We consider your pet as a member of your family. It has always been our mission to produce and provide professional dog products. Reasons for choosing us: Personalize your dog's collar: Sew your pet's name and number on the collar so it can be quickly identified and not lost. In addition, you can customize other text creatively. Note that custom text is limited to English letters and numerals. 2. Quick Location collar: Two reflectors on the collar help identify and locate your dog, even at night. Best for people who walk dogs at night. 3. Multiple collar and line colors. Collar color: pink, black, blue, cyan, green, purple. Line colors: black, yellow, royal blue, grass green, gray, purple, rose red, sky blue, red, white and orange. 4 sizes: extra small (8."-12"), small (11"-18"), medium (12"-18"), large (14"-22") * Measure your pet's neck * To make sure your dog's collar is the right size, measure it with duct tape or string and wrap it tightly around the base of your dog's neck -- so comfortable that you can't place any tape measure on your fingers. Your pet must measure its neck size to fit an adjustable collar length. For example, if your dog has a 13-inch neck, get an 11 - to 16-inch adjustable collar. In some cases, when adjusting the collar down there is a possible adjustable slider that can rest in some custom embroidery. We are recommended to use capital letters in the text and not to choose the same color as the collar of the embroidery thread for the better results and the better readability.
