Powerful Protection Against Fleas and Parasites

Overview:

Stronghold for Dogs offers a comprehensive solution to protect your pet from fleas, heartworm, and other harmful parasites. This easy-to-apply spot-on treatment ensures your dog stays free from the discomfort of infestations, while also guarding against internal parasites like heartworms and intestinal worms. Perfect for dogs of all sizes, Stronghold provides lasting protection with a single monthly dose.

Key Benefits:

  • Kills adult fleas, flea eggs, and flea larvae to break the flea life cycle.
  • Prevents heartworm disease by killing heartworm larvae.
  • Treats and controls ear mites, sarcoptic mange, and certain intestinal worms (roundworms, hookworms).
  • Waterproof formulation for protection even after bathing or swimming.
  • Easy, convenient, and stress-free spot-on application.

Active Ingredients:

  • Selamectin: The key active ingredient, Selamectin is a broad-spectrum antiparasitic that works by disrupting the nerve and muscle function of parasites, killing both external parasites like fleas and mites as well as preventing heartworm infections.

Product Variants:

Stronghold for Dogs comes in multiple dosages tailored to the size and weight of your dog, ensuring precise treatment for optimal effectiveness. Available variants include:

  • Very Small dogs (5 to 10 lbs)
  • Small dogs (10 to 20 lbs)
  • Medium dogs (20 to 44 lbs)
  • Large dogs (40 to 90 lbs)

Usage Instructions:

Apply the appropriate dosage based on your dog’s weight once a month. Part your dog’s fur at the base of the neck between the shoulder blades and apply the entire content directly to the skin. Do not massage into the skin. Ensure that your dog stays dry for at least 2 hours after application. Consult with your veterinarian before using this product on puppies under 6 weeks old, pregnant, or nursing dogs.

Easy to use and keeps my cat flea free

Written by Jessica Morgan

I’ve been using Stronghold for my cat for a few months now and it’s been great. The application is really simple—just a quick spot on the back of the neck once a month—and my cat doesn’t seem bothered by it at all. Within a day or two I noticed the scratching had stopped, and I haven’t seen any fleas since. I also like that it covers more than just fleas, which gives me a little extra peace of mind. Overall it’s been an easy and reliable treatment, and I plan to keep using it.

Great Product

I've been using this product for years on both my dog and cat (he's indoor/outdoor) with no side effects. Very good at flea control. Decent with the ticks too, although the pets can still carry them in the house and I'll find ticks (3 or 4 per year) crawling up the curtains and walls in late July and August. I think that is just because we haven't had severe winters the last 3 years and the insects survive better. I like that it covers worms and lice too. I am so thankful that I can buy it here at Pet Shed for the best price available! Highly recommended!

fantastic
