The habit nobody mentions
Why does my dog eat poop?
It is the question families are embarrassed to ask on the phone, and it is one of the most common. It is also one of the more fixable habits, once the dog stops getting the chance to practice it.

The answer
Mostly normal scavenging, sometimes a learned habit, occasionally a medical signal.
Eating feces has a name, coprophagia, and it is common in dogs, especially puppies. A mother dog cleans up after her puppies for weeks, and puppies explore everything with their mouths. Many dogs outgrow it; some do not. Droppings from other animals, cat litter, goose droppings by a lake or horse manure on a trail, are the most tempting of all to many dogs, and that is a scavenger's instinct at work, not a sign that something is wrong.
A habit forms when the opportunity is always there. A yard that is picked up once a week gives a dog dozens of chances. A dog that was scolded for accidents in the house may learn to clean up the evidence. And a bored dog alone in a yard all day finds its own entertainment, some of it unpleasant. The longer the habit runs, the faster the dog gets, and some dogs learn to grab a mouthful the moment the owner looks away.

Vet first when
A sudden start, weight loss or a dog that always seems starving belong with the vet.
Some medical problems can make a dog hungrier or change how well it absorbs food, and a dog in that state may scavenge more. If an adult dog starts eating stool out of the blue, is losing weight, has changes in its own stool, or seems ravenous all the time, book a veterinary visit and bring a sample. Eating other animals' feces can also expose a dog to intestinal parasites, so ask your vet about regular fecal checks.
Diet questions belong with the vet too. Plenty of products claim to make stool unappealing; your vet can tell you whether anything is worth trying for your dog. Training and management are what change the habit, whatever the vet finds, so start them alongside the visit rather than waiting on it. Feeding at set times, rather than leaving a bowl out, also helps you and the vet see whether the dog is genuinely hungry or simply grabbing what is there.

What to do
Remove the chance, supervise the yard, and pay the dog for coming away.
Start with management, because every mouthful makes the habit stronger. Pick up the yard right after the dog goes, every time, and walk the dog out on a leash for potty breaks for a few weeks so you are right there. Move the litter box behind a baby gate or into a spot the dog cannot reach. On walks, keep the leash short past goose-heavy lake edges and trail droppings.
Then teach the dog a better habit. As soon as the dog finishes, call it to you and pay with something great, so the routine becomes go, turn to the owner, get a treat. Teach leave it at home with food on the floor, then in the yard, then on walks. Never scold a dog for eating stool or for accidents, because that is how the hide-the-evidence habit starts.

The Houston factor
Goose-lined lakes, deer trails and yards that need a daily sweep.
Many master-planned neighborhoods around Houston are built around lakes, from Towne Lake and Bridgeland in Cypress to Cinco Ranch in Katy, and the geese and ducks that live there leave droppings along the paths. The Woodlands and Kingwood trails add deer, and acreage in Tomball and Magnolia adds horses and livestock. A dog that scavenges has plenty to find on a normal walk here.
In the heat, potty breaks happen early and late, and it is tempting to let the dog out alone and skip the cleanup. A few weeks of leashed trips with a bag in hand stops the practice. Mosquitoes are a year-round issue too, so ask your vet about heartworm prevention if your dog spends a lot of time outside.
At Best Dog University
Lessons fix most cases, and Gold helps the dog that needs structure everywhere.
Most dogs that eat poop do not need a board and train. A private lesson at $160 in Cypress or $220 in your home is usually enough to set the yard routine, the call-away and a solid leave it, with the rest done by the family. A puppy under four months gets it built into the Puppy Development Bundle at $550 or $750. A dog that scavenges everywhere, pulls toward every smell and has no real impulse control benefits from the two-week Gold program at $2,500, where impulse control is built daily and handed over at the go-home session.

Asked and answered
Questions people ask about this.
Will my puppy grow out of eating poop?
Many puppies do grow out of it, especially when the yard is kept clean and the habit never gets established. Some carry it into adulthood. Clean up right away, supervise on a leash, and teach a call-away and leave it now, while the habit is still young.
Why does my dog eat cat poop?
Cat food is rich, and many dogs find cat litter irresistible. It is a scavenging habit, and the answer is access: put the litter box behind a baby gate, in a room the dog cannot enter, or use a covered box that the cat can use and the dog cannot reach.
Is it dangerous for my dog to eat poop?
It can be. Other animals' droppings can carry intestinal parasites, and a dog that eats a lot of it may get an upset stomach. Talk to your vet about fecal checks and prevention, especially if your dog regularly eats wildlife or other dogs' droppings.
Does punishing my dog stop it eating poop?
Usually not, and it can make it worse. A dog punished for accidents or for eating stool may learn to eat it faster or out of sight. Supervision, a clean yard and a well-paid call-away work far better than scolding.
