STAMFORD - A Stamford veterinarian has charged with criminal trespassing at his former office.

Police say Dr. John Robb was fired by PetSmart in Stamford after he was accused of giving animals half doses of vaccinations.

Police say Robb returned to the store yesterday and was arrested.

Another vet in the practice says they are contacting Robb's clients to come back in for a full vaccination free of charge.
