Past tense of pet

[Douglas G. Wilson]

>Yet pet follows the standard short vowel, monosyllabic rule like put-put-put
>and set-set-set.

What rule is that?

A few verbs have this paradigm: "put", "set", "let". Some have it as a
'standard' alternative: "fit", "wet" (also "shit", "spit" maybe).

But: "I have net several fish, and I have gut them"? "I have vet his
report, and he has dot all his 'i's"?

"I have pet the dog today" cannot be standard, since I don't approve of it.
(^_^) It does occur repeatedly on the Web, but that's not called the "Web
of grammatical errors" for nothing. (^_^)
