Breaking news from the Gosh, I Need A Life department:
I just realized today that I've come to recognize the various chewing sounds the dogs make. Emma, especially, tends to lay on the floor behind my recliner and chew whatever's close at hand. The Nylabones are very hard plastic (AND bacon flavored, might I add), and they make an appropriately irritating tooth-on-bone scraping sound when being gnawed. Rope, the dogs' beloved rope bone, squeaks as the fibers are pulled between Emma's teeth. Hot Dog Squeaky toy is a rubber squeaky toy, so that's not hard to figure out. Oh....And when Rabbit is treated for his numerous dog-induced injuries and sent back to the front lines, well, he's easy to discern thanks to the squeakers embedded his body.
The wisdom of this last toy was obvious after Emma systematically destroyed three other fuzzy squeaky toys. Rabbit has very long legs and ears, providing an excellent flop factor, as I dubbed it. He can be shaken roughly by any appendage or ear and he has a suitable dead-animal flop the dogs both seem to enjoy. (How do they fling their heads and necks around like that without getting a major dislocation, anyway!?) The second reason Rabbit was an exellent choice is the three separate squeakers in his body: one in his ample midsection, and one each in one foot and one hand. The advantage of this redundancy? Even if the dogs dismember this fella, they still have at least three squeaky toys, nomatter how odd the parts look when separated from the whole.
Any other sound - especially that which sounds like plastic wrap, tinfoil, plastic yogurt cups, tuna cans or, worse, like something too small to produce anything but lip-smacking sounds - is cause for immediate investigation. A twist tie or paperclip, though fun, can be deadly.
