The product I like the most is the 3/4 in. Day Glow D-End Puppy / Small Dog Collar - it's the perfect size for my dogs. It comes in even neck sizes from 12-18 inches, which will fit neck sizes 9" to 19". The collar is a reasonable $8 and comes with a free brass plate with 4 lines of your choice. They also have it in a 1" width if you like a wider collar. The size of the dog's neck is the collar size, so make sure you measure before you order. They are long-lasting and having the ID tag riveted to the collar is a great thing. And it works! We had Travis the cocker take a tour of the neighborhood and invite himself to a backyard barbecue once, and because our name and phone number were on the tag, we were called within minutes of his going missing. Most recently, we ordered kennel sunscreen covers for the tops of our outdoor Mason runs. They work great, and also keep Kian from jumping out of the runs.
