Buster has done something else with his breakfast food bowl that amuses us. After walking him first in the morning, he goes back into his crate with his breakfast kibble and water bowls while I take Buffy our for her am walk.
Until I caught on to what was happening, he used the towel in his crate [that he sleeps on at night] to "bury" his food bowl with the towel. Sometimes he covered his water bowl, too, and then everything would get wet - he must not have learned about the wicking effect.
Because I was outside with Buffy, I came back to a scrunched up, very wet towel. At first, I thought that maybe he was peeing on it because of his separation anxiety. He would bark like crazy while I was walking Buffy [or so my DH reported. After several weeks he got used to the routine and stopped barking while I was gone.]. It turned out that the wet was from the water bowl, which was actually a big relief, all in all.
After doing this for a few days, I realized that the only way I could keep the towel dry - and not deprive him of fresh water - was to remove the towel before putting down the bowls. He has not complained, but I suspect that he misses having the towel there to bury his food.
