The Newport side have made a promising start to the season under new director of rugby Lyn Jones, with victories against Ulster and the Scarlets, but defeat to Munster and Edinburgh.
Zebre claimed their first win since being formed, with a thrilling 30-25 victory over Cardiff Blues a fortnight ago.
The Italian side were founded in 2012, and lost every match in their debut PRO12 season.
Lions No8 Toby Faletau is back in the Dragons' line-up, one of several changes in the forwards.
Second row Rob Sidoli, who makes his first start of the season, said: Zebre have "improved a lot. I think that they are a genuine threat as they had a really good result against the Blues which was away for them."
"They have some really good individuals and their core basics are very strong; they will have a good driving line outs and scrum so those are the things we need to get up to speed on quite quick.”
The Ospreys will look to maintain their unbeaten PRO12 start when they host Ulster at the Liberty Stadium tonight.

Ospreys Head Coach Steve Tandy said: "We are really pleased to be where we are in the table four weeks in and after three games on the road, but we aren’t going to allow ourselves to get carried away. There’s plenty of room for improvement."
"Ulster is as difficult as it gets. They’ve got a strong squad with world class players in there."
Ospreys began their Rabo Direct Pro 12 season with a hard-fought victory over Benetton Treviso, whose run of five successive home wins against Welsh sides came to an end at Stadio Monigo.
Tries from Scott Baldwin and Ben John plus 14 points from the boot of Dan Biggar sealed an important victory for the Ospreys, who were made to work hard for their victory by a determined Treviso outfit.
The hosts led 12-10 at the start of the second half following four penalties from Alberto di Bernardo, while they then reduced the deficit to two points heading into the final quarter of an hour through Simone Favaro's try but Biggar's penalty effectively settled matters.
Final score Treviso 19-24 Ospreys.

Head coach Steve Tandy has said is "crucial" the Welsh side start their season better than they did last year, when early defeats left the out of touch with the play-off spots.
"It’s a tough start. Treviso beat every Welsh team at home last season, and we lost twice out there, so we know that we have to be at our best from the very first whistle," Tandy said.
Tito Tebaldi makes his competitive debut at scrum half, after Samoan star Kahn Fotuali'i left for Northampton.
