Indications

Credelio Quattro is indicated for the prevention of heartworm disease and the treatment and control of roundworm, hookworm, and tapeworm infections.

Important Safety Information

Lotilaner, an ingredient in Credelio Quattro, belongs to the isoxazoline class and has been associated with neurologic adverse reactions like tremors, ataxia, and seizures even in dogs without a history of seizures. Use with caution in dogs with a history of seizures or neurologic disorders. Dogs should be tested for existing heartworm infections before Credelio Quattro administration as it is not effective against adult D. immitis. The safe use in breeding, pregnant, or lactating dogs has not been evaluated. The most frequently reported adverse reactions in clinical trials were vomiting and diarrhea. For complete safety information, please see the Credelio Quattro product label or ask your veterinarian.

It’s recommended for my tiny 3 pounders even

It protects them against not only heartworms but also round, tape, hookworms along with flea and tick prevention. It’s my first time using this product. Approved

It protects them against not only heartworms but also round, tape, hookworms along with flea and tick prevention. It’s my first time using this product. Approved by 2/3 of my Chihuahuas. Tiny didn’t like it. It’s chewable so I had to put it in her food to disguise it. She is very picky eater.

Cheese Day

The 1st of each month is Cheese Day. That's when our dog, Birdie, gets a slice of cheese with her Credilio Quatro pushed into it. She is thrilled with her treat

It was larger than I anticipated.

My vet suggested it as it was supposedly more beefy flavored. Couldn’t get my pup interested. Had to shove down her throat and she vomited after. Next I’ll try cutting

My vet suggested it as it was supposedly more beefy flavored. Couldn’t get my pup interested. Had to shove down her throat and she vomited after. Next I’ll try cutting it smaller and hiding in cheese.
