Love the large "D" brass buckle. Might be interesting to research the tags and see what they belong to. I've dug more than a few of those rose bush thingies. Nice hunt mate.
Partner, nice finds. Those tags were on dogs being raised by a USDA ( United States Department of Agriculture ) licensed dog breeder. 23-A-0174 is the breeder's license number, and the numbers 329, 332, 313 were different dogs. Each dog had it's own number.
