Collars can be washed at 30°, just hang on the line or radiator to dry.
Clasps for 1 inch width collars are 1.5 inches, and for ¾ inch width collars clasps are just over an inch.
If you are unsure of the size you need, place a piece of string around your dog's neck and insert two fingers to make sure it is not too tight, and measure from this. For maximum comfort you will want the size closest to the higher end of the scale. So if your dog's neck measured 13 inches you would order a small rather than a medium, and if it measured 17 inches you would want a medium and not a large.
Love this print? Why not pair it with the matching yellow Polka Dot Dolly dog lead and slip-on dog bandana?
