Not as much as Mr. Brown enjoys doing it, because he really really enjoys it.
Sometimes he'll sniff her head when she lays down next to him and he'll pull back quickly as if she stinks, then he just dives right in and starts cleaning.
I can safely say however, his breath does not smell better than the top if her head.
I've watched him groom her till she passes out.
He uses that method more frequently when she has the bone he wants...
All I know is that I love when I'm able to catch a moment like this and then share my crazy love for my dogs with the rest of you!
Fiber related love coming soon!
