 Summer can be rough on pets. Between the heat, thunder, and holiday fireworks, pets, both inside and out, can become frantic, looking for a safe haven from the noise. Host of the Pet Show, Warren Eckstein, tells the talk of Delmarva. The number of dogs and cats lost on the Fourth of July weekend is the biggest in the year. It's the busiest day of the year for shelters. Many pets get lost, injured, or killed because the source of the noise is confusing.
