IECOii Large Dog Coat with Built-In Harness, XXXX-Large Waterproof Reflective Winter Jacket

IECOii’s large-dog winter coat combines a built-in adjustable harness with a waterproof, windproof outer and an insulating polar polyester lining for cold-weather walks.

• Coat and harness in one — walk your dog without adding a separate vest harness.
• Waterproof, windproof outer with insulating polar polyester lining — helps keep your dog warm, dry, and clean in cold weather.
• Reflective straps across the back — improve visibility on low-light walks.
• Step-in design with a back zipper — makes dressing and removal more convenient.
• Two small back pockets — keep walking essentials close at hand.

Cold weather, rain, and snow can make everyday walks and outdoor outings less comfortable for large dogs. This coat is made for walks in different light conditions as well as activities such as hiking, camping, and hunting. Its integrated harness means the coat and walking harness are combined in one garment.

How do I choose the right size for my dog?

Choose size XXXX-Large by your dog’s chest girth first: it measures 47.24 in (120 cm) around the chest, with a 29.5 in (74.93 cm) back and a 29.5 in (74.93 cm) neck. The size is intended for extra-large dogs, with examples including Pyrenees, Great Danes, Mastiffs, and Saint Bernards. Measure your dog before choosing; chest girth is the primary sizing guide rather than breed or weight.

• Adjustable straps help tailor the fit.
• Compare your dog’s chest, back, and neck measurements with the coat measurements.

Does the coat have a harness built in?

Yes, IECOii combines the winter coat and harness, with an attached D-ring for leash connection. The straps adjust, and strengthened seams and the D-ring are designed to handle strong pulling. Reflective straps on the back help your dog remain visible in low light.

• The built-in harness removes the need for a separate dog vest harness.
• Reflective details suit evening walks and other low-light outings.

How does the coat go on, and what can its pockets hold?

The coat is a step-in style that fastens with a zipper along the back, making it easier to put on and take off. A protective fabric layer beneath the zipper helps prevent hair from getting caught, which can be useful for dogs that dislike pull-over coats. Two small pockets on the back hold compact walking items.

• Use the pockets for items such as poop bags, treats, keys, or small toys.
• The turtleneck collar adds coverage around the neck in cold weather.

This coat is suited to owners of extra-large dogs who want one garment for warmth, weather protection, and leash attachment during walks or outdoor activities. It is especially useful when a dog’s measurements match the XXXX-Large fit, since chest girth—not breed or weight—is the main sizing consideration.
