Common Signs of Worms in Dogs
As a pet parent, it’s unsettling to think your dog might have worms. But knowing the signs can help you catch an infection early. Worms are internal parasites that feed on your dog’s nutrients, causing a range of symptoms. Here’s what to look for.
Visible Signs in Stool or Around the Rear
One of the most obvious signs is seeing worms in your dog’s feces or vomit. Roundworms look like spaghetti, while tapeworm segments resemble grains of rice. You might also notice your dog “scooting” – dragging its rear on the ground – due to irritation from tapeworm segments. Check your dog’s bedding for small, moving segments.
Changes in Appetite and Weight
Worms steal nutrients, so even if your dog eats normally (or more than usual), it may lose weight. Conversely, some dogs experience a poor appetite. Hookworms and whipworms can cause chronic weight loss and poor body condition.
Digestive Upset
Vomiting, diarrhea, or a pot-bellied appearance are common, especially in puppies. Diarrhea may contain mucus or blood, indicating hookworms or whipworms. If your dog shows these signs, a vet visit is important.
Lethargy and Dull Coat
A dog with a heavy worm burden may seem tired and less playful. Its coat might become dull and dry. This is partly due to malnutrition from the parasites.
When Should You Consult Your Vet?
If you notice any of these signs, schedule a vet appointment. Puppies and dogs with severe infections can develop anemia, intestinal blockages, or other complications. Your vet will examine a fecal sample under a microscope to confirm the type of worm. Do not use over-the-counter dewormers without a diagnosis – they may not target the specific parasite and can be ineffective.
What Happens During a Vet Visit?
Your vet will ask about your dog’s symptoms and lifestyle. A fresh stool sample is ideal, but if you can’t collect one, the vet may use a rectal swab. They’ll look for eggs under a microscope. Treatment typically involves a prescription dewormer that kills the specific worms. Puppies often require multiple doses. After treatment, your dog may pass dead worms in stool for a few days.
Preventing Future Infections
Prevention is key. Use monthly heartworm preventives that also control intestinal worms (most are effective). Keep your dog away from feces of other animals, and practice good hygiene: pick up after your dog and wash your hands. Do not let your dog eat rodents, which can carry tapeworms. Regular vet checkups with fecal exams at least once a year help catch infections early.
Remember, while many worm infections are treatable, some can be serious. Always consult your vet if you suspect worms.
Key Takeaway
Watch for scooting, visible worms, weight loss, and digestive upset, and always consult your vet for proper diagnosis and treatment.
