Why is it called a pup tent?

Question

...lower, triangular single or snuggle tents!

Answer 1

Pup in this sense is the same as puppy "young dog". The notion was that such tents were so small and primitive that they were only fit for dogs (the term dog tent dates from the same period) or pups. The OED suggests that the tents were so named because they resembled dog kennels. Pup tents, as you know, are indeed small and of a simple A-shaped construction, basically two sheets of canvas or other material tied together. They were used in the military originally, and the term pup tent dates in writing from the U.S. in 1863, and it is likely that it was in use for some years prior to being written down.
