Different mode of action is what makes SAFE-GUARD (fenbendazole) so effective against the most dangerous parasites of the horse.

  • Works on a wide variety of parasites – Labeled for the control of large and small strongyles (including migrating larvae), pinworms and ascarids (roundworms)
  • High degree of safety – Safe for foals, pregnant mares and older horses1,3
  • Easy to administer – A unique apple-cinnamon flavor that horses readily accept1

 

  • The Mode of Action of SAFE-GUARD (fenbendazole) Paste 10% is due to the inhibition of energy metabolism in the parasite2
  • Available in two sizes: 25 gram and 92 gram

 

Indications

SAFE-GUARD (fenbendazole) Paste 10% is indicated for the control of large strongyles (Strongylus edentatus, S. equinus, S. vulgaris), encysted early third stage (hypobiotic), late third stage and fourth stage cyathostome larvae, small strongyles, pinworms (Oxyuris equi), ascarids (Parascaris equorum), and arteritis caused by fourth stage larvae of Strongylus vulgaris in horses.

Administration

 

SAFE-GUARD (fenbendazole) Paste 10% is administered orally at a rate of 2.3 mg/lb (5 mg/kg) for the control of large strongyles, small strongyles, and pinworms. One 25 gram syringe will deworm a 1,100 lb horse. For foals and weanlings (less than 18 months of age) where ascarids are a common problem, the recommended dose is 4.6 mg/lb (10 mg/kg); one 25 gram syringe will deworm a 550 lb horse.

For control of encysted early third stage (hypobiotic), late third stage and fourth stage cyathostome larvae, and fourth stage larvae of Strongylus vulgaris, the recommended dose is 4.6 mg/lb (10 mg/kg) daily for 5 consecutive days; administer one 25 gram syringe for each 550 lbs body weight per day.

Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.

 

Do not use in horses intended for human consumption. When using SAFE-GUARD (fenbendazole) Paste 10% concomitantly with trichlorfon, refer to the manufacturer’s labels for use and cautions for trichlorfon.

Highly Recommend for Aggressive Chewers!
I recently purchased the JAYU PET Toothbrush Toy Dog Chew Toy, and it has exceeded my expectations. If you’re looking for dog chew toys that are both durable and functional, this is a great choice. My dog is an aggressive chewer, and this toy has held up extremely well without breaking or wearing down. What I love most is how it helps clean my dog’s teeth while chewing. The textured design removes plaque and tartar naturally during playtime. It’s much easier than brushing my dog’s teeth manually, and my dog actually enjoys using it. This dog dental toy is perfect for small and medium dogs and keeps them busy for long periods, which helps reduce boredom and destructive behavior. It’s sturdy, safe, and clearly designed with dental health in mind. Overall, this is one of the best dog chew toys I’ve purchased—durable, engaging, and great for maintaining my dog’s oral hygiene. I will definitely be buying another one!

Not for aggressive chewers
My 14 pound puppy chewed a big chunk out within 30 minutes. Would not recommend if you have a dog that likes to tear into things

Not for aggressive chewers as labeled; poor quality
Really disappointed in this item. My barely 16 lb., 1 1/2 yr old labradoodle chewed right thru the plastic in literally 6 seconds. I was going to toss it but at $18, the item should live up to its description-this toothbrush toy is rated 80% on the aggressive chew scale as per packaging…NOT AT ALL! She bit off a couple off chunks immediately, then proceeded to bite off the spikes…couldn’t believe how quickly the toy was destroyed & I took it away within moments of giving it to her.

great for my dog
my 1 y/o pomeranian won’t let me brush her teeth. she also needs a lot of enrichment. i love putting a dollop of toothpaste, some wet food & few pieces of kibble in this toy for her. it keeps her busy for about 10 minutes and she really enjoys playing with it while consuming everything she can out of it. wonderful way to enrich while giving dental care. she is also a pretty good chewer and it’s still in one piece!

Terrific toy for puppies!
I love this dog toy! I put treats inside the soft teeth of the toy so that my puppies have to work to get them out. By doing so, they are cleaning their teeth and enjoying a mental challenge at the same time. I love watching them roll the toy across the floor as they try to figure out how to get the treats out. Adorable! And it keeps them occupied for a long time.
