'90210' Star Trevor Donovan Rips 'Greedy Breeders' for Ailing German Shepherd


Trevor Donovan is fed up with “greedy breeders” who are too cheap to test dogs for a disease that leaves the animals’ hind legs paralyzed ... a disease his own German Shepherd is battling.

TMZ caught up with Trevor when the actor was out with his pups, Dogbert and Tito. Dogbert suffers from degenerative myelopathy -- a progressive disease of the spinal cord.  

The "90210" alum told us the disease is totally preventable, but he's pissed because too many breeders pass on a simple lab test.

He showed us how it's affecting Dogbert -- he's already dragging his hind legs, but Trevor's hooked him up with special booties.
