If you don’t have one, here is a tape measure you can download and print: https://z5d9i3t2.stackpathcdn.com/wp-content/uploads/2020/11/measuringtape-A4.pdf
While your dog is standing – measure snugly around your dog’s neck where the collar would sit. Take this measurement and then add 1″/2cm. This is the collar size for your dog. Remember your dog needs enough space for 2 fingers to fit between the collar and their neck for a comfy fit.
Please note: We cannot advise you on what size to buy for your puppy. Puppies grow at different rates and mixed breed puppies can take after their mother or father. For example: A cockerpoo can be bred with a standard or miniature poodle. Your pup may take after their spaniel parent or their poodle parent and their size is determined by the breed of poodle. Our best advice is to measure.
