My dog has worms in her poop. Is there an affordable OTC dewormer?
You can't visually tell the difference between hookworms and roundworms. Thankfully, treatment is similar. You can use an OTC dewormer like the one linked below. Make sure to follow the label directions and repeat in 3-4 weeks to completely clear the worms. https://www.petsmart.com/dog/dental-care-and-wellness/treatments/sentry-worm-x-plus-7-way-broad-spectrum-dog-de-wormer---2-pack-13328.html

My dog is at the weight limit for flea/heartworm meds. What dose?
Sentinel has no tick coverage and does not kill fleas. It only sterilizes the eggs. I always go up a size to be safe as most dogs gain weight but rarely lose weight. It has a good safety margin so using the 25-50 pounds medicine would be best. You will continue to need the Simparica or nexgard with this

Vet Q & A
Can I give my dog Sentry Worm X Plus for hookworms while on Tri-heart?
Yes this should be fine and shouldn't cause him any harm. I just wouldn't give them on the same day. You will need to deworm today and repeat it in 3 weeks to help get ride of the hookworms. I would then have your vet check a stool lsample to ensure they are gone. I hope this helps!

Vet Q & A
Best flea/dewormer for puppy bathed often and sensitive to pills?
Hi there. Since you bathe Sophie so often, a topical flea medication/dewormer is probably not a great choice. Based on what you're looking for, I would suggest using Heartgard or Sentinel for heartworms and intestinal parasites, along with Nexgard or Bravecto for fleas and ticks. Vomiting is a common side effect with Trifexis, but is not usually seen with other oral flea/tick or heartworm medications - most dogs tolerate all of the products listed above with no problems :)

Vet Q & A
What's the best broad-spectrum dewormer with easy dosing for dogs?
Panacur (fenbendazole) is probably one of the best broad spectrum dewormers. It treats hookworms, whipworms, roundworms and some tapeworms. It is also used to treat Giardia and lungworms. You will need to contact your veterinarian for a dose based on your dog's body weight. Legally, we are prohibited from recommending doses for medications in the absence of a physical exam and a VPCR (veterinarian-patient-client relationship).
