I have 4 of these colorful collars and they are my favorites by far. . We always get compliments when we are out on our hikes because they are so bright and lively. The new metal magnetic buckle is fantastic. Maui, my 1.5 year old Vizsla is a true hunting dog and she is constantly running through thick brush and chasing anything that moves. The new magnetic buckle can withstand even Maui. : ) The collars are also very easy to clean so they always look like bright and fresh. I highly recommend these collars and the new metal magnetic buckle not only stays on, but makes the collars look extra fancy. Vicki has such a wide variety of colorful designs, it is hard to pick just one, which is why we have 4!
