Comparision of the voice over actors who have been the voice of Dukey with sound clips and images.
Franchise: Johnny Test

Dukey is a mixed-breed dog belonging to the Test family. Due to genetic enhancements by Susan and Mary Test, Dukey is highly intelligent and capable of speech. To take advantage of the widespread low intelligence and/or common sense of the show's inhabitants, Dukey claims himself to be a human with a rare hair disorder to throw off any suspicion of his true nature. Dukey would act as the voice of reason to Johnny, Susan and/or Mary Test if any of them actually listened to him. Despite Johnny's overwhelmingly callous and selfish behavior, attempting to do harm to Johnny's well-being is known to set Dukey off.

Dukey is voiced by Louis Chirillo for the first four seasons of the show. Due to Chirillo's retirement from voice-acting, Trevor Devall took over the role starting with the fifth season.

Chirillo's acting as Dukey is certainly spirited, even if the yelling doesn't exactly help the show's notoriously obnoxious nature. Devall's Dukey is noticeably lower-pitched, which actually makes his performance a bit easier on the ears even if it is a little less distinctive.

The pros and cons of each performance are too even for me to call a personal vote. Plus, I simply don't care for the show or its characters enough for me to latch onto a performance.

The show is honestly not that good (at least, after the first season, which was actually OK), but Louis Chirillo gave Dukey a lot of spunk and charisma in his performance.

Trevor Devall's performance is tolerable, though, it was similar enough to Chrillo's while also making the role his own and a little more toned down.

I want to give this one to Trevor just because Louis would sometimes overact as Dukey.

Louis Chirillo had more energy and enthusiasm so I pick him, but I didn't mind Trevor Devall, he did okay as well.

1. Louis Chirillo: Full of energy and great acting, even if at sometimes the emotions were over acted.
2. Trevor Devall: Not exactly like Chirillo's excellent performance but he did a great job making this role his own.

@Axx Chirillo left to be with his wife in Brazil and since Devall played Dukey for a video game the creator's decided to have him voice Dukey for seasons five and six.

I preferred Louis Chirillo's performance in the role of Dukey. He made the character enjoyable and energetic.

Trevor Devall's voice for Dukey often reminds me of Ian Corlett's voice for Hugh Test. It does not compare to the voice provided by Louis Chirillo.

I'm more used to Louis Chirillo, so I'll go with him.

I don't care for the show either and I don't like the name Dukey since it has another meaning (hopefully you know what I mean) but I think Louis is a little better.

@JayGirl10 I wonder what you mean. o.o

I'm getting used to Devall's role as Dukey, but Chirillo's will always be a favorite...

I'll go with Louis since I'm used to him from when I watched it on the WB/CW before it went over to CN after I didn't watch it at all.
