... especially for this late in the series. At this point, Quincy had largely evolved into an issues show versus a "murder of the week" mystery show solved by forensic medicine, which was its original format. This rather returns the show to form, no doubt due to sweeps (It was on in May). Plus, who doesn't like dogs?
A guard dog supplied by a reputable kennel attacks and kills a very little girl. Quincy appears on a news item about the killing and, as a result, the kennel loses lots of business. The owner of the kennel, Mike Snyder, goes to talk to Quincy about how he doesn't know how this could have happened given he personally trains his dogs and his dogs are not vicious. He invites Quincy over to see how he trains his dogs and how even when attacking it is not personal with his well trained dogs. They are merely doing their jobs and will halt the attack upon command and do not lose control. Quincy helps Snyder look into what happened and they come across a wild and unbelievable scheme.
This had just a tiny bit of an issue because you are being educated about the proper handling and training of guard dogs, but at least Quincy doesn't spend half the show pounding on his desk screeching that the government must do something. (!!!) There is a cute subplot where Quincy adopts a dog which looks like the last dog on earth that Quincy would adopt - a tiny barking bedroom slipper.
