Neeta Verma tends to an accident produced by her excited Labrador retriever cross, Mr. Toquito, during an Ask the Trainer class at Mesa Verde Community Center, 7900 Marquette Ave. N.E. The classes are intended to help people who adopt animals from city shelters with issues that might lead them not to keep their dogs. "Puppy and dog class is of primary importance because well over 75 percent of dogs in the shelter are there because of lack of training," said trainer Diane Sullivan.
