Explore Dogline's Collars for Medium Dogs

Beagles, cocker spaniels, bulldogs, and other medium breeds need a collar that can keep pace with them, and that's exactly what Dogline delivers. We build our medium dog collars from premium materials like Biothane, leather, and nylon, plus trusted hardware from Herm Sprenger for pet parents who need proven training control, each reinforced with sturdy stitching so the fit holds up through pulling, playing, and everything in between. The Biothane styles are fully waterproof, so mud, drool, and dirt wipe right off without a second thought.

Getting the medium dog collar size right shouldn't take guesswork, which is why every design adjusts across multiple sizes and comes in a full range of colors to match your dog's personality. Looking for a dog collar for medium dogs that's a little more personal? Our personalized collars let you add your pet's name or your address, so they're always easy to identify, whether you're at the dog park or on a hike.

Dogline has built a reputation on high-quality, long-lasting gear that pet parents can count on. We ship every order within 24 hours, and our team is easy to reach by phone, email, or mail if you have questions along the way. Retailers interested in carrying our products can also inquire about wholesale partnerships. From everyday walks to training sessions, our medium dog collars are made to keep up.

Explore our full collar collection, pair your collar with one of our leashes, complete the look with a matching harness, or browse all Dogline products.
