No, assuming chow is an A record pointing to the IP address, and not a CNAME record pointing to a different hostname/subdomain. That's also assuming that chow is actually setup and defined, and there's no wildcard record for *.hound.com that would cause chow and anything else not explicitly defined to point to wherever the wildcard points. Basically, if you have: hound.com IN A ServerB.ip.address www.hound.com IN A ServerC.ip.address chow.hound.com IN A ServerA.ip.address Then no, changing either of the other two wouldn't affect chow.
