"Teen Mom 2" just suffered another casualty -- this time in the form of an advertiser -- Greenies pet treats has cut ties with the MTV show.
In a statement Friday, Greenies announced, "We have zero tolerance for animal cruelty and we can now confirm that as a result of this incident, our ads will no longer run during Teen Mom programming."
Greenies joins a mountain of companies who have pulled the plug on their relationship with "Teen Mom." Chipotle, Dove Chocolates, TWIX and Persil ProClean are among some of the brands who have also cut ties.
TMZ broke the story ... "Teen Mom 2" star Jenelle Evans' husband, David Eason, is under investigation for animal cruelty after he allegedly pummeled and then shot his family dog. Both the local Animal Control and Sheriff's Department is working on the investigation.
We reached out to MTV for comment ... so far, no word back.
