Brand new no tags attached just didn’t fit my dog so we put my dog in a small… but this is Sarah the best harness and the only one I can use on my dog Size M Color is black and turquoise Dog harness is specially designed for small breed dogs, with the largest size fitting dogs up to 35 lbs. The no-pull design reduces space around the back, making it harder for your dog to escape during walks. The convenient, step-in design allows your small sidekick to easily step in to and out of the harness. Machine washable for easy cleaning. Lightweight, durable harness comes with a POM plastic leash ring.
