Tri-Heart® Plus (ivermectin/pyrantel) is a veterinarian-recommended, monthly chewable tablet designed for dogs weighing 51–100 lbs. It effectively prevents heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) and treats and controls common intestinal parasites, including roundworms (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense). The beef-flavored chewable is palatable, making administration easy. Suitable for dogs six weeks of age and older, Tri-Heart® Plus offers a safe and affordable solution for comprehensive parasite protection. Regular monthly dosing is essential for optimal efficacy. Before initiating treatment, dogs should be tested for existing heartworm infections, as Tri-Heart Plus is not effective against adult heartworms.

When our beloved fur-baby, Max, was diagnosed with glaucoma, our vet prescribed Latanoprost drops. Just one daily application has made such a difference! His eyes seem so much more comfortable, and it's a huge relief knowing we're actively protecting

My picky senior dog absolutely adores these NutriSource Lamb treats! Soft, wholesome, and real lamb, they're perfect for her sensitive teeth. Training is a breeze, and I feel great spoiling her.

Our dog hated brushing. Then, DuoClenz chews arrived! He devours these enzyme-coated rawhides, and his breath is noticeably fresher, teeth cleaner. It’s a brilliant, tasty solution for dental health.

My horse, prone to metabolic issues, was skeptical of healthier treats—until Omega Nibblers' apple flavor won him over. Low sugar, packed with omegas, and a shiny coat bonus! A smart, tasty choice.

When arthritis slowed our senior dog, our vet suggested Previcox. The tasty chewables were simple to administer, and we quickly noticed improved mobility. He's much more comfortable now.

My dog's tummy troubles were common. After introducing VetOne Neat Treats, his digestion improved noticeably. He enjoys the chews, and I appreciate their natural, effective support.
