Momentous day for Cubby. He went from his puppy small tags to his big-boy tags on the swivel hanger so we get to see both tags. We have 1 tag with traditional contact, another with microchip data, and the county tag in between. Two custom pix of cabooses for double the fun from our favorite tag company Dog Tag Art. Age 19-1/2 weeks. Shaded sable sheltie. AKC Little Red Caboose.
I don't work for the tag company, I just think having custom color artwork on nearly indestructable tags is great fun. The ONLY thing that destroy these is puppy teeth. I bought a small size set (cat size) for the pup and his big boy set in the larger size (knowing he will be a large sheltie).
I use a collar with a breakaway or stretch feature for safety and walk on the Ruffwear Webmaster harness which is about the ONLY 100% inescapable harness on the market (as we proved in Morro Bay). He won't walk on martingale which I have used with my mature Melli girl & previous mature Aussies. I love the martingales, but having had Cubby slip out as well as Shay, I am no longer comfortable with anything but the ultimate harness, not for real world travels.
