So ... I am fostering a dog from the Humane Society for a couple weeks and I came home to find him out of his cage, tearing at the carpet with his paws. He was locked in a back bedroom, so the damage in in a straight line along where the bottom of the door was (a torn up area about 1/4 - 1/2 inch wide and 6 inches long). It isn't a huge hole, but it noticeable. I live in an apartment, so we don't have any remnants, but we do have the "strings" of carpet that were torn up (not sure what they are called, but they are the individual, now-loose strands of the carpet pile). Would it be a good idea to just get some super glue and carefully glue the strands back down onto the carpet backing? If not, how might I fix this in the least expensive way possible? I've thought about about going to a store, buying a remnant and patching it in, but the carpet is quite old and any new carpet would likely not match.
