I'll add a third. Difference is printing of the filename.
The two above depend on tail to print the name IF there
are multiple arguments. If there is only one match by find
or if xargs' last group no filename will be printed. This
could be avoided by adding /dev/null to tail's arg list.
The first solution above could exceed the system or shell's
maximum command line length.
ASolution where find prints the filename and calls a separate
tail for each file is:
find /foo -type f -name "*dog.dat" -print -exec tail -n 5 {} ';'
