There is nothing spectacular about it. I advise either bringing a tiny, airtight bag to collect feces whenever you walk your dog, or scoop out the cat's litter box soon before a visit to the clinic. Pick up a little piece, using the bag as a glove. Using a plastic spoon to gather a small quantity to put in the bag may also be a good idea. If possible, obtain a sample no later than six hours before the visit. A fresher specimen is preferable for detecting eggs and larvae. If it will take more than a few hours, put it in two or three bags, and keep it in the refrigerator until you're ready to depart. If your pet doesn't go potty the morning of or in the afternoon of the exam, then your veterinarian would appreciate receiving a fresh sample whenever it's practical. So, don't worry if you have to bring it at a different time. If you have many pets sharing a litter box or a bathroom, bring in three different samples just to be safe. You don't need to give your veterinarian the entire stack; less than one teaspoon will be sufficient for the test. Simply place a small quantity in the bag, tightly seal it, and discard the remainder.  Don't get upset if something shows up on your pet's fecal test because around one-third of pets at some point have worms or bacterial infections.  Additionally, always bring a stool sample with you if you're either bringing your pet in for an annual checkup or to be treated for nausea, vomiting, or lethargy. It's crucial for your pet's health and the health of everybody in your household to get their stool examined annually.
