but only if you’re confident in your ability to do so. For best results, make sure you’ve tried this option before.

Once your dog is trained to avoid the rock, it will be much easier to prevent it from passing through the intestines. Using the command “drop it” will help your dog avoid ingesting rocks, and will reduce the risk of expensive surgeries. If your dog refuses to swallow a rock, play fetch with it or even play tug of war. Your dog may even start vomiting after swallowing it.

Whether your dog is eating rocks or not, it may be difficult to determine whether the rock is too large or too small to pass. Even if your dog doesn’t seem to have a problem with small rocks, it’s important to avoid any kind of foreign bodies. If a stone reaches the colon, it can impede stools from passing through, causing vomiting, lethargy, and other symptoms.


How big of a rock can a canine pass? Most dogs can pass rocks up to 1.5 inches in diameter, although a large breed may have trouble eliminating such stones. The shape of the rock is also important, as smooth river stones may pass through the gastrointestinal tract more easily than rocks with sharp edges. A dog may choke if a rock blocks its airway, which could cause intestinal blockage.

If your dog is unable to pass the rock, you should seek help. Surgical procedures can cost up to $2,000 for the blockage, and you’ll also have to spend time and money on massive antibiotics. A veterinary visit can also be expensive, so a stone is not worth the risk. If you’re unsure of your dog’s health, you can try to avoid letting the stone get too big by using a rock crate.

If your dog is not throwing up the rock, you can work on behavior modification. Positive reinforcement and training can help eliminate this behavior. Moreover, a trip to the vet can help diagnose the problem, determining whether it is a nutrient deficiency or a parasite. In the latter case, a vet can prescribe nutritional supplements and medications to treat parasites.

Symptoms of intestinal blockage include dehydration, weakened limbs, and vomiting. The dog may also become lethargic and show signs of discomfort. Vomiting and diarrhea are often the first signs of a serious digestive problem, and turning down food and water is a sure sign that your dog is suffering from an intestinal blockage. The condition is also accompanied by constant urge to vomit.
