I’M Ollie. This is another instance where the absence of dogs on the CAFC led to a wrong result. Look at this reasoning, from page 12:
. . . the verbs “wag” and “beg” both suggest dog behavior, and in particular both convey the excitement exhibited by dogs during feeding. Although the Board acknowledged that the mark BEGGIN’ STRIPS also suggests “bacon strips” to some consumers, the Board reasonably concluded that the implicit reference to “bacon” did not detract from the similarity of the two marks in both sound and meaning.
Typical human imprecision.
