SALEM — A wave of stray dogs this week has overwhelmed the Marion County Dog Control and Shelter.

Office manager Sonya Pulvers told the (Salem) Statesman Journal that fireworks on New Year’s Eve may have led to the increase in strays. The shelter took in 25 dogs Monday and several more Tuesday.

Pulvers said the county holds the dogs for as many as five days before putting them up for adoption. Some may go to dog rescue programs but others are euthanized. The Willamette Humane Society has not seen a similar upswing.
