Kenneth Hyland, 53, of Everett pleaded not guilty at his arraignment in Charlestown District Court.

At least two dogs ended up sick.

Hyland was arrested Friday.  He denies the charges.

He has more than 30 criminal convictions on his record and several aliases.

As a result, his bail was also revoked in two other outstanding cases out of Lynn and Woburn.
