Max and Neo dog collar was recommended by a veterinarian. The "velcro," infinite number of adjustments, for a small dog, was the objective obtained with the purchase of the Max and Neo product. Have only used the collar for about 30 days, and, so far, it has met expectations. The Max and Neo collar is more robust than typical buckle type collars that only provide limited adjustment with the holes in the strap. The metal rings allow for attaching dog tags and a leash.
Only draw back was having to purchase 6 collars at a time. To date, 1 collar was used, 3 collars were sold at cost to other dog owners and 2 collars remain as excess for possible future sale.
