Frequently Asked Questions
My dog just threw up a worm. What do I do right now?
That's scary – take a deep breath. First, put the worm in a sealed bag or take a clear photo. Then check your dog's gums – are they pink? If they're pale or white, head to the emergency vet. Otherwise, call your regular vet in the morning for a fecal test and dewormer. Don't try to pull out any worms you see – you could hurt your dog.
How can I tell if my dog has roundworms or hookworms without a vet?
You can't be 100% sure without a microscope. Roundworms look like spaghetti and come out in stool or vomit. Hookworms are tiny and cause dark, tarry stool because they suck blood. Both cause a pot belly and poor coat. The only way to know for sure is a fecal flotation test at the vet.
How long can I wait before treating my dog for worms?
Don't wait more than a day or two. Worms multiply fast and can cause serious issues like anemia, especially in puppies. The sooner you start a prescription dewormer, the quicker your dog will feel better. If you see symptoms like diarrhea or weight loss, call your vet today.
Is it more expensive to go to the vet for dewormer than buying from the pet store?
Going to the vet might cost more upfront — maybe $50‑150 for a visit and medication — but it's actually cheaper in the long run. Over‑the‑counter dewormers often don't kill all stages and you end up treating multiple times. Plus, a wrong diagnosis can delay real treatment. Stick with the vet.
Can my dog die from roundworms or hookworms?
It's rare in healthy adult dogs, but yes, severe hookworm infestations can cause fatal anemia in puppies. Roundworms can also cause intestinal blockages. That's why prompt treatment matters — the risk is low if you catch it early and use the right dewormer. You're doing the right thing by asking.
I'm worried my kids might get worms from the dog. What should I do?
That's a valid concern. Roundworm eggs can survive in soil and infect people, especially kids who play outside. Here's what helps: deworm your dog as soon as possible, pick up dog poop daily, wash your hands after handling the dog or its waste, and keep kids away from areas where your dog poops. If your child has tummy aches or itchy eyes, mention it to your pediatrician.
