The Morrisville Borough Police Department posted photos on social media of the pets that were left behind.
Authorities say six dogs were abandoned at a park along East Philadelphia Avenue on Saturday.
Officers found a note from the former owner saying he could no longer care for them.
The department says it's best to drop off pets you can no longer care for at a local animal shelter.
Three of the dogs have already been adopted and officials say the remaining three were taken to the SPCA in New Hope.
