Another case of a dog left in a hot car, this time in Northampton.  Animal control officers removed an animal left in a parked vehicle near Hancock and Hawley Streets Tuesday afternoon in 90-plus degree temperatures.  Police say when the black lab was removed, the dog had trouble standing.  They say the owner had left a note on the truck instructing anyone who was concerned about the dog's welfare to call a phone number before contacting authorities.  But police say a call to the number wasn't answered.  The owner finally called police several hours later, saying he had been attending a class.  The owner was fined $100.  Apparently this wasn't an isolated case.  Northampton Police Captain Scott Savino tells the Gazette, police are getting numerous calls every day this Summer about animals being left alone in cars.
